Requirements for chemical composition of EN S355M steel supplier

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. EN S355M steel supplier Heat treatment process refers to the ability to change the microstructure and properties of EN S355M steel supplier after heat treatment, including hardenability, hardenability, temper brittleness, etc.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the EN S355M steel supplier steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.
