A517 Grade Q steel is a low-alloy pressure vessel grade rolled steel plate that conforms to A20 manufacturing specifications; in an open-hearth under oxygen or via electric arc production. These plates have a maximum thickness of 32mm EN 10149-2 equivalent indian standard and must be subjected to robust heat analysis to verify its elemental composition. Process managers must carefully control the levels of carbon, manganese, phosphorous, sulfur, silicon, chromium, molybdenum, boron, vanadium, and titanium in order to guarantee compliance – thus performance.

en 10149-2 equivalent indian standard, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

The preparation of en 10149-2 equivalent indian standard galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for en 10149-2 equivalent indian standard centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
