Low-alloy filler metals: From A to W

October 22, 2014

By:

Low alloy steels gain their mechanical and chemical properties from the addition of alloying elements, including nickel, chromium, molybdenum, and manganese. They typically offer an ultimate tensile strength of 80,000 PSI or greater, and as with any material, they require a filler metal that matches their chemistry and provides the desired strength.
