ASTM A182 F304 Flange

Stainless Steel 304 /UNS S30400/ 1.4301

Stainless Steel 304L/UNS S30403/1.4303

SS304 is the most common stainless steel.It is an austenitic stainless steel, which has a maximum carbon of 0.08%, while SS304L with carbon maximum 0.03%.
SS304 /304L is used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food-handling equipment.

ASTM A182 F304 flanges come in different sizes, shapes, and designs to suit various applications. The steel flanges are manufactured using advanced technologies to ensure accurate measurements, high-quality finishes, and consistent performance. F304 flanges are suitable for use in high-pressure, high-temperature, and corrosive environments, which are demanding applications. The flange is available in various sizes and types, including weld neck(WN), slip-on(SO), blind, and socket weld(SW), etc.

The ASTM A182 standard defines the minimum requirements for the manufacture and testing of these stainless steel flanges. The standard specifies the dimensions, tolerances, marking requirements, and material requirements for F304 flanges. This ensures that they hold up to rigorous standards of quality and safety, satisfying the requirements of various industries. 
 

UNS S30400 F304 flanges are used in the oil and gas, chemical, petrochemical, and power generation industries, among others. They have found wide applications in piping systems, pressure vessels, heat exchangers, and other industrial processes. They are also used in manufacturing equipment, such as pumps, turbines, compressors, and valves.
