nm500 steel equivalent plate specification

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, NM500 steel equivalent 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. NM500 steel equivalent ASTM 572 steel I can be used in other grades, such as 42, 55 and 60.

Compared with carbon steel, alloy steel has higher strength, better heat resistance, better low temperature resistance, better corrosion resistance and other advantages. Some of its work environment can not be adapted by carbon steel. Therefore, alloy steel is a common and important material in pressure pipeline. Low alloy steel, NM500 steel equivalent quenched and tempered steel, stainless steel, heat-resistant steel and low temperature steel are commonly used in pressure pipes.

Tempering the important NM500 steel equivalent 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 NM500 steel equivalent strength, plasticity and toughness.
