Monel 400 Washers Manufacture


Sachiya Steel International is one of the prominent stockiest and supplier of quality Monel 400 Washers has excellent mechanical properties at sub – zero temperatures. However, excellent results can be obtained in these Monel 400 Flat Washers if you make the correct choices for tooling and machining.

Monel 400 Lock Washers is a solid – solution binary alloy, which can be readily joined and fabricated. As nickel and copper are mutually soluble in all proportions, these Monel 400 Sealing Washers is a single – phase alloy. Monel 400 Split Washers will exhibit only randomly dispersed non – metallic inclusions, where these consist of metal sulphide or silicates.

By proper control of the amount of hot or cold work and by the selection of appropriate thermal treatments, finished fabrications in these Monel 400 Slot Washers can be produced to a rather wide range of mechanical properties. Monel 400 Machine Washer has a melting range of 1300 Degree C – 1350 Degree C and an electrical conductivity.

These Monel 400 Star Washers is used in the section of Alkylation units in direct contact with concentrated hydrofluoric acid. Monel 400 Wire Spring Washers offers exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point. These Monel 400 Flat Spring Washer is perhaps the most resistant of all commonly used engineering alloys, where strength and hardness increases with only slight impairment of ductility or impact resistance.
