The scrap price for 316 stainless steel is the highest among common stainless grades because of 10 % nickel and 2 % molybdenum content, making it more valuable than 304 stainless or mild steel scrap. This pillar guide explains how Australian yards set the daily rate, what factors move the market, how to sort and sell 316 for maximum profit, and why recycling this non-ferrous metal is both lucrative and environmentally critical.
How Australian Scrap Yards Set the 316 Stainless Steel Price
Scrap yards do not invent numbers; they follow a transparent pricing stack that begins at the London Metal Exchange (LME) and ends at your local weighbridge. The process is:
- LME nickel and molybdenum cash prices are published at 17:00 London time. Nickel is the dominant driver because 316 contains 10–12 % Ni and 2–3 % Mo. Every USD 100 cent move in nickel changes the intrinsic value of 316 by roughly AUD 0.11 per kg.
- Currency conversion happens at the mid-market AUD/USD rate plus a 1.5–2 % hedging margin applied by buyers.
- Freight and smelter margins are deducted. Most Australian 316 is exported to South Korea, Taiwan, or India. Container freight from Sydney to Busan is currently USD 1 300–1 500 per tonne; this equates to AUD 0.13 per kg off the gate price.
- Purity discounts are applied. Clean 316 solids (valve bodies, pump housings, marine hardware) receive full price. Turnings contaminated with free iron or 304 stainless scrap are downgraded 20–40 cents per kg.
- Site overheads (rent, labour, compliance) average 8–10 % of revenue. The final Stainless Steel Scrap Price you see on the yard’s whiteboard already includes these deductions.
Prices are updated twice daily—once at 07:00 when Asian markets open and again at 16:00 after the LME kerb. To lock in the best scrap price for 316 stainless steel, deliver before the second update; yards rarely back-date if the market falls overnight.
Factors That Move the 316 Stainless Scrap Market
Understanding the moving parts helps you decide when to stockpile and when to sell.
- Nickel supply shocks. Indonesia exported 520 kt of nickel pig iron in 2023, but any sudden ore export ban adds instant volatility to the 316 stainless steel scrap price.
- Stainless melt rates in China. Chinese stainless output is 60 % of global supply. When Tsingshan or Baosteel ramp 300-series production, demand for 316 scrap rises and prices firm.
- USD strength. Because nickel is USD-denominated, a stronger greenback lowers AUD-denominated prices even if LME is flat.
- Replacement ratio. Mills compare the cost of 316 scrap versus 304 stainless plus high-purity nickel. If the spread narrows, buyers substitute 304 for 316 and the premium shrinks.
- Seasonal demolition flows. Q4 is peak demolition season; coastal sugar mills and breweries replace 316 heat-exchanger tubes, pushing local supply up 15–20 % and temporarily weighing on prices.
Track these indicators weekly and you can anticipate swings of ±AUD 0.25 per kg in the price for stainless steel scrap.
316 vs 304 vs Other Stainless Grades—Know Your Alloy
Not all stainless is created equal. Mis-sorting 316 into a 304 stainless pile can cost you over one dollar per kg.
| Grade | Ni % | Mo % | Magnetic? | Typical Gate Price AUD/kg |
|---|---|---|---|---|
| 316 | 10–12 | 2–3 | Slightly | $2.80–$3.40 |
| 304 | 8 | 0 | Slightly | $1.70–$2.10 |
| 430 | 0 | 0 | Yes | $0.65–$0.85 |
| 2205 Duplex | 5 | 3 | Yes | $2.20–$2.60 |
Use a moly drop test—a single drop of 10 % ammonium molybdate turns deep green on 316 but stays clear on 304. For large lots, handheld XRF analysers are now standard at yards such as Scrap.Trade; they grade your load in under 90 seconds.
Remember that 316 is non-ferrous but still exhibits slight magnetism because of cold working. Do not rely on magnets alone when optimising the Stainless Scrap Price How To Sell Stainless Steel Scrap For Maximum Profit.
How to Prepare and Sell 316 Stainless for Top Dollar
Follow this checklist to move from “dirty scrap” to “clean 316 solids” and capture every cent:
- De-oil and de-plastic. Heat-exchanger tubes often carry rubber gaskets and oily residue. Thermal de-oiling adds AUD 0.15 per kg but increases the price differential by AUD 0.30—pure profit.
- Cut attachments. Steel bolts, mild steel brackets, and sheet metal off-cuts downgrade the entire bin to “mixed non-ferrous” and you will be paid 304 prices. Use a plasma cutter to remove ferrous metal attachments.
- Separate turnings. 316 turnings are priced 30–40 cents lower than solids because of entrapped cutting oil and lower density. Keep them in a separate drum and sell when you have 500 kg to negotiate volume bonus.
