Is sb450m steel specification used for high temperature and high pressure boiler

sb450m steel specification product plate production process:Raw materials (scrap steel, pig iron and molten iron) → electric furnace (100 tons electric arc furnace smelting) → converter → LF furnace molten steel refining treatment → VD or VOD furnace molten steel vacuum treatment → die casting (various key die casting lines) or continuous casting (large Slab caster) (50 tons of slab electroslag furnace for remelting a steel ingot) → heating (continuous furnace and soaking furnace) → steel plate rolling (4100 and 4200mm rolling mills) → steel plate heat treatment (normalizing and tempering) Quality) →Steel plate cutting inspection→Inspection

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel sb450m steel specification plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.

SA516Gr70 steelmaking process: the steel should be killed steel and meet the requirements of A20 / A20M standard fine austenite grain size. Related steel grades are: SA515GR60, SA515GR70, SA516GR60, SA516GR70, SA516GR60N, SA516GR70N, sb450m steel specification.Chemical composition analysis of SA516Gr70: C: no more than 0.3, Mn: 0.79-1.30, P: no more than 0.035, S: no more than 0.035, Si: 0.13-0.45.

The metal properties and mechanical properties of sb450m steel specification low-carbon steel sheets are divided into boiling steel and aluminum-killed steel according to the different deoxidation methods used in the steelmaking process (melting, ingot casting and plate solidification).
