What material is RA330? What material is RA330? Steel
RA330 high-performance high-temperature alloy, carbonization-resistant and oxidation-resistant alloy, carburization-resistant and chloride ion stress corrosion-resistant
RA330 overview:
RA330 alloy is a classic high-performance and high-temperature resistant alloy. By adding 1.25% silicon element, it has good high-temperature strength, and it still has good carbonization and oxidation resistance up to 1200°C. At the same time, RA330 is aimed at Designed to withstand the thermal shock of quenching.
RA330 alloy has very excellent resistance to chloride ion stress corrosion cracking. When selecting engineering materials, if conventional stainless steel suffers from stress corrosion (especially at high temperatures), then RA330 will be a good choice.
The forming and machining of RA330 is similar to austenitic stainless steel and nickel-chromium alloy. Generally, the forming process can be best carried out at room temperature. In most cases, heat treatment is not required after forming and machining. When necessary In this case, it is recommended to completely anneal at 1038-1121°C and quickly air-cool or water-cool.


RA330 welding requires the use of the corresponding RA330-04 welding material. Do not use AWS ER330. Keep the welding interpass temperature low, no preheating is required, and reinforced linear welding beads are used. The machinability index is 20-25% of B1112.
