MD Exports LLP manufactures AISI 4130 6B and 6BX flanges in various sizes & pressure ratings as per API 6A. Most common material is low alloy steel AISI 4130 or AISI 8630. AISI 410 or UNS 31803 are used for some of the critical services. Application of CRA (AISI 316L or Nickel alloy 625) enhance the corrosion resistance ability of ring groove, thus enhancing the product life.

AISI 4130 6B flanges:

AISI 4130 6B flanges are ring joint type and are not designed for face-to-face make-up. Bolting force acts on the metallic ring gasket. AISI 4130 6B flanges are of through bolted or studded design. R or RX are ring groove type.

Types of AISI 4130 6B flanges are:

AISI 4130 6BX flanges:

AISI 4130 6BX flanges are ring joint type and has raised face. Joining make-up bolting force acts on the raised face of the flange when the gasket is properly seated. This support prevents damage to the flange or gasket from excessive bolt torque. Therefore 6BX connection has raised face. Type AISI 4130 6BX flanges are of through bolted or studded design. Face-to-face contact is not necessary for the proper functioning of the AISI 4130 6BX flange. AISI 4130 6BX flanges have BX ring gasket grove.

Types of AISI 4130 6BX flanges are:

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.
