AISI 4140 is a low alloy steel that contains chromium, molybdenum, and manganese. It is commonly used in applications such as structural tubing, axles, shafts, and gears.

Flanges made from AISI 4140 steel are typically used in high-pressure applications that require high strength and durability. These flanges are commonly used in the oil and gas industry, as well as in other industries such as aerospace, automotive, and manufacturing.

AISI 4140 flanges come in a variety of sizes and types, including weld neck, slip-on, blind, and threaded. They can also be custom-made to meet specific requirements. The selection of flange type and size will depend on the application and the specifications of the project.

It is important to note that AISI 4140 steel should be heat-treated before use to maximize its strength and toughness. This process involves heating the steel to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a specific rate. The heat treatment process can significantly improve the properties of the steel, making it more suitable for high-pressure applications.
