SA572 grade 42 carbon steel plate sheet name in different countries

S355J2 is a European standard low alloy high strength structural steel grade, equivalent to Q345D. Because of its good impact toughness and welding performance, S355J2 steel plate is widely used in bridges, ships, power plant equipment, hoisting and transportation machinery, machinery manufacturing and other engineering and welding structures that bear high loads. S355J2 steel plate delivery status: hot rolled delivery, the SA572 grade 42 carbon steel plate sheet specific delivery status should be indicated in the contract.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from SA572 grade 42 carbon steel plate sheet. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium SA572 grade 42 carbon steel plate sheet carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some SA572 grade 42 carbon steel plate sheet alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
