Washington Alloy, TS308L-SI 121, Welding Filler Metal, ER420, .035 in, Martensitic Stainless Steel, 98,000 psi, 18% Elongation

ER420 is a martensitic stainless steel similar to USA 410, but with a higher level of carbon. This increased carbon content gives the welddeposit greater hardness, providing for excellent abrasion resistance as well as moderate corrosion resistance. Weld deposits will work-harden when put into service and so this filler metal is commonly used for surfacing applications. Preheat and post-weld heat treatment is recommended.
