DIN2093 Butterfly Washer

High tensile disc washers with stronger elastic tension, used in strong power load high-speed rail car anti-loosening fastening joint equipment.
Name： High Tension Butterfly Washers DIN6796-HS
Main material: S60C, 65Mn, 60Si2Mn, 50CrVA or SUS304, 316 (A2, A4) and other special customized materials.
Surface treatment: Stainless steel hardened and polished in its original color or spring steel phosphate black, mechanically galvanized, nickel plated, Dacromet coated. (Manufacturing requirements: 42-52HRC)
Common specifications: M2, M8, M10, M12, M14, M16, M18, M20, M22, M24, M27, M30 and so on.    

High-tensile disc washers have stronger elastic tension and are used in strong power-loaded high-speed railcars to prevent loosening and fasten connecting equipment. Disc spring washers belong to the category of safety fasteners, so the professional manufacturing capacity will require a higher, need to do static negative load bearing pressure and dynamic pressure load tests! High-tension washers with a wide range of uses, A bolt with the use of high-tension locking function of the washer, is suitable for high-strength hard connection design, disc washer manufacturing, and application of many conditions affected by the need for scientific understanding and evaluation, otherwise it is difficult to achieve the desired safety features!
Manufacturing implementation standards: in line with DIN6796-HS standards. Specifications: M6-M30 models, can also provide customized service main materials are S60C, 60Si2mn,51crav4, and SUS304\SUS316 special alloys, etc., by isothermal fine hardening after phosphate black, mechanical zinc, zinc-aluminum coating surface treatment! Safety washers are not suitable for chemical surface treatment! Most standard disc spring washers sometimes do not fully meet the design requirements, through the calculation and adjustment of customized to obtain the ideal safety features!
Advantages and features: high axial load, high fatigue life, high load drop (caused by temperature difference) compensation, effective reduction of the negative impact of dynamic load, anti-loosening locking, high elasticity, load concentration uniformity, and high degree of safety.
Application: This product is now widely used in electrical appliances, elevators, towers, mechanical equipment, and medical machinery products supporting disc-type improved fastener products, quality in line with the German standard DIN6796 disc spring standard.
