Stainless Steel 904L Pipe Fittings Overview
Aesteiron is a trusted and experienced manufacturer of 904L stainless steel pipe fittings in India, producing fittings that meet both national and international standards. These fittings are available in various sizes, thicknesses, and dimensions to suit a wide range of applications. Common types of 904L stainless steel fittings include elbows, tees, reducers, couplings, unions, caps, adapters, valves, plugs, and more.
ASTM A403 WP 904L is a low-carbon, non-stabilized austenitic stainless steel designed to provide excellent resistance to corrosion, particularly in environments containing strong reducing acids like sulfuric acid. This is achieved by adding copper to the alloy. 904L is also non-magnetic and exhibits excellent formability, weldability, and toughness. The high nickel and molybdenum content make it resistant to stress corrosion cracking, particularly in chloride-rich environments, such as warm seawater.
ASTM B366 UNS N08904 pipe fittings are commonly used in highly corrosive environments, with copper additions providing resistance to sulfuric acid under both mild and aggressive conditions. 904L stainless steel elbows are used to change the direction of flow in a piping system, with 90° and 45° elbows being the most popular. The 90° elbow is commonly used to connect hoses to water valves, pumps, and deck drains, while the 45° elbow is ideal for water supply systems, food processing pipelines, air conditioning lines, and agricultural facilities.
