AISI 4037 4340 large diameter thick wall stainless steel pipe

The AISI stands for American Iron and Steel Institute and The '41' indicates low alloy steel containing chromium and molybdenum and the ‘30’ indicates a carbon content of 0.30 percent in 4130 material. Alloy steels are designated by AISI four-digit numbers. These alloys are highly reactive to mechanical and heat treatments than carbon steels. They contain different types of steels with compositions exceeding the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va in the carbon steels.

PRODUCT DETAILS

Product Description

The AISI stands for American Iron and Steel Institute and The '41' indicates low alloy steel containing chromium and molybdenum and the ‘30’ indicates a carbon content of 0.30 percent in 4130 material. Alloy steels are designated by AISI four-digit numbers. These alloys are highly reactive to mechanical and heat treatments than carbon steels. They contain different types of steels with compositions exceeding the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va in the carbon steels.

The important part of AISI 4130 steel is that it contains chromium and molybdenum as strengthening agents. The amount of carbon content is low, and hence it can be welded with no trouble. Properties of Alloy steels (including 4130 material) vary over carbon steels due to constituents such as boron, carbon, chromium, manganese, molybdenum, silicon, and vanadium and having chromium contents less than 4%. The major alloying elements added to AISI 4130 are:

  • Manganese content >1.65%
  • Silicon content >0.5%
  • Copper content >0.6%

4130 chrome-moly offers a good blend of strength, weight, and ductility for many motorsports and aerospace applications. In the case of TIG tubing welding Preheat is not necessary for tubing under 120" thickness. We can make use of a TIG machine with high frequency starting to eliminate arc strikes. It’s a little slower when TIG welding to slow down the cooling rate and avoid any chance of the welded area cooling too fast. Applications of AISI 4130 include high-pressure pipe include Aircraft engine mounts, Welded tubing. It is often used for high-end bicycle frames and race-car roll cages due to its high tensile strength, malleability, and easy weldability.
