What is the BBNSteel company astm a516 grade 70 thickness stock list

In production and operation, the company always attaches great importance to product astm a516 grade 70 thickness quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market astm a516 grade 70 thickness. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

Normalizing process of S355J2 steel plate: normalize the S355J2 steel plate in the bottom furnace, normalizing temperature is 880-910℃, holding time is 1.8-2.2min/mm, that is to get the required S355J2 + N steel plate. 355j2 + N steel plate is mainly used in large machinery manufacturing, equipment base, large welded steel structure, construction, bridge and other fields. With the continuous development of economy and the large-scale demand of equipment, the demand of ultra thick astm a516 grade 70 thickness, S355J2 + N steel plate is increasing gradually.

Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. astm a516 grade 70 thickness, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, astm a516 grade 70 thickness, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

astm a516 grade 70 thickness, Q345R pressure vessel steel is an ordinary low alloy steel, which is commonly used for boiler and pressure vessels. The delivery status of Q345R pressure vessel steel is hot rolling or normalizing. The properties of Q345R pressure vessel steel are similar to those of Q345 steel (16Mn). The yield strength of 16mm steel plate is greater than 345 Mpa, the tensile strength is 510-640 Mpa, the elongation is more than 21%, and the zero degree V-shaped impact energy is greater than 34J. The process reference standard of Q345R pressure vessel steel is GB713.
