Sold by NUMAX STEELS

Numax Steels are the supplier and stockist of PH Series, SMO 254, Alloy 20 & 904L Round Bars. Stainless Grade 17-7 PH is a combination hardening stainless steel that provides strength and hardness, best fatigue features, corrosion resistance & formability, and minimum distortion upon heat treatment. The 17/4 provides valuable property combinations particularly well suited for aerospace applications. 17/4 stainless steel in all heat treated conditions, like other types of stainless steels – will develop superficial rust in some environments. 904L is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Alloy 20 is an austenitic, nickel-iron-chromium based super alloy with additions of Copper and Molybdenum which provide resistance to hostile environments, pitting, and crevice corrosion.
