Grade 4130 is typically used for pressure containing applications such as valve bodies or pipework, also used for valve gates and stems.
Very good weldability, and so may be readily welded to itself or weld inlayed. However there have been recent concerns on using the grade for buttered connections.
The grade has a typical ruling section of around 4 inches (at 75 Ksi) depending on the composition and analysis, and it is critical that the hardenability of the grade must be taken into account when designing and selecting it for specific equipment.