- Provide mill certificates. If you are demolishing a chemical plant, keep the original MTR (mill test report). Yards pay an extra AUD 0.10 per kg for certified 316L (low carbon) because they can on-sell to specialty foundries.
- Time the payment terms. Spot cash carries a 2 % discount. If you can wait 7-day EFT, ask for full published price.

Recycling Process: From Gate to New 316 Rebar
Once your material crosses the weighbridge, the journey to a brand-new stainless rebar begins:
- Shredding and delacquering. Scrap is shredded to <50 mm and passed through a 400 °C thermal oxidiser to remove PVC coatings and grease.
- Media separation. Eddy-current separators eject any remaining non-ferrous metal contaminants; magnetic pulleys pull free iron.
- Melting in an electric-arc furnace at 1 550 °C. Lime and fluorspar fluxes remove sulfur; oxygen lancing reduces carbon to 0.03 % for 316L.
- Argon-oxygen decarburisation (AOD) lowers the carbon content without chromium loss, preserving corrosion resistance.
- Continuous casting into 150 mm billets, then hot-rolling to rebar, angle, or sheet metal products.
Recycling 1 tonne of 316 stainless saves 1.1 tonnes of ni ore, 0.4 tonnes of mo ore, and 4.3 MWh of energy—enough to power an average Melbourne home for 14 months.
Environmental and Economic Benefits of 316 Recycling
Australia generates ~550 kt of stainless steel scrap annually, yet 30 % still goes to landfill. Diverting 316 has outsized benefits:
- Carbon footprint. Primary 316 production emits 6.8 t CO₂-e per tonne; secondary scrap route emits only 1.1 t—a saving equal to taking 1 300 cars off the road for every 10 kt recycled.
- Resource security. Australia imports 100 % of its nickel ore. Every kg of 316 recycled reduces import dependency and keeps AUD in the local economy.
- Landfill space. Stainless is inert but occupies valuable airspace; 316 is dense and does not compact well.
- Green premium. Buyers of ScrapTrade.com.au verified recycled content can claim Scope 3 emission reductions, pushing demand—and price—for clean 316 feedstock.
Government incentives are coming: the proposed NSW Circular Materials Fund offers AUD 50 per tonne rebate for stainless that meets >95 % recovery. Watch for announcements in Q3 2024; early adopters will capture both the rebate and the higher scrap price for 316 stainless steel.
Storage and Safety Tips for 316 Stainless Scrap
316 may be corrosion-resistant, but improper storage still costs money:
- Keep it dry. Chloride pitting from marine air can cause brown staining; buyers may discount 5 cents per kg for “rusty” 316 even though it is only surface.
- Stack on timber dunnage. Direct contact with carbon steel supports leads to galvanic rust marks and downgrading.
- Segregate by form. Solids, turnings, and plate off-cuts should be in separate cages; cross-contamination is the number-one reason for price disputes.
- Secure the yard. 316 is valuable; thieves often mistake it for mild steel. Paint the last 100 mm of each bundle bright yellow to deter theft and to signal “high-value non-ferrous metal”.
Future Outlook: Where Is the 316 Stainless Scrap Price Heading?
Three macro trends will dominate the next 24 months:
- Indonesian nickel matte projects are ramping, which could add 200 kt of Class I nickel to the market and soften prices. However, downstream stainless mills prefer scrap for ESG reporting, limiting downside to ~AUD 0.30 per kg.
- Australia’s offshore wind build requires 316 cable ladders and fasteners; domestic demand for scrap will rise 8 % per annum, supporting local premiums.
- Carbon border tariffs (EU CBAM) start phasing in 2026. Australian exporters of 316 scrap to Europe may receive a credit for recycled content, pushing the scrap price for 316 stainless steel premium another 5–7 % above LME parity.
Bottom line: expect volatility between AUD 2.60–$3.60 per kg, but structural demand for low-carbon 316 feedstock keeps the long-term trend intact.

Frequently Asked Questions
What is the current scrap price for 316 stainless steel per kg in Australia?
As of June 2024, clean 316 solids fetch AUD $2.80–$3.40 per kg at major yards in Sydney and Melbourne, depending on nickel and molybdenum prices.
How can I tell the difference between 316 and 304 stainless scrap?
Use a moly drop test—316 turns green in seconds—or a handheld XRF gun. 316 is slightly magnetic but contains 2 % molybdenum, whereas 304 has none.
Should I remove steel bolts from my 316 scrap?
Yes. Any ferrous metal attachment downgrades the load to ‘mixed non-ferrous’ and you lose around AUD 1 per kg. A quick plasma cut pays for itself.
Is 316 stainless scrap worth more than aluminium or copper?
Per kilo, 316 is below bright copper but well above aluminium. Its high nickel and molybdenum content makes it the most valuable stainless grade commonly traded.
