Stainless steel 904L flanges are the most demanded in all types of industries. These flanges are made with premium quality raw materials and technology. These flanges are used in various sectors for multiple purposes. Stainless steel 904L flanges are commonly made of chromium-nickel austenitic steel. This combination consists of 19% of chromium and 23% of nickel content in major quantities. The combination also includes manganese 2%, carbon, silicon, phosphorus, sulfur, copper and 5% molybdenum. This grade is also known as UNS N08904. .
Stainless steel 904L grade have low carbon properties and high thermal conductivity. These flanges offer great corrosive resistance features. It provides resistance from oxidation, reduction and erosion. It also has high tensile and yield strength. These flanges are commonly used as big machinery equipment, condensers, boilers, etc. These flanges also provide great protection from sulfuric and chloride environments. The minimum tensile strength of these flanges is 490Mpa, whereas the yield strength is 220 Mpa. These flanges are weldable, and they have great forming features. The flanges also have a high melting point (1350°C estimated).
