AISI 4130 low alloy steel containing nominally 0.3% Carbon, 1% Chromium and 0.2% Molybdenum 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.
