Caesarii material selection issue HK40
Thread Content
As the title suggests, I have been doing stress analysis recently, and the material involved is HK40; it should be a material specified by the ASME standards. However, I’m not sure which option to choose from the material database. It seems that TP310 has lower strength compared to HK40. Is there any actual material that can serve as a substitute? I really need help from those experienced on this forum!
1. The grade HK40 is a cast stainless steel of the 25Cr-20Ni type; its ASTM standard designation is SA-351. 2. TP310 is a seamless steel tube. When comparing the two, although their chromium and nickel content is similar, the carbon content in the cast steel is much higher, ranging from 0.35 to 0.45. 3. There is also a significant difference in the yield strength ratio between the two materials: 205/515 for TP310, and 240/425 for HK40. 4. Due to these differences in properties, it may be advisable to use custom input values
