We have an extensive inventory of stainless steel elbows, caps, tees, reducers, crosses, stub ends and many other stainless steel butt welding fittings to meet your specifications and standards. We carry various stainless, carbon, aluminum and nickel alloy butt weld fittings to meet your project needs.
Alloy 446 stainless steel is used to make parts and equipment that require excellent high temperature resistance to oxidation and corrosion. 446 stainless steel pipe and fittings are often found in burners, boiler parts, thermocouple protectors, injector nozzles in molten compounds, flame rods and metal to glass bonding parts.
Alloy 446 stainless steel is a high chromium ferritic stainless steel commonly used in high temperature applications from 1500 °F to 2200 °F. 446 stainless steel is the most oxidation resistant steel among the 400 series stainless'. Its resistance to cyclic oxidation is equal to or better than 309 and 310 steels, but has lower strength at elevated temperatures.
Hastelloy Elbows are fittings that are used to join pieces of piping together. This elbow fitting is available in both a long and short radius and is made from a nickel-based alloy.
The elbow is designed to change the pipe's direction and allow fluid flow through the pipe while maintaining the mainline direction. A Hastelloy elbow ensures that the fluid flows in the direction the system requires.

Hastelloy Elbows Features
The advantages of using Elbows are numerous. First, the alloy's resistance to corrosion makes it an excellent choice for transporting harsh chemicals and materials. Secondly, Hastelloy is known for its durability, meaning that the fittings have a long lifespan when used in the right applications.
The low carbon content of elbows also inhibits the development of carbide precipitation, making them a great option in extreme temperature conditions. They can resist high temperatures, making them ideal for high-pressure and heat applications.
Hastelloy Elbows Applications
Thermowells in corrosive atmosphere
Production of vinyl chloride monomer: resistance to chlorine, hydrogen chloride, oxidation and carbonation corrosion
