4130 mod - 1% Chromium-Molybdenum Through Hardening Steel
Surcharge Information
Due to the UK’s mostly commonly recognised surcharge mechanism no longer being openly published to the UK market we are unable to provide specific surcharge information on our website at this stage.
We are currently working with our suppliers to establish alternative mechanisms in order to provide a comprehensive and transparent view of global surcharge variations.
Look out for our improved surcharge pages appearing in the coming weeks.
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.
Size Range
32mm - 240mm Dia
