With over 20 years' experience, our factory offer high quality products made in China with competitive price. Welcome to contact us for wholesale service.
Product Information Description The alloy structural steels are 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. Application The alloy structural steels are widely used in the filed of ship, vehicle, airplane, guided missile, weapons, railway, bridges, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on. Quality Standard EN 10250 Open steel die forgings for general engineering purposes. Alloy special steels
