Need help about MP35N
Need help about MP35N
(OP)
Experts,
Want to use MP35N for one component and the component needs to comply with NACE0175 and API 6A, and also satify structural analysis viewpoint. The material Spec I am thinking is:
min YS: 230 ksi
min TS: 240 ksi
min elongation: 15%
min RoA: 20%
min CVN at zero degree C: 20 ft-lb
max HRC: 51
Material will be cold-reduced and then 4 h aging at 704C(1300F). Is this possible? I am personally a bit concerned with elongation. Right now min YS is from my stress analysis, fixed; others are from those NACE and API standards, fixed also. I do have several more heat treatment options after cold-reducing as follow:
----------------------
Aging period, min Temperature
4 732C (1350F)
6 774C (1425F)
4 788C (1450F)
2 802C (1475F)
1 816C (1500F)
Can anyone recommend a heat treatment condition which will satify requirement?
Thanks a bunch

the above min CVN value should be 20 J (15 ft-lb).
