Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 446 Washers, which is the most widely used of the harden able stainless steels. Heat treated Stainless Steel 446 Flat Washers has mechanical properties comparable to the engineering alloy steel, coupled with the additional benefit of good corrosion resistance. Heat this SS 446 Lock Washer uniformly to 1200 Degree F – 1400 Degree F, remove from furnace and air cool. For maximum softness in SS 446 Sealing Washers, heat to 1500 Degree F – 1650 Degree F, furnace cool slowly to 1100 Degree F, after which air cooling is permissible.

Heat this Stainless Steel 446 Split Washers to 1750 Degree F – 1850 Degree F, soak at heat, and quench in oil, where light sections will also harden by air cooling. SS 446 Slot Washers will harden to some degree when heated 1500 Degree F and over unless slowly cooled to below the critical temperature. Stainless Steel 446 Machine Washer is dried at heat for at least one hour, longer for large sections, and air cool.

Tempering Stainless Steel 446 Star Washers in the range 750 Degree F – 1050 Degree F results in decreased impact toughness and somewhat reduced corrosion resistance. At the solution treating temperature of 1900 Degree F, SS 446 Spring Washer is austenitic but undergoes transformation to a low – carbon martensitic structure during cooling to room temperature.
