Description
4130 mod grade steel is a chromium-molybdenum steel used widely for wellhead applications.
It can be quenched and tempered to high strengths, however hardenability limitations prevent through hardening above approximately 5”.
This grade also offers good weldability and machinability, and has relatively low cost. It is often clad with Ni alloy 625 at seal joints to prevent crevice corrosion.
Typical applications of 4130 mod grade steel
