The base material is 316L secondary smelted, and the body is engraved with a traceable base material code. The key inner surface is visually inspected 100% using a magnifying glass and special lighting fixtures. Surface finish: BA ≤ 0.8um; EP ≤ 0.3um Product description: Pressure resistance coefficient: The working pressure rating is determined by the gasket material at room temperature. Temperature resistance coefficient: For the joint, it is 537°C; for the nickel gasket, it is 315°C, and for the stainless steel gasket, it is 537°C. Cleaning and packaging: Ultrasonic cleaning in a clean room and double-layer packaging in a dust-free room. Vacuum leakage rate: It is determined by the sealing gasket. When using a silver-plated or copper gasket, the leakage rate is 4x10-9 std cm3/s; when using an unplated gasket, the leakage rate is 4x10-11 std cm3/s. 2D and 3D format drawings can be provided.
