27simn Honing Cylinder Tube
GNEE sells more than 1,500 tons of seamless and welded steel tubes 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 27SiMn Seamless Cold Drawn Steel Tube.
For 27SiMn honed steel tube, 27 represents the carbon content in this tube, and the following Si and Mn represent the limit of Si and Mn content in this material, which improves the wear resistance and abrasion resistance of the steel, thereby improving the sealing and service life of 27SiMn cylinder tube.
In addition, 27simn seamless honed cylinder tube can be formed by rolling, and a cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby avoiding burns caused by grinding.
