1.55C High Carbon Steel

metal

1.55C High Carbon Steel is an ultra-high carbon ferrous alloy with substantial nickel (16.7%) and silicon (9%) additions, creating a hard, wear-resistant material designed for extreme strength and edge retention. This composition—likely a specialized tool steel or bearing steel variant—is found in precision cutting tools, dies, gauges, and applications demanding exceptional hardness and minimal deformation under load. Engineers select this alloy when conventional carbon steels cannot meet wear resistance or dimensional stability requirements, though the low elongation reflects the brittle nature typical of high-carbon, highly alloyed systems.

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.
