Ubique Alloys Pvt. Ltd is a distinguished manufacturer of ASTM F436 Washers, which is non-hardenable by heat treatment and can only be hardened by cold working. However, the proven ability of ASTM F436 Flat Washers to combat corrosion has widened its use considerably and is now being used for many other industrial applications. Tougher than stainless with a long stringy chip, the use of chip breakers in ASTM F436 Lock Washers is recommended. ASTM F436 Sealing Washers is used in Paper and pulp equipment, Chemical and petrochemical processing, Food processing, etc. ASTM F436 Split Washers should be annealed at 1900 Degree F / 2000 Degree F (1040 Degree C / 1095 Degree C) and water quenched. ASTM F436 Slot Washers is also used in Absorber towers, Boilers, Condenser tubes, Fittings, Heat exchangers, Outlet and inlet ductwork, etc. Work hardening in ASTM F436 Machine Washers is accentuated by the partial transformation of the austenite phase of the material to hard martensitic.
ASTM F436 Star Washers is also used in industries producing paper and pulp, and as condensers in power stations using fossil and nuclear fuels. These ASTM F436 Wire Spring Washers are more resistant to atmospheric and other mild types of corrosion than the stainless steels. ASTM F436 Flat Spring Washers is as well used in engineering and shipbuilding, chemical & Fertilizer production, for onshore & offshore industries, surgical instruments, fasteners, etc.
