We are best Manufacturers, Exporters & Stockists of Stainless Steel 321/321H Washers in Italy. Nascent Pipe & Tubes is a well-known firm that exports and manufactures a wide range of SS 321 / 321H Washers, which does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid service. Stainless Steel 321 Washers is used primarily in applications involving continuous and intermittent service temperatures within the carbide precipitation range of 800 – 1500 ° F (427 – 816 ° C).
Washers is applied either in service, or during welding, especially when heating through the range 430 o C – 850 o C, then the carbon and chromium atoms will move (precipitate) coming together to form chromium carbide, depleting the structure of chromium and its corrosion resistance.

Stainless Steel 321 Flat Washers is a heat resistant, titanium stabilized, austenitic alloy that’s commonly used for service in the 1000 ° -1600 ° F temperature range. Stainless Steel 321H Lock Washers has higher hot strength, and is particularly suitable for high temperature structural applications.
Stainless Steel 321 Sealing Washers is a general purpose austenitic stainless steel that is stabilized against carbide precipitation and designed to work within the carbide precipitation temperature range 427 to 816 ° C (800 to 1500 ° F). Stainless Steel 321H Split Washers can be used in most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10 % diluted solutions at elevated temperatures.
