SA387Gr5Cl2 steel material is suitable for refining and gas treatment in hydrogenation and conversion equipment at high temperature. The maximum thickness of A572 grade 55 CS steel carbon plate, SA387Gr5Cl2 steel plate can reach 250mm According to different thickness and impact requirements, the heat treatment of SA387Gr5Cl2 steel plate is normalizing plus tempering or normalizing plus rapid cooling plus tempering By using special smelting method, the content of phosphorus is reduced so that sa387 has high brittleness resistance and good impact toughness at low temperature,A572 grade 55 CS steel carbon plate.
Bridge steel is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges,A572 grade 55 CS steel carbon plate.
A572 grade 55 CS steel carbon plate,The preparation of 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 centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
SA516Gr70 steel chemical composition (%):C≤030, Mn: 079-130, P≤0035, S: ≤0035, Si: 013-045 ASME SA516Gr70 material is a carbon steel grade for medium and low temperature pressure vessels In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ SA516Gr70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels,A572 grade 55 CS steel carbon plate.
A572 grade 55 CS steel carbon plate,After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.A572 grade 55 CS steel carbon plate
