Grade 304 is the most commonly used stainless steel. It is an austenitic, corrosion-resistant steel with excellent strength, toughness, fabrication characteristics and weldability. The low carbon version, 304L, may be required for full corrosion resistance when thicker sections are welded.
304L stainless Steels lower carbon content helps minimize/eliminate carbide precipitation during the welding process. This allows 304L stainless steel to be used in the “as-welded” state, even in severely corrosive environments.
309 stainless steel has a higher corrosion resistance and strength compared to 304 stainless steel. This product is versatile and known for its high heat treatment capabilities.
Stainless steel 310/310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000°F. Stainless 310 is often used at cryogenic temperatures, with excellent toughness to -450°F, and low magnetic permeability.
310S stainless steel sheets is similar to stainless steel 310 apart from a lower content of carbon that reduces carbideprecipitation and enhances weldability. The soaring nickel and chromium contents of ss 310s plates offer similar corrosionresistance, higher resistance to oxidation and the holding of a superior portion of room temp potency than the usual austeniticsteel such as S304.
Type 316 stainless steel is an austenitic grade with added molybdenum. The alloy offers improved corrosion resistance when compared with Type 304, particularly in chloride environments.
Stainless Steel 317 and 317L are molybdenum-bearing austenitic stainless steels. Due to the molybdenum content of 3-4% 317 and 317L are more resistant to general corrosion and pitting/crevice corrosion than type 304. 317 and 317L are used in the Food, Pharmaceutical, Marine and Architecture industries.
Stainless Steel 321 has similar composition to 304 Stainless Steels but with addition of Titanium. This alloy has excellent resistance to corrosion and is also ideal for high temperature environments.
904L is a stainless steel alloy that displays high resistance to corrosion, particularly against acidic environments. Therefore, 904L isapproved for use in acid production and concentration, along with the transport of such substances.
With excellent weldability and formability 904L also maintain non- magnetic state in all conditions.
904L provides excellent toughness , even down to cryogenic temperatures with its austenitic structure.
