Stainless steel scrap is a high-value recyclable material, but not all stainless steel is created equal. Among the most commonly recycled grades in Australia are SS304 and SS316. Understanding the differences between these two grades is essential for scrap sellers, buyers, and industrial recyclers looking to maximize returns in 2026.
This guide explains grade characteristics, price differences, applications, and how to sell SS304 and SS316 scrap effectively.
What Is SS304 Stainless Steel?
SS304 is the most widely used stainless steel grade. It is an austenitic alloy with the following properties:
- Composition: 18–20% chromium, 8–10.5% nickel
- Corrosion Resistance: Good, suitable for indoor and moderately corrosive environments
- Applications: Kitchenware, appliances, HVAC systems, industrial equipment
In scrap recycling, SS304 is highly sought after because it is abundant, easy to process, and retains high alloy value.
What Is SS316 Stainless Steel?
SS316 is a marine-grade stainless steel with enhanced corrosion resistance. Its key features include:
- Composition: 16–18% chromium, 10–14% nickel, 2–3% molybdenum
- Corrosion Resistance: Superior, especially against chlorides and saltwater
- Applications: Marine fittings, chemical equipment, offshore and coastal projects, high-performance fabrication
The addition of molybdenum increases both corrosion resistance and market value, making SS316 scrap more expensive than SS304.
Key Differences Between SS304 and SS316
| Feature | SS304 | SS316 |
|---|---|---|
| Chromium Content | 18–20% | 16–18% |
| Nickel Content | 8–10.5% | 10–14% |
| Molybdenum | None | 2–3% (improves corrosion resistance) |
| Corrosion Resistance | Good | Excellent, especially in marine environments |
| Common Applications | Kitchenware, appliances, ducts | Marine, chemical, offshore structures |
| Scrap Value | Moderate | Higher due to alloy content |

FAQs – SS304 vs SS316 Scrap
Q1: Why is SS316 scrap more expensive than SS304?
SS316 contains molybdenum which enhances corrosion resistance, especially in marine environments, making it more valuable.
Q2: Can I mix SS304 and SS316 scrap?
Mixing reduces per-kg value. Sorting by grade ensures maximum returns.
Q3: How is SS304 scrap used after recycling?
It is melted and reformed into industrial equipment, appliances, and construction materials.
Q4: Are there verified platforms for selling stainless steel scrap?
Yes. Verified platforms like Scrap Trade ensure secure, competitive, and transparent sales.
Q5: Does the quantity affect the price?
Yes. Bulk lots of SS304 or SS316 often attract higher per-kg pricing due to lower handling costs.
