I have a database with NA equivalents to Euro grades, the following I cannot find, anyone have equivalents?:
10CrMOVNb9
22CrMoV12
21CrMoNiV4
I appreciate any assistance on this, thank you
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...
We changed ingot size from ~46" Round to ~26" square for forging of the subject line material. Forged the ingots down to H-20”, W-28”, L-21 ft, we made the switch to save time in forging (Open Die). This was the only major change in process
After cooling to 90° we placed in furnace, ramped to...
27 NiCrMoV 15-6
Y-760 Mpa
T-900 Mpa
Trying to find a NA equivalent, our history he closest I can find would be a 4330V MOD for the high Ni
Anyone worked with this before and offered or determined an equivalent I can actually offer & get from supplier?
Hello,
Forgings
Part weight – ~200 lbs
Material - 4330V per AMS 6427
Tensile – 130,000 min
Yield – 109,000 min
Impacts – 55 ft/lbs min @ RT
Hardness – ?
Looking for heat treat advice to meet mechanicals. Impacts and what hardness is what I have no history on.
Thinking quench & temper should...
Customer has specified that they want material 316ss for a forging and material must indicate NACE MR0175 and EN 10204 3.1b - Dimension ~27" Diam. x 7" thick
Both of these are new for us.
I have determined that there is no “NACE Test” that can be used to certify that a material meets MR0175...
We are forging. Customer requested a change from 2219-T62 to 2219-T6.
What's the difference, if any. What should I look out for in process?
Any heat treat information they look to be identical, I am not very experienced with Aluminum.
Thank you
Greetings,
We are using a 4330 modified;
C - 0.32
Mn - .60
Si - .26
Ni - 3.40
Cr - 1.20
Mo - .48
V - .118
We need transverse -40f impacts @ 34J average no lower than 27J
We cannot meet these requirements after many different heat treatments.
Does any one have experience with this grade mod...
