Kalikund Steel & Engg. Co. is a renowned fabricator and stockiest of 4130 Pipe Fittings & Flanges in Beijing, China. 4130 is an extensively used common alloy steel. 4130 steel is chromium-molybdenum alloy steel with minimum carbon content. It has a density of 7.85 g/cm3 (0.284 lb. /in3) and is heat-treated for hardness.
It’s outstanding welding steel that can be welded using any commercial method and can be machined in its normal state. Implementations for 4130 steel alloy consists of pressurized gas cylinders, firearm parts, and clutch components, all of which needs good strength and precision while being light and easy to work on.
As AISI 4130 is a steel grade with great formability and ductility, it can be used to make a variety of AISI 4130 Fittings, including straight tees, reducing tees, long-radius elbows, 3R elbows, caps, and reducers. This low alloy steel, which has a nominal carbon content of 0.3 percent, a chromium content of 1%, and molybdenum content of 0.2 percent, is also generally used in petroleum industries.
This minimum alloy steel’s content is a through-hardening alloy with remarkable adaptability in the annealed state. Since chromium and molybdenum are used as reinforcing factors in this low alloyed steel, the AISI 4130 Pipe Fittings & Flanges have good machinability, strength, fracture toughness, and long life.
Since these fittings have a low carbon content, they are easy to weld. In reality, the AISI 4130 Buttweld Pipe Fittings and Flanges can be welded using any commercial shop practices due to its unique welding characteristics. Furthermore, grade AISI 4130 can be machined smoothly in its standard or tempered form.
For 4130 Pipe Fittings & Flanges, Kalikund Steel & Engg. Co. offers delivery conditions such as Annealed, Normalized, Stress Relieved, Quenched, and Tempered. We offer an extensive range of 4130 Pipes Fittings & Flanges. Kalikund Steel & Engg. Co has established long-term relationships with mega international producers and distributors.
