Seamless Mechanical Tubing Steel Pipe S45C S35C
S35C S45C Carbon Steel Seamless Tubes are widely used in mechanical equipment manufacturing, automotive parts manufacturing, and other finishing industries.
S35C S45C Carbon Steel Seamless Tubes for machining or structural use (hereafter referred to as steel tubes) are manufactured by cold rolled or cold drawn. This material applies to steel products with a uniform cross-section, generally supplied for use after a further process such as cold working, cutting, and heat treatment.
