Welded steel tube delivery condition +C +N for producing camshafts offers enhanced strength and machinability. This specialized form of steel arrives normalized and with added carbon and nitrogen content, providing improved durability and wear resistance crucial for camshaft applications. It ensures precise performance under demanding conditions, a key requirement for automotive components.
According to EN10305-2 standard, cold drawn on ERW tubes, making the tubes have high strength, high quality, and to be seamless.
