Understanding scrap stainless steel prices is essential for Australian tradespeople, demolition teams, fabricators, and recyclers who want to capture maximum value from off-cuts, obsolete tanks, fittings, and turnings. Stainless steel (SS) is a ferrous metal containing at least 10.5 % chromium, but unlike mild steel it resists corrosion, demands more energy to produce, and therefore commands a premium over ordinary scrap steel.
1. How Australian Scrap Yards Set Stainless Steel Prices
Scrap stainless steel prices are not plucked from thin air. Dealers use three transparent levers:
- London Metal Exchange (LME) Nickel Cash Price – nickel represents 8–10 % of 304 and up to 14 % of 316. When the LME nickel contract rises AUD $1,000 per tonne, expect +8–10 c/kg on 304 turnings.
- Chromium, Molybdenum, and Alloy Surcharges – 316 stainless contains ~2–3 % molybdenum for marine-grade corrosion resistance, so stainless steel scrap metal prices for 316 usually sit 25–35 % above 304.
- FX & Local Supply – Australian yards export 70 % of their containerised material to South Korea, India, and Taiwan. A weaker AUD makes local scrap attractive, pushing prices higher even if global nickel is flat.
Domestic mills such as Outokumpu in Western Australia and Liberty Steel in NSW buy small volumes, but the true price setter is the export bid minus freight, containerisation, and yard margins—typically 12–15 %. For the most recent daily indications, see our Scrap Prices portal.
Tip: Always ask for the “nickel-linked formula” rather than a flat rate; reputable yards will email you a spreadsheet showing the LME tick and the kg credit applied.
2. 304 vs 316 and Other Common Grades Explained
Not all stainless is equal. Mis-sorting 316 into a 304 bin can wipe 30 % off your payment. Here is the field guide Australian buyers use:
- 304 (18-8) – 18 % chromium, 8 % nickel, no moly. Found in kitchen benches, domestic sinks, architectural cladding, beer kegs. Magnetic after cold work, but lightly so. Current Stainless Steel Scrap Price range $0.80–$1.60 kg.
- 316 (Marine) – adds 2–3 % Mo. Used on boat rails, pool ladders, chemical pipework. Non-magnetic in annealed form. Pays 20–40 c/kg more than 304. Check the moly spot; when moly oxide is above USD 20/lb, the spread widens.
- 430 (Ferritic) – 17 % Cr, no nickel. Magnetic, used in dishwasher panels, automotive trim. Trades closer to mild steel—think $0.35–$0.55 kg.
- 2205 Duplex – 22 % Cr, 5 % Ni, 3 % Mo. Extremely strong and corrosion-resistant. Mills pay a premium, but volume is low. Positive material identification (PMI) gun required.
- Turnings & Swarf – carry cutting fluid, dirt, and lower density. Yards apply a 20–40 c/kg deduction plus “dry weight” sampling.
Practical tip: carry a portable analyser (XRF) or at least a Mo-test reagent drop. A green colour change indicates 316 within seconds, saving you from downgrades.
3. Price Volatility: What History Tells Us
Over the past decade, scrap stainless steel prices have swung wildly. In 2016, 304 turnings bottomed at $0.48 kg when LME nickel hit USD 7,650 t. By March 2022, Russian invasion fears drove nickel to an intraday USD 101,365 t and Australian 304 solids briefly touched $3.10 kg before profit-taking collapsed the quote. Such spikes last days, not months, so timing matters.
Key volatility drivers:
- Indonesian ore export bans – Indonesia supplies 35 % of global nickel laterite. When Jakarta froze exports in 2020, LME surged 40 % within a month.
- ESG premiums – battery-grade nickel sulphate competes with stainless feed, pushing scrap into a supply squeeze.
- Freight shocks – post-pandemic container shortages added USD 400 t to landed freight, compressing local bids.
Hedging tool: some forward-thinking yards now offer “nickel-linked swaps” locking 30-day prices. Fabricators with large sheet metal waste can budget without surprises.
4. Environmental Benefits and the Circular Stainless Loop
Recycling one tonne of stainless scrap saves 4.3 t CO₂ compared with virgin ore-based production, according to the International Stainless-Steel Forum. Australia currently recycles only 52 % of available stainless arisings, so there is upside.
How the loop works:
- Collection – off-cuts from sheet metal shops, demolished brewery tanks, household dishwashers.
- Sorting – magnetic separation removes mild steel, then X-ray sorting isolates 304, 316, 430.
- Baling & Shearing – dense 30 × 30 cm bundles improve furnace yield.
- Melting – Electric Arc Furnaces (EAF) at sites like @Liberty Whyalla add 75 % scrap charge, slashing energy 65 %.
- Remelt Products – new rebar, bridge bearings, even surgical implants.
Stainless is 100 % recyclable and suffers no property loss. By selling your material to Scrap.Trade you guarantee closed-loop re-melt rather than landfill.
5. Maximising Dollar Value: Practical Tips for Sellers
- Decontaminate – remove rubber gaskets, plastic labels, copper heating elements. One copper nut in a 5 t load can trigger “contaminated” downgrade worth $200 t.
- Cut to spec – yards pay freight on oversized pieces. Keep lengths under 1 m and weight per piece under 15 kg to avoid reprocessing fees.
- Keep dry – wet turnings weigh more, but yards deduct moisture after lab sampling. Store swarf under cover.
- Bundle like with like – never mix 304 and 316. If uncertain, quote as 304 and let the yard upgrade you after PMI; psychology works in your favour.
- Time the market – watch LME nickel 3-month, USD/AUD, and Indonesian policy headlines. Sell on the first Friday of each month when mills place orders.
- Negotiate assay return – reputable yards return a 2 % nickel credit if your assay beats the assumed grade. Ask for the lab printout.

