GH4033 Plate is a Ni-Cr-based precipitation hardening deformed superalloy, with aluminum and titanium added to form a precipitation strengthening phase. It has sufficient high temperature strength when used at a temperature of 700-750 degrees Celsius, good oxidation resistance below 900 degrees Celsius, and good hot and cold processing properties.

1. GH4033 alloy plate has good hot processing performance, with a forging heating temperature of 1140°C and a final forging of 950°C.
2. The average grain size of the GH4033 alloy plate is closely related to the deformation degree and final forging temperature of the forging.
3. The GH4033 alloy plate can be welded by argon arc in the solid solution state. It should be processed in time after welding to eliminate the welding stress.
4. Surface treatment process: The mechanically processed parts need to be electropolished. If mechanical polishing is used, the final polishing and wear marks should be consistent with the length direction of the blade.
5. The heating rate for solution treatment of parts should not be too fast, and a stepped heating curve can be used.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
