Finished high precision cold drawn precision tubes, good surface quality. 4 Steel Cross area more complex. 5. steel pipe superior performance, the metal is relatively dense. 3. cold drawn finished high accuracy, good surface quality. 4 Steel Cross area more complex. 5. steel pipe superior performance, the metal is relatively dense. Precision steel calculation formula :: [(OD - Wall Thickness) * thickness] * 0.02466 = kg / m (weight per meter) Shandong Huafeng Pipe Co., Ltd. is a professional seamless steel pipe, steel pipe, precision steel tubes, shaped pipe, welded pipe production and sales of the modern enterprise. Precision steel precision tubes heat treatment process 40cr price, vacuum annealing quality spring steel, tool steel, precision steel wire, stainless steel and titanium alloy products, wood, bright annealing can be employed for the vacuum treatment. Annealing temperature, the lower precision tube manufacturer, the higher the degree of vacuum is required. To prevent chromium evaporation and accelerated thermal conduction, generally use the carrier gas heating (thermal) method, and attention should not be used for stainless steel and titanium nitrogen and argon should be used.
