What is ASTM equivalent of q355nh machinability and their difference

The company mainly supplies q355nh machinability steel materials, and has a large amount of inventory all year round. We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of q355nh machinability steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.

The commonly q355nh machinability steels used to manufacture pressure parts of boilers mainly include low carbon steel, low alloy structural steel, low alloy heat-resistant steel, austenitic stainless heat-resistant steel and martensitic heat-resistant steel, etc. According to profiles, these boiler steels can be divided into boiler steel plates and boiler steel pipes. Our main q355nh machinability boiler steel materials are as follows: A516 Gr 70, A537 class 1 , 16Mo3, Q345R, A204 grade B, A285C, ASTM A387, P355GH and so on.

The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe q355nh machinability is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as q355nh machinability. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.

q355nh machinability product plate specification range:
Thickness 3-150mm
Width 1500-4020mm
Length 4000mm-17000mm
Heat treatment: annealing, or normalizing and tempering

The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide q355nh machinability cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about q355nh machinability ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.
