X2CrTiNb18 W-Nr 1.4509 Stainless True Bar UNS S43940 Plates
X2CrTiNb18 W-Nr 1.4509 Stainless True Bar UNS S43940 Plates
Product Information
1.4509 is a stainless steel material, also known as AISI 441 or EN 1.4509. It is a low-carbon duplex stainless steel with high corrosion resistance and wear resistance. The chemical composition of 1.4509 material includes chromium, molybdenum, copper, and titanium, with a high chromium content that can give it good corrosion resistance.
