Features
- Most popular general-purpose stainless steel. Good resistance to atmosphere, fresh water & weak acid. NOT suitable for chloride / seawater environment (select 316L)
- Excellent formability for deep drawing & bending, good weldability
- Continuous service temperature ≤300℃. Food contact version available with certification
Applications
Food machinery, kitchenware, water tanks, pressure vessels, enclosures, architectural cladding, piping, medical housings, mild chemical equipment
Material Selection Guide
Grade comparison 304: Balanced performance, high volume & cost-effective 316L: Mo added, chloride & seawater resistant, higher price 304L: Low carbon (C≤0.03), better intergranular corrosion resistance after welding 301: High work-hardening for springs & reeds, poorer corrosion resistance
