0.05C 9.6Cr-1.9Mo-8.0Ni Low Alloy Steel

metal

This is a high-strength, low-alloy martensitic steel (approximately 9.6% Cr with significant Ni and Mo additions) designed for applications requiring exceptional hardness and wear resistance combined with controlled toughness. The composition balances chromium for corrosion and wear resistance, nickel for toughness and hardenability, and molybdenum for strength and thermal fatigue resistance—making it well-suited for demanding service environments where conventional high-carbon steels would be brittle. This steel family is commonly specified in aerospace, tool manufacturing, and heavy industrial equipment where fatigue resistance, dimensional stability, and abrasion resistance are critical and cost-to-performance balance favors it over precipitation-hardened stainless steels or cobalt-based alloys.

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
