Stainless steel and heat-resistant steel heat treatment operations
Cleaning: 1. The workpieces and fixtures should be cleaned of oil, residual salt, paint, and other foreign matter before heat treatment. 2. The fixture used for the first time in the vacuum furnace should be degassed and purified in advance at a vacuum level not lower than tha...Read more -
Duplex stainless steel pipe cold working process
1. The yield strength of duplex stainless steel is twice as high as that of austenitic stainless steel. The deformation amount should be smaller than that of the latter. Appropriate speed and feed rate must be selected during cold rolling to minimize uneven longitudinal wall t...Read more -
How to check the quality of large-diameter thin-walled steel pipes
1. Generally, large-diameter thin-walled steel pipes are used for the transportation of generally lower-pressure fluids such as water, gas, air, oil, and heating steam. 2. Ordinary carbon steel wire casing (GB3640-88) is a steel pipe used to protect wires in electrical install...Read more -
Large diameter straight seam steel pipe rust removal method and production process
Large-diameter straight seam welded pipe is a general name, produced with steel strips, and pipes straight seam welded by high-frequency welding equipment are called straight seam welded pipes. (It is named because the welding joint of the steel pipe forms a straight line). Am...Read more -
