Re: [MW:24212] Procedure qualification for AISI 4130 (Cr-Mo forging)

Hi,

To my understanding this material is used most case in construction of valves in the area of upstream segment - drilling and production equipment - code API 6A. 
This material falls under the classification of 60K, and often used under temperature rating as L, which is upto minus 46 DEG C.
However you can verify the design requirements for the correct temperature to be used.
