ASTM A513/A513M Grade 1025 Introduce
The two main types of steel tubing commonly used in construction are seamless and electric-resistance-welded (ERW). Seamless steel tube is produced by continuously extruding hot steel over a mandrel. ERW steel tube is produced by rolling a sheet of high-temperature steel between two copper-clad plates and then welding it along the sides.
Smelting temperature:1692°C - 1214°C
Application:Resistance welding carbon steel and alloy steel mechanical steel pipe
