AMS 6481 technical specifications bearing applications, round bar, plate K32340 properties EAF + LF + VD Steelmaking, ESR melted, hot bloomed, forged, rolled, heat treated
Alloy structural steel is provided with higher yield strength, tensile strength, endurance strength, yield ratio (about 0.85 generally ) enough plasticity and toughness. The concentration of alloy element of this kind of steel is quite high, mainly are corrosion resistant steel, heat resistant steel, wear resistant steel, and other special steels of physical and chemical properties. Alloy structural steel has preferable mechanical property than that of carbon structural steel, high performance of heat treatment especially.
Official Test Certificate: issued by TUV - SGS - CNAS
