Cold Rolled Precision Seamless Steel Pipe Hot Rolling, Hot Extrusion And Cold Drawing Stainless Steel Pipe
Precision seamless steel pipe is a kind of high-precision steel pipe after cold rolling or cold drawing;
Full name: cold rolled precision seamless steel pipe.
The advantages :
1. No oxide layer on the inner and outer walls of precision seamless steel pipe,
2. No leakage under high pressure, high precision, high finish,
3. No deformation in cold bending, flaring, flattening and no cracks,
Applications:
Pneumatic or hydraulic components, such as air cylinder or oil cylinder.
The chemical composition of precision seamless steel pipe includes :
Carbon C, Silicon Si, Manganese Mn, Sulfur S, Phosphorus P and Chromium CR.
Features of precision stainless steel seamless pipe:
1. The thicker the wall thickness of the product, the more economical and practical it will be.
The thinner the wall thickness, the higher its processing cost will be;
2. The process of the product determines its limited performance.
Generally, the precision of seamless steel pipe is low:
uneven wall thickness, low brightness on the inner and outer surface of the pipe,
high sizing cost, and pockmarks and black spots on the inner and outer surface are not easy to remove;
3. Its detection and shaping must be processed offline.
Therefore, it embodies its advantages in high pressure, high strength and mechanical structure materials.
Types of precision stainless steel pipes:
The rolling methods include hot rolling, hot extrusion and cold drawing (rolling) stainless steel pipe.
According to different metallographic structure of stainless steel,
it is divided into semi Ferritic and semi martensitic stainless steel pipe,
martensitic stainless steel pipe, austenitic ferritic stainless steel pipe, etc.
