AISI 4130 Temperature VS Pressure

[Forrest79]

Hi friends,

Can anybody help to find an AISI 4130 material properties, Temperature VS Pressure curve or table. I meet a problem, if I can use AISI 4130 in the condition of API 6A 10000 PSI and 300 degree C temperature. if not, what kind of material I should use. Sorry but I cannot find the support in API 6A.

Forrest;
There is no such pressure vs temperature curve or table for materials. There are allowable stress (this is membrane stress and not fluid pressure) vs service temperature tables for various materials approved for use in specific Codes and Standards. Follow the advice below

API Specification 6A specifies requirements and gives recommendations for the performance, dimensional and functional interchangeability, design, materials, testing, inspection, welding, marking, handling, storing, shipment and purchasing, of wellhead and christmas tree equipment for use in the petroleum and natural gas industries.
