What is the JIS SM520B plates continuous casting

In recent years, in line with the development trend of iron and JIS SM520B plates steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which JIS SM520B plates are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

S355J2 is a low-alloy high-strength steel, which can be treated to meet the requirements of Z-15, Z-25, Z-35 and level I, level II and level III flaw detection.The extension grades of S355J2 are S355J2, S355J2-Z35 and S355J2 + N-Z35, JIS SM520B plates. On the basis of S355J2, S355J2-Z35 increases the requirement of S355J2 steel plate thickness direction performance, namely Z-direction performance. S355J2 + N-Z35 is a heat treatment process which increases Z-direction properties and normalizing rolling (or normalizing).

15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel JIS SM520B plates is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.

The common delivery status of JIS SM520B plates, SA516 Gr 70 plate is as follows: 1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point. 2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air). 3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly. 4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.