6. Tools & Resources for Daily Tracking
Successful traders check prices before breakfast. Bookmark these:
- Scrap.Trade – publishes live stainless steel prices for scrap for 17 Australian cities, updated 08:30 AEST.
- LME Official Nickel – available via the London Metal Exchange app; set an alert at USD 18,000 t to catch cyclical lows.
- Fastmarkets AMM – US-based but correlates 0.94 with Australian bids after FX adjustment.
- Scrap Buddy calculator – free Android/iOS app; enter kg and grade, spits out AUD value minus yard fees.
Pro tip: export yards quote CFR Busan (South Korea). Convert CFR to ex-yard by subtracting USD 90 t freight and USD 40 t container handling. If your dealer margin exceeds 12 %, shop elsewhere.
7. Frequently Overlooked Revenue Streams
Many contractors leave money on the table because they only target “big ticket” copper. Consider these hidden flows:
- Hospital upgrades – old sterilisers and operating theatre lights contain 316L shells worth $1.50 kg.
- Food processing plants – conveyor segments and hoppers are often 304; a single decommissioned chicken nugget line can yield 6 t.
- Service station canopies – 430 cladding is light gauge but a full canopy weighs 2–3 t and attracts 550 c/kg.
- Swimming pool heat exchangers – almost always 316 and already unplumbed by plumbers.
Partner with demolition surveyors and offer a revenue-share; you’ll secure first right of refusal on stainless arisings.
8. Looking Forward: 2025–2027 Outlook
CRU forecasts global stainless crude output to grow 4 % CAGR, driven by renewable energy infrastructure (solar panel frames, tidal turbine housings). Indonesia’s new NPI-to-matte refineries will raise Class-I nickel supply, putting mild downward pressure on scrap stainless steel prices, yet ESG-driven scrap usage mandates in the EU and forthcoming Australian recycling targets will counterbalance.
Bottom line: expect 304 to trade in a narrower AUD $1.00–$1.80 kg band, with seasonal dips in Q1 when mills destock. Forward-selling contracts and flexible yard relationships will insulate your margins.

Conclusion: Capture More Value from Your Scrap
Scrap stainless steel prices fluctuate with nickel, molybdenum, and currency markets, but the fundamentals are clear: Australia generates hundreds of thousands of tonnes of arisings each year, and only half finds its way back into furnaces. By understanding grades, monitoring global drivers, and preparing clean, sorted loads, you can consistently beat the average yard quote.

Frequently Asked Questions
What is the current scrap stainless steel price per kg?
As of June 2024, 304 solids fetch $0.80–$1.60 kg and 316 solids $1.10–$2.00 kg. Prices update daily with LME nickel and the AUD/USD rate.
How can I tell 304 from 316 stainless?
Use a moly drop test (green colour) or a portable XRF gun. 316 is typically non-magnetic and marked ‘Mo’ on industrial tags.
Why do scrap yards pay less for turnings?
Turnings contain coolant, dirt, and trapped air, reducing melt yield. Yards apply a 20–40 c/kg deduction and quote on dry weight.
