Technical service-Zhenjiang Sicheng Bearing Co., Ltd

Selection and pretreatment technology of special stainless steel materials

Material standard: High grade austenitic and martensitic stainless steels such as AISI 316L and 440C are selected.Composition control: The carbon content is strictly controlled at ≤ 0.03%, and 2-3% molybdenum (Mo) element is added to significantly improve the resistance to pitting and crevice corrosion.Incoming inspection: Each batch of raw materials is analyzed for 20 elements using a direct reading spectrometer to ensure full compliance with GB/T 3086 and ISO 683-17 standards, ensuring the purity and consistency of the materials from the source.

Vacuum heat treatment and corrosion-resistant strengthening process

Process conditions: Conduct solid solution treatment at 1050-1080 ℃ under conditions superior to ultra-high vacuum environment.Processing effect: Achieve true "bright quenching", with no oxidation or decarburization on the surface of the workpiece, maintaining the original color of the metal. The hardness uniformity reaches HRC58 ± 1, and the tissue is uniform and dense.
