JIS G3445 STKM14B Carbon Steel Pipe
GNEE's JIS G3445 STKM14B is produced using various manufacturing processes, including hot or cold working, and then the pipe is subjected to various tests, such as flattening test, water pressure test or non-destructive electrical test, to ensure that the specified requirements are met.
STKM14A seamless carbon steel pipe is a structural steel with chemical composition including carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S) and other elements. According to JIS G 3445 standard, the density of STKM14A steel pipe is 7.85g/cm³.
Because of good tensile strength and toughness, JIS G3445 STKM14B seamless steel pipe is widely used in the design of various automotive sites, hydraulic equipment and precision machinery.
