UNS G41300 material
UNS G41300 material
(OP)
HI Frds,
I am working in valve industry.
UNS G41300 is a alloy steel. i have seen ,many oil and gas company is used UNS G41300 material in valve body.
i cound not found it in ASME Section II , and also ASME B16.34 material table.
Is it because of general service material?
How can find yield strength related to temperature service . or i can take yield strength at room temperature in my calculation?

Title: P-Number for 4130?
Thread: thread292-197673: P-Number for 4130?
Basically ASME does not endorse it.
MatWeb.com lists it closest to 4130 but I am not familiar with the material beyond this.
Good Luck

i'm working on wellhead industry in which i use 4130 (UNS G41300) a lot for wellhead equipment.
In wellhead equipment, valve is also considered as part of it.
anyway, im not sure what you're looking for or even if ASME provide those information somewhere,
but i've seen those standard shows decreasing mechanical properties with respect to increasing service temperature.
both in experiment data and graph.
hope this helps.

Any hard data you find will have a decent variance from lot to lot. One mill run may derate 92% at 300°F, while the next might derate 88%. Generally the data you see in graphs averages that to 90% for 300 °F, and that's generally safe to design with if you use standard safety factors on your allowable stresses.

I've attached a chart from MMPDS-01 for 4130 tensile strength vs temperature.
