Title:
HOT GASKET WITH STAINLESS STEEL
Document Type and Number:
WIPO Patent Application WO/2015/039005
Kind Code:
A3
Abstract:
A metal gasket for establishing a gas and fluid-tight seal between two members and which is resistant to temperatures of greater than 430°C and even up to 540°C is provided. The metal gasket is made of a 200 series stainless steel which includes, by weight percentage: up to 1.0% Silicon, 3.5-5.5% Manganese, up to 0.060% Phosphorus, up to 0.030% Sulfur, 17.5-19.5% Chromium, 0.50-2.00% Molybdenum, 4.0-6.0% Nickel, 0.10- 1.00% Niobium, 0.08-0.30% Nitrogen and the remainder of Iron. This particular alloy has been found to provide the gasket with very high mechanical strength, even at temperatures of up to 540°C. Additionally, due to the low nickel content of the 200 series stainless steel, the metal gasket may be made more cost-effectively than other known metal gaskets.
