Notes:
①The mechanical properties of the plates (or samples) shall comply with the specifications in the mechanical properties table. When the plate thickness is not less than 7 mm, circular specimens shall be used; when the plate thickness is less than 7 mm, non-standard circular specimens can be prepared. The supplier will only provide actual measured mechanical property data without making a judgment based on these results, but this should be noted in the quality certificate.
②Upon request by the purchaser, the supplier may conduct high-temperature creep performance tests on other alloys. Requirements for high-temperature creep performance and test conditions (such as temperature, stress, rupture time, etc.) shall be determined through negotiation between the supplier and the purchaser and specified in the contract.
Recommended solution treatment : 1140~1180°C, air cooling; Solution treatment: 1200°C±10°C, air cooling
