carbon steel sa573 Grade 70 for boiler supporting parts

ASTM A633 material is particularly suited for service at low ambient temperatures and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired. carbon steel sa573 Grade 70, A633 Grade E high-strength low-alloy structural steel provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.

A Uganda client purchased 2100 tons SG255 gas cylinder steel coils in 2018. It is the first company in Uganda to provide re-furbishing, re-certification and manufacturing of new lpg cylinders. They have regular demands for sg255 coils carbon steel sa573 Grade 70 every 3 months. Limited by inland location, we can only ship container to mombasa, and then transfer to kampala. OurJISG3116 SG255 steel product is grade for gas cylinder steel with the tensile strength of 400MPa and the yield strength of 255MPa.

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 carbon steel sa573 Grade 70 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.
