2. Chemical Composition of 304 Stainless Steel Coil

The performance of 304 stainless steel comes from its precise chemical composition. Below is the standard requirement according to ASTM A240.

Element	304 (%)
Carbon (C)	≤0.08
Chromium (Cr)	18.0 – 20.0
Nickel (Ni)	8.0 – 10.5
Manganese (Mn)	≤2.00
Silicon (Si)	≤0.75
Phosphorus (P)	≤0.045
Sulfur (S)	≤0.03
Nitrogen (N)	≤0.10
Iron (Fe)	Balance

Note：The high chromium and nickel content gives 304 stainless steel its signature corrosion resistance and toughness.

Frequently Asked Questions (FAQ)

Q1：What is the difference between 304 and 304L stainless steel coil?

A：304L has lower carbon content (≤0.03% vs ≤0.08% for 304). This makes 304L more suitable for welding applications where carbide precipitation is a concern. For most general applications, 304 is sufficient and more cost-effective.

 

Q2：Do you provide slitting services for 304 stainless steel coil?

A：Yes. We can slit coils to custom widths according to your requirements. Please provide your desired width and tolerance.

 

Q3：What surface finishes are available for 304 coil?

A：We offer 2B (bright), BA (mirror-like), No.1 (hot-rolled), HL (hairline), No.4 (brushed), and mirror finish. Contact us with your surface requirement.

 

Q4：Can you provide samples before bulk order?

A：Yes. Free samples are available for your evaluation. You only need to cover the shipping cost.

 

Q5：What is the lead time for 304 stainless steel coil?

A：Standard sizes are in stock – lead time is 7–10 days. For custom sizes or large quantities, lead time is 15–20 days.

 

Q6：Do you provide Mill Test Reports (MTRs)?

A：Yes. Every coil shipment comes with MTRs certifying chemical composition and mechanical properties. Third-party inspections (SGS, BV, etc.) are also accepted.

 

Q7：Do you export 304 stainless steel coil to my country?

A：We export worldwide including USA, Canada, UK, Germany, France, Australia, Brazil, UAE, Saudi Arabia, South Africa, Thailand, and more. Contact us with your shipping address.
