What is the difference in chemical composition between stainless steel seamless pipes TP316H and TP304H?

Chemical composition of TP304H stainless steel seamless pipe:
Carbon (C): ≤0.045
Manganese (Mn): ≤2.00
Silicon (Si): ≤1.00
Chromium (Cr): 16.00-18.00
Nickel (Ni): 8.00-11.00
Nitrogen (N): ≤0.10‌12
Chemical composition of TP316H stainless steel seamless pipe:
Carbon (C): 0.04-0.10
Manganese (Mn): ≤2.00
Silicon (Si): ≤0.75
Chromium (Cr): 16.00-18.00
Nickel (Ni): 10.00-14.00
Molybdenum (Mo): 2.00-3.00‌23

‌The main difference between TP316H and TP304H is the molybdenum content. ‌
TP316H contains 2.00-3.00% molybdenum, while TP304H does not contain molybdenum.
The addition of molybdenum makes TP316H superior to TP304H in corrosion resistance and high temperature resistance, especially in environments containing chloride ions.

Application areas
TP316H: Due to its excellent corrosion resistance and high temperature strength, it is widely used in petrochemical, marine engineering, chemical, pharmaceutical and other fields, especially in high temperature and chloride environments.
TP304H: Suitable for general industrial and civil fields, such as food processing, chemical equipment, etc., but its application in high temperature and chloride environments is limited.
