What is astm a537 class 1 equivalent used for?

The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has astm a537 class 1 equivalent strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and astm a537 class 1 equivalent pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.

astm a537 class 1 equivalent, 40Cr material is a common machinery manufacturing steel under GB/T 3077-2015 standard. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28-60mm during water quenching and Ф15-40mm during oil quenching. The cutting performance is better, when the hardness is HB174 -229, the relative cutting workability is 60%.

astm a537 class 1 equivalent, Q345D seamless pipe is low-alloy high-strength structural steel. It is named as low-alloy because of a small amount of alloy elements in the steel. Q345D seamless pipe is mainly used for construction and engineering structures. The carbon content of Q345D seamless pipe is ≤ 0.18%. Due to the effect of alloy elements, the yield strength of Q345D seamless pipe is 25% - 150% higher than that of carbon structural steel pipe with the same carbon content. Q345D seamless pipe can reduce the weight of steel structure, save steel products and effectively extend the service life of steel structure.

The effect of alloy elements of astm a537 class 1 equivalent, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.

ASTM a588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the astm a537 class 1 equivalent yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 astm a537 class 1 equivalent has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.
