YanTai XinPeng Steel Pipe Co.,Ltd located in Yantai, a beautiful coastal city in Jiaodong Peninsula, our company is in the (APEC) Science & Technology Industrial Park, urban area of Yantai, with convenient transportation. Established in December 1992, with registered capital of 5 million yuan .
Our company mainly produces various specifications of cold drawn,rolled precision steel tube,hydraulic cylinder tube and SRB Tube, which are widely used in such industries as hydro-cylinder, automobile, engineering machinery, textile machinery, printing machinery, oil drilling, etc. Our company is also the distributor of several domestic well-known steel tube plants in Shandong, and mainly distributes seamless steel tubes of all kinds of materials.
ASTM A53 seamless steel tube refers to the American standard A53-f corresponds to the China q235 material, a53-a corresponds to the China 10# material, a53-b corresponds to the China 20# material.
20 of steel 20 refers to the carbon content of 0.2%, which belongs to low carbon steel.Steel can be divided into low carbon steel, medium carbon steel and high carbon steel.
Carbon content: low carbon steel is generally less than 0.25%;Medium carbon steel is generally between 0.25 and 0.60%;High carbon steel is generally greater than 0.60%.
In addition to contain carbon (C) elements in steel and for DNA containing a certain amount of silicon (Si) (generally no more than 0.40%), manganese (Mn), high (generally no more than 0.80%, to 1.20%) alloy elements, excluding other alloying elements (except for residual element).
