Product Description

303 Stainless Steel Bar

303 Stainless Steel Bar

303 stainless steel bar was developed for machining. Type 303 has a higher concentration of sulfur reducing the drag on cutting tools. It allows greater machining speeds and lower production costs. The alloy is useful whenever a need arises for good corrosion resistance and considerable machining is required.

Applications of 303 Stainless Steel Bar:

Available shapes: Hexes, Rounds, Squares
Specifications: ASTM A582, AMS 5640, AMS QQ-S-764B Cond A

Austenitic steels have austenite as their primary phase (face centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. Austenitic steels are not hardenable by heat treatment. The most familiar stainless steel is probably Type 304, sometimes called T304 or simply 304. Type 304 surgical stainless steel is austenitic steel containing 18-20% chromium and 8-10% nickel.
