TP 201LN, UNS S20153 Alloy Round Bar X2CrMnNiN 17-7-5 W-Nr 1.4371 Flat Bright Bar
Product Information
Stainless steel 201LN is a traditional Cr-Ni austenitic stainless steel, even at low temperature, 201LN stainless steel can provide good resistance
Easy to oxidize, easy to process, good toughness. SS 201LN is not expensive because of lower cost nitrogen, and manganese is added as a partial replacement for nickel
