Forms we supply
Stainless steel in every common form.
Austenitic, ferritic and martensitic stainless steels — from 200-series and 304/316 workhorses to heat-resisting 310S and high-alloy 904L — supplied against ASTM, ASME and EN specifications.
Corrosion & temperature resistance
Corrosion resistance rises with chromium, molybdenum and nitrogen: 304 handles general atmospheric and food-contact service, 316/317 add resistance to chlorides and pitting, 904L handles strong reducing acids, and stabilised 321/347 resist intergranular attack after welding or high-temperature exposure.
Applications
Process piping, tanks and vessels, heat exchangers, food, dairy and pharmaceutical equipment, architectural work and general engineering.
