9Ni-4Co-0.20C Steel
Verifiedmetal9Ni-4Co-0.20C is a high-strength, low-alloy steel designed for cryogenic applications, combining nickel and cobalt additions to maintain toughness at extremely low temperatures while the moderate carbon content provides strength. The Q&T (quenched and tempered) condition delivers yield strengths typically 1,380–1,550 MPa with excellent fracture toughness and impact resistance down to liquid helium temperatures, making it suitable for aerospace propellant tankage and cryogenic pressure vessels.

Quality & Standards
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.
