Welcome to BBN High Strength Steels Factory
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 EN 10025-6 high strength steel S500Q, S355J2 + N steel plate is increasing gradually.
EN 10025-6 high strength steel S500Q, 09CuPCrNi-A corrosion-resistant steel plate belongs to ordinary low-alloy steel and steel for engineering structures; it is a high-strength corrosion-resistant steel plate. The combination of Cu and P can resist atmospheric corrosion. In addition, there are Cr and Ni, both of which are used in stainless steel. 09CuPCrNi-A corrosion-resistant steel plate is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.
Tempering the important EN 10025-6 high strength steel S500Q welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve EN 10025-6 high strength steel S500Q strength, plasticity and toughness.
If you want to get the ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel price, please do not hesitate to contact us. Any need in EN 10025-6 high strength steel S500Q ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates Chemical Composition and Mechanical Properties, please feel free to contact us by email or calling to us
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
