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.
