Kalikund Steel & Engg. Co. is a renowned provider of 4130 Pipe Fittings & Flanges in Auckland, New Zealand. 4130 is an extensively used general-purpose 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 undergoes heat treatment for firmness.

It’s outstanding welding steel that can be welded using any commercial process and can be machined in its normal form. Applications for 4130 steel alloy consists of pressurized gas cylinders, firearm parts, and clutch components, all of which needs high 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 manufacture a variety of AISI 4130 Fittings, that consists of 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 commonly used in petroleum projects.

This low alloy steel’s content is a through-hardening alloy with excellent malleability in the annealed state. Since chromium and molybdenum are used as reinforcing agents in this low alloyed steel, the AISI 4130 Pipe Fittings & Flanges have the best 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 extraordinary welding characteristics. Furthermore, grade AISI 4130 can be machined easily in its normalized or tempered state.
