316/316L Pipe & Pipe Fittings Manufacturer
Stainless Steel 316 (1.4401), 316L (1.4404), and 316Ti (1.4571) are highly resistant stainless steel grades widely used in demanding applications across various industries. Known for their added molybdenum content, these grades offer enhanced corrosion resistance, pitting resistance, and strength, particularly in chloride environments. As an improved version of the widely used 304/304L, these grades are ideal for high-temperature and high-stress applications.
Comprehensive Range of 316/316L Pipe Fittings
A full selection of 316/316L pipe fittings is available, including reducers, elbows, tees, crosses, end caps, stub ends, and pipe bends. These products are manufactured according to ASTM A-403, ANSI B16.9/16.28, and MSS SP-43 standards, with compliance to Welding Bevel Standards (ANSI B 16.25) for precise fit and performance. Custom and standard sizes are available to accommodate diverse project requirements, including bending radii from 1D to 10D.
In-stock 316/316L pipe fittings and flanges ensure prompt delivery for a range of needs. Specializing in large-diameter, radiography-tested SS 316 elbows, reducers, tees, and custom fabricated pipes, these fittings offer reliable performance in extreme environments.
Why Choose Stainless Steel 316 and 316L?
Stainless Steel 316 and 316L are the second most commonly used stainless steel grades after 304/304L, offering added benefits with the inclusion of molybdenum for enhanced strength and corrosion resistance. Type 316L, the low-carbon version of 316, offers excellent weldability, while 316H provides increased strength at elevated temperatures. For additional stabilization, Type 316Ti includes titanium, reducing sensitization from chromium carbide precipitation.
