Stainless Steel 304/304L Flanges are flanges made from the stainless steel grades 304 and 304L. These grades are the most widely used austenitic stainless steels due to their excellent combination of corrosion resistance, versatility, and cost-effectiveness. The main difference between 304 and 304L lies in their carbon content, with 304L containing a lower carbon percentage to minimize the risk of carbide precipitation during welding.

The chemical composition of Stainless Steel 304 typically includes around 18-20% chromium and 8-10.5% nickel, along with small amounts of manganese, silicon, and carbon. Stainless Steel 304L has a similar composition but with a lower carbon content, usually around 0.03% or less.

One of the key features of Stainless Steel 304/304L Flanges is their excellent corrosion resistance. They offer good resistance to a wide range of environments, including atmospheric conditions, mild acids, alkaline solutions, and fresh water. However, they may experience pitting and crevice corrosion in chloride-rich environments, so they are not recommended for applications in marine or high-chloride environments without proper protection.

Stainless Steel 304/304L Flanges are easy to fabricate, weld, and form, making them suitable for a wide range of applications across various industries. They have excellent toughness and ductility, making them versatile for various manufacturing processes.

 Stainless Steel 304 Flanges

In terms of heat treatment, Stainless Steel 304/304L Flanges are generally not heat treatable, as they are primarily used in the annealed condition. However, they can be subjected to a solution annealing treatment to reduce or eliminate carbide precipitation at the grain boundaries.

Stainless Steel 304/304L Flanges find numerous applications in industries such as food and beverage processing, chemical and petrochemical industries, pharmaceuticals, and architectural applications. They are commonly used in piping systems, valves, fittings, and other equipment that requires corrosion resistance and hygienic properties. Additionally, these flanges are utilized in kitchen equipment, dairy processing equipment, and transportation components, demonstrating their wide-ranging utility.
