National India. Co (India) is one of the largest exporter, manufacturer and supplier of Stainless Steel 446 Round Bars in India. The 446 Stainless Steel Bars is a ferritic, heat resisting, stainless chromium steel. It is a high chromium ferritic heat resistant alloy with excellent resistance to the oxidation, sulfidation and other forms of hot corrosion. Also referred as UNS S44600 Bars, these 446 Stainless Steel bars have exceptionally superior resistance to reducing sulphurous gases, as well as extremely first-rate resistance to oxidation in air.

SS 446 grade is most commonly used between 1500 – 2100°F, although its elevated temperature strength is quite low. SS 446 is the only heat resistant alloy which tolerates molten copper and brass. As with other high chromium ferritic stainless, 446 embrittles severely in the 700-1000°F temperature range (885°F embrittlement). 446 should not be used in this temperature range unless nearly complete loss of room temperature ductility may be tolerated. Sigma phase embrittlement occurs upon long time exposure in the 1000-1300°F range. 

Alloy 446 has a high ductile-to-brittle impact transition temperature. Therefore, successful forming and bending is aided by low forming speeds, edge preparation and preheating to 250-400°F. Annealing, whenever necessary should be performed at 1550-1650°F followed by rapid cool. 

Welding may be accomplished through conventional methods. Pre-heating and post-heating to 300-600°F is helpful. Austenitic weld fillers, such as AWS E310 or E312 are generally suggested to maximize weld deposit ductility.
