Do you know the NM400 material meaningheat treatment?

A572-50 steel I-beam is widely used in construction and architectural applications because it can provide more strength unit weight. The low content of niobium, vanadium and other alloy elements optimize its strength and atmospheric corrosion performance. Because of its high strength of 50000 Ksi yield strength, NM400 material meaning a572-50 steel I-section steel is more and more replacing ordinary carbon steel beams such as A36, and A36 section steel needs to be thickened to meet the strength requirements. NM400 material meaning ASTM 572 steel I can be used in other grades, such as 42, 55 and 60.

Special boiler steel is derived from carbon structural steel, NM400 material meaning. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest NM400 material meaning processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain NM400 material meaning by rolling method.

We are engaged in NM400 material meaning corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, NM400 material meaning ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
