SS321 stainless steel is a highly valued titanium‑stabilized alloy prized for its high temperature strength, corrosion resistance, and durability in aggressive environments. As of 2026, SS321 is widely recycled and sought after in Australia’s scrap market because it combines excellent performance with high alloy content making it ideal for buyers who process and remelt premium grades.
This guide explains what SS321 scrap is, how its pricing works, the factors that influence its value, and how to buy or sell it effectively in Australia’s 2026 market.
What Is SS321 Stainless Steel?
SS321 is an austenitic stainless steel alloy similar to SS304 but enhanced with titanium stabilization, which helps prevent chromium carbide precipitation during welding or high‑temperature service.
Key Characteristics:
- Titanium‑stabilized to resist sensitization
- Excellent oxidation resistance at elevated temperatures
- Good corrosion resistance in atmospheric and mild chemical environments
- Frequently used in furnace components, exhaust systems, and heat‑exposed structural parts
Due to its specialized alloying, SS321 retains significant recycling value when reclaimed as scrap.
SS321 Stainless Scrap Price Australia 2026
Prices for SS321 scrap vary depending on alloy purity, weight, contamination, and market demand. Because SS321 contains elements like titanium, nickel, and chromium, it typically commands a higher scrap rate compared to common stainless grades.
Indicative SS321 Scrap Price Range (per kg, AUD):
| Material Condition | Price Range (AUD/kg) |
|---|---|
| Clean, sorted SS321 scrap | $5.00 – $7.00 |
| Mixed stainless including SS321 | $3.50 – $5.00 |
| Heavily contaminated stainless scrap | $3.00 – $4.00 |
Actual prices can vary based on global alloy markets, buyer competition, and shipment volumes.

Factors That Influence SS321 Scrap Value
Alloy Composition
Titanium stabilization and high chromium/nickel content elevate the intrinsic value of SS321.
Market Demand
Buyers in industrial, chemical, and high‑temperature fabrication sectors pay premiums for high‑quality scrap.
Purity & Cleanliness
Clean, well‑sorted SS321 without non‑metal contaminants (plastic, rubber, etc.) attracts top pricing.
Quantity & Volume
Bulk consignments typically receive better per‑kg pricing than small or mixed lots.
Global Alloy Metals
Prices for chromium and nickel heavily influence stainless scrap pricing.
How to Sell SS321 Scrap in Australia
1. Sort by Alloy Grade
Separate SS321 from other stainless grades (like SS304, SS316) for the best pricing.
2. Clean Contaminants
Remove non‑metal materials like plastic, paint, and rubber to maximise alloy purity.
3. Weigh Accurately
Use certified scales for transparent weight metrics net of contaminants.
4. List on a Verified Marketplace
Rather than selling to a single local dealer, reach multiple verified buyers to compare offers.

FAQs — SS321 Stainless Scrap
Q1: Is SS321 more valuable than SS304?
Yes — due to its titanium stabilization and exceptional high‑temperature properties, SS321 often commands higher scrap pricing.
Q2: Can I mix SS321 with other stainless grades?
It’s best to keep SS321 separate. Mixed grades dilute value and usually trade at reduced per‑kg rates.
Q3: Do buyers require documentation for SS321?
Many buyers appreciate grade verification or photos, especially for premium alloys like SS321.
Q4: Can I sell small quantities?
Yes — verified online marketplaces accept both small and bulk consignments.
Q5: Does location affect pricing?
To an extent, yes — proximity to buyers, ports, and transport infrastructure can influence net value.
Conclusion
SS321 stainless scrap is a high‑value titanium‑stabilized grade that continues to deliver strong pricing in Australia’s 2026 recycling market. Whether you are a fabricator selling leftover alloy or a recycler handling industrial scrap, sorting this material, preparing it properly, and selling through a verified buyer network ensures competitive pricing and secure transactions.
