Product Description

300M Alloy Steel is a vacuum-melted, low-alloy steel that is essentially a modification of AISI 4340 with added Silicon (approx. 1.60%). This addition allows the material to be tempered at higher temperatures while maintaining extreme hardness and preventing embrittlement, resulting in one of the highest strength-to-weight ratios of any low-alloy steel.
