Carbon steel is widely applied for production of pipe fittings because of its prominent advantages such as low cost, great processability and easiness of smelting, even though it does have some disadvantages. For example, it could not withstand the corrosion by air, acid, alkali and sodium. Below Ductile-to-Brittle Transition Temperature, it will become brittle. In addition, it will be magnetized when in magnetic fields.
Production Process
Generally, carbon steel type and production process selected for manufacturing of carbon steel pipe fittings are determined by the outer diameter and wall thickness of the finished pipe fittings required. Please refer to the situations listed below.

Once formed, carbon steel pipe fittings will first go through different heat treatment processes based on the raw material grade. Then non-destructive testing will be conducted for the surface, which includes magnetic powder detection and dye penetration inspection. If qualified, the surface will go through shot blasting process and then could be imprinted and packaged according to customers’ requirements.
