316 austenitic stainless steel characteristics: due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good. KB grab dredger steel, 316 ss plate and sheet can be used under harsh conditions. 316 stainless steel has excellent work hardening (non-magnetic); excellent high temperature strength; The solid solution state is non-magnetic; the appearance of cold-rolled products is good and beautiful. Compared with 304 stainless steel, the 316 stainless steel price is higher.
Spring steel has good fatigue strength and can be restored to its original shape after repeated use without deformation. Because the spring has good ductility, it can be changed back to its original state no matter how long it is stretched. Spring steel has good elasticity. In addition to being made into springs, spring steel can also be processed into swords, which requires good elasticity also. KB grab dredger steel, Spring steel has good tensile strength and can be restored without breaking under the limit of being stretched.
Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce KB grab dredger steel, hot-rolled seamless steel tube by continuous rolling mill.
