Product Q&A

Q:What is SUS303 and how does it differ from 304?

SUS303 (UNS S30300) is a free-machining austenitic stainless steel based on 304, with added sulfur (0.15-0.35%) for chip breaking. It machines up to 40% faster and wears tools less, but its corrosion resistance, weldability and formability are slightly lower than 304. Choose 303 when machining speed and tight tolerances matter most; choose 304 when welding or maximum corrosion resistance is required. FUSHUN METAL supplies both grades with full mill certificates.

Q:What sizes, shapes and delivery states does FUSHUN METAL offer?

We supply SUS303 as rolled round bar (8-300 mm dia.), rolled flat bar (3-60 mm thick, 10-300 mm wide) and cold-rolled strip (0.1-6.0 mm thick, 5-600 mm wide). Delivery conditions include annealed, peeled, centerless-ground, cold-drawn and polished; surfaces range from black and pickled to bright and mirror. Lengths run 3000-6000 mm or cut to your drawing.

Q:Do you provide mill test certificates and which standards do you meet?

Yes. Every SUS303 order ships with an EN 10204 3.1 Mill Test Certificate covering heat number, chemical analysis and mechanical properties. FUSHUN METAL is ISO 9001 certified and produces to JIS G4303, ASTM A582/A484, EN 10088-3 and AMS 5640, with PMI and ultrasonic inspection on request to guarantee traceability and defect-free bars.
