AISI 4130 Flanges are available in several forms. These types include AISI 4130 Slip On Flanges, UNS G41300 Flanges, Ring Joint Flanges, and Weld Neck Flanges. If you are looking to purchase AISI 4130 Flanges, you'll want to consider contacting a supplier in India. They offer many different sizes, pressure ratings, and types of flanges.


If you're looking for a high-quality AISI 4130 flange, you've come to the right place. Steel Mart India is an ISO certified manufacturer of AISI 4130 Flanges in Mumbai and Dubai. We stock AISI 4130 Reducing Flange, Slip on Raised Flange, AISI UNS G41300 Flange, and AISI UNS G41300 Fflange.


AISI 4130 flanges contain about 97% iron, plus some silicon, manganese, and phosphorus. This high-quality alloy steel also offers reasonable strength and good weldability. 


This steel grade is widely used in offshore and onshore applications, as well as electric and natural gas pipelines. The properties of ASTM / ASME SB 564 / 160 / 472 ASTM SB564 flanges make them the best choice for high-pressure applications.


The most common process for machining AISI 4130 flanges is austenitizing. This process converts micro constituents into austenite. The exact temperature range varies, depending on chemical composition, section size, and cooling method. 


Once a piece is forged, it must undergo an austenitizing process to achieve the desired level of strength. If you want a flange to be forged, you need to heat it up to a minimum of 1600 F.


AISI 4130 is one of the most common grades of steel used in aerospace, oil and gas, agriculture, and automotive applications. The alloy is also produced in a lighter gauge. 


This lighter gauge 4130 Forging Pipe Flange is ideal for racing purposes. This grade is also great for manufacturing aircraft engine mounts. And as a bonus, it has a higher strength-to-weight ratio than ordinary carbon steel.


Alloy Steel AISI 4130 is often exported to foreign countries. They are commonly found in Malaysia, Singapore, Hong Kong, Indonesia, and Taiwan. However, they're also used in Afghanistan, Belarus, and Bahrain.
