It can provide accurate, timely and high-quality support and service for users, which is well received by users.

Special boiler steel is derived from carbon structural steel, SA573 Grade 58 structural steel. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

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. SA573 Grade 58 structural steel Heat treatment process refers to the ability to change the microstructure and properties of SA573 Grade 58 structural steel after heat treatment, including hardenability, hardenability, temper brittleness, etc.

Our client purchase more than 900 tons pipe SA573 Grade 58 structural steel from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.
