Product introduction. SA516 is a carbon steel plate grade utilized primarily in welded pressure vessels for moderate to lower temperature service. This material is produced in grades 55, 60, 65 and 70. This material is also offered in the normalized condition where improved notch toughness is required.
Grades and Materials for Boiler and Pressure Vessel Steel Ordinary carbon steel only contains carbon as the main element in influence steel mechanical properties, in fact limited amount of manganese and silicon also exist in carbon steel plate and pipe products, and as the raw material contains elements of small quantities, such as nickel, chromium, aluminium, molybdenum and copper, and the bad impurities phosphorous and sulphur.
JIS G3103 standard provides the boiler and pressure vessel with carbon steel and molybdenum alloy steel plate delivery technical conditions.JIS G3103 standsrd main steel grade:SB410,SB450,SB480,SB450M,SB480Mspv 450 boiler steel plate, spv235 steel sheet, spv355 Our jis g3115 boiler and pressure vessel steel plates mainly used in oil and gas companies, chemical industry, power plants for making the Reactor, Heat Exchanger, Separator, Spherical Tanks, Tanks of oil gas, Nuclear reactor pressure shell, High-pressure water pipe, Turbin shell and other equipments.
