· S8 Cr4 Cu2

S8 Cr4 Cu2 is a tool steel alloy containing chromium and copper additions to an iron-carbon base, formulated to enhance wear resistance, hardenability, and corrosion performance compared to plain carbon steels. This composition sits within the family of medium-alloyed tool steels, commonly used in manufacturing and industrial applications where moderate toughness combined with good surface hardness and dimensional stability are required during thermal cycling or exposure to 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.
