Product Description
Stainless Steel 316 Introduction
316 is chrome-nickel austenitic alloy. It also contains molybdenum which increases general corrosion resistance,improves
resistance to pitting from chloride ion solutions, and provides increased strength at high temperatures.316 also provide excellent fabricability and formability. It is also called Marine Grade Stainless Steel.

316 Spring Lock Washers Introduction
Spring Lock Washer is a specialized elastic anti-loosening fastener accessory widely matched with bolts and nuts in industrial connection systems. Featuring a split elastic ring structure with unique spring tension performance, the washer generates continuous elastic compression force after assembly, effectively eliminating assembly gaps, preventing thread loosening and offset caused by mechanical vibration, pressure fluctuation and dynamic load. Manufactured from high-quality spring steel, carbon steel and stainless steel materials compliant with DIN, ISO and ASTM standards, spring lock washers possess excellent elasticity, high fatigue resistance and stable mechanical toughness, maintaining lasting anti-loosening effect during long-term repeated vibration working conditions. They are extensively applied in automotive equipment, mechanical manufacturing, electrical appliances,engineering machinery, steel structure facilities, pipeline fastening, railway and aerospace auxiliary assembly, serving as a core essential component to improve connection safety and stability for dynamic fastening scenarios.

316 Spring Lock Washers Product Processing
1.Raw Material Inspection & Blanking:
Adopt high-quality spring steel, carbon steel and stainless steel strip materials that comply with DIN, ISO and ASTM industrial standards. Strictly inspect material hardness, elasticity, tensile strength,surface flatness and internal metallographic structure to exclude cracks, inclusions and oxide defects that may affect elastic performance. Qualified raw steel strips are precisely blanked and cut into standard annular sheet blanks according to washer specifications, ensuring uniform thickness and consistent material properties for subsequent forming processing.
2.Surface Pretreatment & Stamping Forming:
2.Surface Pretreatment & Stamping Forming:
Complete professional surface pretreatment including degreasing, pickling and phosphating to remove surface oil stains and oxide layers, improving surface finish and stamping stability. Adopt precision die stamping technology to finish one-time integral forming of annular outline, inner hole and split opening. The precision stamping process ensures standard dimensional tolerance, smooth incision and regular ring structure, laying a foundation for stable elastic performance of spring lock washers.
3.Trimming, Shaping & Elastic Calibration:
3.Trimming, Shaping & Elastic Calibration:
Remove tiny burrs, flashes and sharp edges on the inner and outer circles and split openings of the washers. Conduct fine shaping and flatness calibration to eliminate deformation and warping caused by stamping.Professional elastic correction is implemented to adjust the opening clearance and ring tension, ensuring each washer maintains stable elastic compression and uniform stress performance after assembly.
4.Heat Treatment & Tempering Stabilization:
4.Heat Treatment & Tempering Stabilization:
Adopt standardized quenching and high-temperature tempering heat treatment process exclusive for spring fasteners. Effectively eliminate stamping residual stress, stabilize material hardness and toughness, and greatly improve elastic fatigue resistance and deformation resistance. This process prevents elastic failure, permanent deformation and loosening failure during long-term vibration and cyclic load working conditions.
5.Surface Treatment & Quality Testing:
5.Surface Treatment & Quality Testing:
Carry out customized surface treatments such as electro-galvanizing, blackening, nickel plating and passivation to enhance anti-rust, anti-corrosion and wear-resistant performance. Conduct full-range professional inspections including dimensional tolerance detection, elastic tension test, hardness detection, fatigue resistance test and surface defect screening to ensure all indicators meet industrial anti-loosening fastening standards and dynamic working condition requirements.
6.Marking, Packaging & Warehousing:
6.Marking, Packaging & Warehousing:
Mark qualified spring lock washers with specification, material grade, execution standard and production batch. Complete automatic sorting and counting, and adopt dust-proof, moisture-proof and anti-extrusion standardized packaging to protect the elastic structure from deformation. All finished products are classified and stored in warehouses and delivered after strict final inspection.
