Stainless steel TP316/316L seamless pipe/ Bar/Sheet/strip/Bolt

Product Detail

Common Trade Names: 316 Stainless/316L Stainless,UNS S31600/UNS S31603, Werkstoff 1.4401/Werkstoff 1.4404

316/316L is the most commonly used austenitic stainless steel in the chemical process industry. The addition of molybdenum increases general corrosion resistance, improves chloride pitting resistance and strengthens the alloy in high temperature service. Through the controlled addition of nitrogen it is common for 316/316L to meet the mechanical properties of 316 straight grade, while maintaining a low carbon content.

Why 316/316L ?

Shows better overall corrosion resistance than grade 304, especially for pitting and crevice corrosion in chloride environments.
In addition.
316/316L alloys have excellent high temperature tensile, creep and endurance strength, as well as excellent formability and weldability.
316L is a low-carbon version of 316 and is immune to sensitization
