AISI/SAE 52100 Round Bars

AISI/SAE 52100 Round Bars for machining, forging and shaft work, available on MetalMitra in round, square and hex, with mill-certified traceability on every lot.

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

AISI 52100 is a high-carbon chromium bearing steel with very high hardness and wear resistance. Controlled additions of chromium, molybdenum, nickel or vanadium give alloy steel higher strength, deeper hardenability, better toughness and stronger performance at elevated temperature.

Product range
