817M40 alloy steel, also known as EN24T, is a high-strength engineering steel renowned for its excellent combination of toughness, wear resistance, and high tensile strength. It is a nickel-chromium-molybdenum through-hardening steel that maintains its mechanical properties even in large cross-sections, making it a reliable choice for demanding industrial applications.

At Nifty Alloys, we specialize in the supply of high-quality 817M40 alloy steel, ensuring every product meets rigorous international standards. Our commitment is to provide you with certified, traceable materials that deliver the performance and reliability your operations require.

What is 817M40 Alloy Steel?

817M40 is a versatile alloy steel typically supplied in the 'T' condition, signifying it has been hardened and tempered to achieve its optimal mechanical properties. This treatment process gives it a fine-grained martensitic structure, which is the source of its superior strength and toughness. Its balanced chemical composition provides good ductility and resistance to shock loads, distinguishing it from other carbon and alloy steels.

When your project demands a material that can withstand high stress, fatigue, and wear, 817M40 provides a dependable solution. We ensure that every batch of 817M40 steel we supply is accompanied by mill test certificates (MTRs), guaranteeing compliance and full traceability.
