Alloy Steel F12 A182 Round Bars

Source Alloy Steel F12 A182 Round Bars from verified mills, manufacturers and stockists on MetalMitra. Options span round, square and hex, produced to ASTM A182, and every order can ship with an EN 10204 3.1 certificate.

This range covers round, square, hex and flat sections in bright, black, peeled or forged condition, ready for machine shops and component makers.

Grade 12 is a 1Cr-½Mo alloy steel suitable for elevated-temperature service. Controlled additions of chromium, molybdenum, nickel or vanadium give alloy steel higher strength, deeper hardenability, better toughness and stronger performance at elevated temperature.
