Alloy Steel AISI 4140 flanges are made from low alloy steel. This alloy is a combination of chromium and molybdenum with strengthening agents and a nominal carbon content of 0.30%. 


It has excellent fusion weldability, is abrasion and wear resistance, and can be hardened in the heat treatment process. Typical applications for this alloy include structural, aircraft engine mounts, and tubing.


Alloy Steel AISI 4140 flanges are a variety of shapes and sizes. Each flange is marked with the name of the manufacturer, size, bore, and material. Some are also marked with a heat number if the customer requests one. 


AISI 4140 flanges are a popular choice for oil and gas extraction applications. Jaydeep Steels offers an extensive range of AISI 4140 flanges to suit your needs.


AISI 4140 flanges are manufactured with different face types. For example, ring joint flanges are welded to two ends of a pipe. This makes them wear-resistant and slip-on flanges. The most common ASTM A182 F91 flange type is a ring joint flange. These flanges have a welded joint in order to resist wear.


The most important aspect of alloy steel AISI 4140 flanges is their tensile strength. Although they may appear stiff and brittle, they are actually quite tough. The alloys' strength makes them difficult to work with, so a forged flange requires a higher amount of force to form it. It is also possible to heat treat alloy steel AISI 4140 flanges to provide even more advantages.
