| Percentage(%) | ≤ 0.08 | 8.0-10.5 | 18.0-20.0 | ≤ 2.0 | ≤ 1.0 | ≤ 0.045 | ≤ 0.03 | ≤ 0.10 | Bal. |
2.Mechanical Properties
(1).Tensile Strength (T.S): ≥520 MPa
(2).Yield Strength (Y.S): ≥205 MPa
(3).Elongation (E.L): ≥40%
(4).Brinell Hardness (HB): ≤ 187
Manufacturing Process:
The parts are manufactured using the investment casting process. Investment casting is the most commonly used precision casting process for stainless steel materials, maximizing surface finish and ensuring casting accuracy. After casting, the parts undergo precision machining to meet the accuracy requirements of the assembly surfaces. After all casting and machining processes are complete, we perform coordinate measuring machine (CMM) inspection and X-ray internal flaw detection to ensure all dimensions and quality meet specifications.
Packaging and shipment
After all tests are completed and passed, we will package and ship the products. We will maintain order tracking and follow up with customers, providing the most professional after-sales service, and constantly paying attention to customer suggestions and new needs.
