Stainless Steel 304H Split Washers is constructed using numerous corrosion rate values, generated at different acid concentrations and temperatures. SS 304H Slot Washers represents those Alloys of acid concentration and temperature at which a corrosion rate is expected, based on laboratory tests in reagent grade acids. Stainless Steel 304H Machine Washer exhibits high resistance to chloride – induced pitting and crevice attack, forms of corrosion to which the austenitic stainless steels are particularly prone.
Seawater is probably the most common aqueous salt solution for SS 304H Star Washer. Not only is it encountered in marine transportation and offshore oil rigs, but Stainless Steel 304H Spring Washers is also used as a coolant in coastal facilities.
