Stainless Steel Seamless 446 Grade Pipes

An Stainless Steel Seamless 446 Grade Pipes is a mixture of solid solution composed with two or more elements. There are different types of alloy products such as Aluminum Alloys, Copper Alloys, Nickel Alloys, and Stainless Steel Alloy. Alloy 446 is used to make parts and equipment that require excellent high temperature resistance. These alloy 446 pipes are in form of burners, boiler parts, thermocouple protectors etc.

Alloy 446 Pipes

Alloy 446 pipes are having high heat resistant alloys. This alloy grade is used usually between 1500 to 2500 degrees F. It is having the low temperature content. It has good thermal conductivity. It has high resistance oxidation through 2000 degree Fahrenheit. They are manufactured with standard alloy materials.

Properties

Alloy 446 is a high chromium ferritic stainless steel commonly used in high temperature applications from 1500 degF to 2200 degF. 446 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, but has lower strength at elevated temperatures.

Applications

Alloy 446 is used to make parts and equipment that require excellent high temperature resistance to oxidation and corrosion. Examples include: burners, boiler parts, thermocouple protectors, injector nozzles in molten compounds, flame rods and metal to glass bonding parts.
