Commonly used material
Commonly used materials are 10#, 20#, 35#, 45#, 20Cr, 40Cr, 20CrMo, 16Mn, 27SIMN, 304, 201, 310S, high quality carbon structural steel.
Precision tube characteristics
The characteristics of
1. Smaller outside diameter.
2. High precision can do small batch production.
3. Cold-drawn products have high precision and good surface quality.
4. The cross area of steel pipe is more complex.
5. The performance of steel pipe is superior, and the metal is dense.
The inner and outer walls of the precision steel pipe have no oxide layer, and can be installed directly in the hydraulic system.
Precision steel tube is refers to the steel tube of high accuracy of steel tube, wall thickness and inside and outside diameter can master the tolerance range within 10 silk, this kind of steel tube and ordinary hot-rolled seamless steel tubes and cold drawn seamless steel tube outer surface has the difference, precision steel tube outer and inner diameter is bright and clean smooth surface, color and stainless steel, because of manufacturing all internal and external surface with a layer of oil.
