SA516 gr.60 boiler plates are primarily intended for use by pressure vessel fabricators and manufacturers. And, physical and chemical characteristics of the boiler quality plates make these a popular choice in the industries. SA516 gr.60 boiler steel plates are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built. Also, these plates a537 class 1 hardness are repellent to corrosion and therefore is long-lasting and can also be used in different environments for a long time without any deterioration.

Corrosion resistance mechanism of a537 class 1 hardness, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.

S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. a537 class 1 hardness, S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate, a537 class 1 hardness.
