Ninthore Overseas is one of the Leading Manufacturer And Exporter of high quality Stainless Steel 317 Washers, which resists attack from phosphoric acid and have been successfully used with nitric acid. SS 317 Flat Washers is unaffected by any of the weak bases such as ammonium hydroxide, even in high concentrations and at high temperatures. Stainless Steel 317 Lock Washers is exposed to stronger bases such as sodium hydroxide at high concentrations and high temperatures that will likely experience some etching and cracking, especially with solutions containing chlorides such as sodium hypochlorite. SS 317 Sealing Washers is a relatively poor conductor of electricity, with significantly lower electrical conductivity than copper.

Other metals in contact with Stainless Steel 317 Split Washers, particularly in a damp or acidic environment, may suffer galvanic corrosion even though the stainless metal may be unaffected. SS 317 Slot Washers is generally highly resistant to attack from acids, but this quality depends on the kind and concentration of the acid, the surrounding temperature, and the type of steel. Stainless Steel 317 Machine Washers is resistant to sulphuric acid at room temperature, even in high concentrations.

Stainless Steel 317 Star Washers are resistant below 10 % and should not be used in the presence of sulphuric acid at any concentration. Hydrochloric acid will damage any kind of stainless steel, such as SS 317 Spring Washers, and should be avoided.
