How Much Is a Ton Of A387 grade 11 class 2 pressure vessel steel sheet?

Features of Q235NHA sheet:Q235NH steel sheet has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, and labor and energy saving. It has a long service life when used in harsh environments. It has a protective rust layer to resist atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere.

Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.

Quenching Improve the hardness of A387 grade 11 class 2 pressure vessel steel sheet steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of A387 grade 11 class 2 pressure vessel steel sheet steel and comprehensive mechanical properties.
