Hi,
Forged part(s) ~220 lbs. each
Material Grade - 4130
Sour service
Yield needs to be >68,500 with testing done at 400°F
At room temperature we hit ~75,000 yield for this.
According to API 6A Appendix G, for 4130 you need to de-rate the material 88% for a testing temperature 400°F, which would put us under the 68,500 (66,000)
Looking for heat treat recommendations and/or other insights
Thank you in advance!
