· JVASP-127340· CrMo

CrMo is a chromium-molybdenum alloy steel that combines chromium's corrosion resistance with molybdenum's strength and hardness, creating a tough, wear-resistant material. It is widely used in high-stress applications requiring fatigue resistance and toughness, including automotive components (axles, gears, crankshafts), heavy machinery, and pressure vessels. Engineers select CrMo over plain carbon steels when superior hardness and fatigue performance are needed, and over stainless steels when cost must be minimized while maintaining adequate corrosion resistance for non-corrosive or mildly corrosive environments.

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.
