About Stainless Steel 304/304L/304H Flanges
Stainless steel 304 flanges, or “SS 304 flanges,” are common names for stainless steel flanges. ASTM A182 Grade F304/L and F316/L are commonly used materials standards and grades, with pressure values varying between Class 150 to 2500 and 300 to 600. Austenitic stainless steel with 18% chromium and 8% nickel makes upstainless steel 304/304L/304H flanges. The flanges can also operate well in acidic solutions at mild temperatures, especially without chlorides or fluorides. This grade is prone to crevice corrosion and pitting when exposed to greater chloride levels, even though grade 304 operates well enough in freshwater environments with low rates of chlorides.
Properties of Stainless steel 304/304L/304H flanges :
- This grade of steel has three different flange face types: flat face (FF), raised face (RF), and ring type joint (RTJ).
- These flanges are manufactured in dimensions from 1/2″ to 48″.
- 304 stainless steel industrial flanges must meet the requirements of ASTM A182/A240 and ASME SA182/SA240.
- Because they are made of chromium and nickel, the flanges are strong and corrosion-resistant for typically demanding applications. These Flanges are available in an assortment of dimensions and shapes.
- The substance is potent, having a minimum compressive strength of 515MPa and an elasticity modulus of 205MPa.
- The material is also corrosion-resistant in the majority of atmospheric situations.
- The 304 SS flanges can withstand moderately harsh organic acids such as acetic acid.
- The alloy’s nickel content gives these flanges resistance to mildly reducing solutions, such as pure phosphoric acid at any concentration in both cold and hot solutions, as well as solutions that have been diluted by up to 10%.
Uses of stainless steel 304/304L/304H flanges:
- Due to their tapered hub, these flanges can accept a wide range of inner pipe diameters and are available in several dimensions.
- The stainless steel 304 flanges are simple to weld and offer strong welding links in the fresh water and fuel tanks. These flanges are applicable when temperature variation is a regular occurrence during production.
- The weldability and formability of 304 Grade make it a popular material. These Stainless Steel 304 Flanges provide resistance to a variety of corrosive media and climatic situations. To create plumbing systems, 304 SS Flanges are frequently used to join pipes, valves, pumps, and other machinery.
- These flanges are used in various industrial and residential applications, including mechanical components, food production lines, and automobile headers.
- The grade of flanges is also heat resistant and can endure temperatures of 870 degrees Celsius. This allows the Flanges to be utilised in high-temperature applications like heat exchangers, boilers, and condenser parts.
