MD Exports LLP takes immense pleasure in Introducing itself as a Stockiest & Exporter of Alloy Steel AISI 4130 Forged Flanges, AISI 4130 Flanges, API Flanges & AISI 4130 Fittings. MD Exports LLP regularly supplies AISI 4130 Forged Flanges to core industries such as refineries, chemical & petrochemical, oil & Gas, Water treatment plant, power plants, off-shore, ship building, EPC & other Engineering company. We can supply AISI 4130 Forged Flanges & LONG SWEEP MANIFOLD REINFORCED FITTINGS Suitable for 5000, 10000 & 15000PSI Applications. We have ready stock of 4130 Grade Fittings, Tees & Olets (Origin America / German) etc. We also stock 10,000 psi API6BX blind and weld neck flanges in 4130 (or 410 stainless) grade in 60K and 75K.

API Licensed Manufacturers usually use 4130 for all of their 6BX connectors especially weld neck connectors (flanges and hubs). Steels other than 4130 that manufacturers may use, include 4140, 8630, and 410 “Stainless Steel.” All of these materials prove more difficult than 4130 to weld, they almost can’t be welded satisfactorily in the field. Of the commonly available low alloy steels, AISI 4130 Forged Flanges & 4130 has the best weldability.

AISI 4130 Alloy Steel (UNS G41300)

Alloy steels are designated by AISI four-digit numbers. They are more responsive to mechanical and heat treatments than carbon steels. They comprise different types of steels with compositions which exceed the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va in the carbon steels. 

AISI 4130 alloy steel contains chromium and molybdenum as strengthening agents. It has low carbon content, and hence it can be welded easily. The datasheet given below provides more details about AISI 4130 alloy steel. 

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels.

Grades shown in the above list with prefix letter E are normally made only by the basic electric furnace process. All others are normally manufactured by the basic open hearth or basic oxygen processes but may be manufactured by the basic electric furnace process with adjustments in phosphorus and sulphur.
