446 stainless steel pipes are most commonly used in applications with elevated temperatures between 1500 to 2100 °F. These are the only heat resistant stainless steel pipes that can tolerate molten copper,lead,tin,and brass. Likewise,other high chromium ferritic stainless grades, 446 also possess an embrittlement temperature of 885 °F.Hence,it is recommended not to use it in this temperature range of 700-1000° F.Grade 446 is a high chromium,ferritic,heat resistant,stainless steel grade. 446 is known for its excellent resistance to oxidation,corrosion,and sulfidation.
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.
