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.

AISI 4130 low alloy steel containing nominally 0.3% Carbon, 1% Chromium and 0.2% Molybenum is widely used in oil patch applications. It is similar to 4140 which has a higher carbon level giving 4130 improved weldability, at the expense of through thickness strength.

The hardenability limitations of this grade (depth to which it will harden / obtain the specified mechanical properties after heat treatment) must always be taken into account when designing and selecting equipment.

Primarily manufactured in:

  • Dubai, UAE
  • Edmonton, Canada
  • Houston, Texas
  • Sheffield, England
  • Singapore

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.
