0.90C 7.4Cr-1.4Mo-0.3V-2.7Ni Low Alloy Steel
metalThis is a high-carbon, cobalt-bearing tool steel strengthened by chromium, molybdenum, vanadium, nickel, and tungsten additions—a specialized alloy designed for extreme hardness and wear resistance. The unusually high cobalt content (~13.7%) is characteristic of premium tool steels used in demanding cutting and forming applications where edge retention and thermal fatigue resistance are critical. Engineers select this material for applications requiring exceptional hardness combined with toughness, particularly in high-speed machining tools, die-casting dies, and punch/shear blades where conventional tool steels would fail under thermal cycling or abrasive wear.

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.
