raex 500 welding top manufacturer in Sri Lanka
The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for raex 500 welding.
After tempering at 500-650 ℃, the NM400 wear-resistant plate has tempered sorbite structure, which has high comprehensive mechanical properties of strength and toughness. Quenching and tempering treatment is mainly used for all kinds of important structural parts, so that the strength, plasticity and toughness of wear-resistant plate, raex 500 welding can reach the appropriate match, and have good comprehensive mechanical properties.
