GNEE sells more than 1,500 tons of seamless and welded steel pipes to various engineering industries every year. Our goal is to ensure that our customers have the highest expectations for the delivery and product quality of JIS G3445 STKM 11A Carbon Steel Structural Pipe.
JIS G3445 STKM11A cold-drawn steel pipe contains a certain amount of silicon and manganese in addition to carbon elements and deoxidation. In addition to alloying elements, no other alloying elements (except residual elements) are contained. This type of steel must ensure both chemical composition and mechanical properties.
JIS G3445 STKM11A cold-drawn pipe involves pulling the pipe through a die to reduce its diameter and increase its length, thereby improving dimensional accuracy and surface finish. STKM11A seamless cold-drawn pipe is known for its high precision and excellent mechanical properties.
