Stainless Steel 310H (UNS S31009) is a higher carbon version of 310 Stainless Steel which has a higher carbon content than 310 and is typically used in environments where thermal cycling and resistance to high temperature corrosive conditions is critical.

3003 aluminum alloy is an alloy in the wrought aluminum-manganese family (3000 or 3xxx series).

DIN 17175 12CrMo195 is a specification that covers seamless tubes of heat-resistant steels. The material 12CrMo195 is a low-alloy steel commonly used for high-temperature applications.
