SUS316N、S31651

Stainless steel: SUS316N

Features and applications:

SUS316N is the addition of N to 316 steel, which improves the strength, but does not reduce the plasticity, making the thickness of the material thinner. SUS316N has good corrosion resistance, heat resistance and mechanical properties; good hot workability such as stamping and bending, no heat treatment and hardening; molybdenum and low carbon content, excellent resistance to pitting corrosion in marine and chemical industrial environments In 304 stainless steel.

SUS316N is mainly used as a high-strength component with good corrosion resistance. Such as seawater equipment, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment and photographs, food industry, coastal facilities, ropes, CD rods, bolts, nuts, etc.
