Product Description
The steel tubes under JIS G 3454/3456 are carbon steel tubes suitable for welding and threading, and can be formed by bending, crimping and similar processes, and are also suitable for welding operations. The material grades (chemical composition) of welded steel pipes are STPG370 and STPG410 of JIS G 3454 and STPT370 and STPT410 of JIS G 3456, and they are manufactured by resistance welding process.
