446 Stainless Steel Sheet

SS 446 is a high chromium ferritic grade. The 446 Stainless Steel Plate has an excellent chemical composition giving it enhanced strength. These modules show superb resistance against oxidation and sulfidation. 446 SS Plate is used in temperatures ranging between 1500 to 2100 degrees F however, the strength of these modules at this temperature is low. The 446 Stainless Steel Sheet has a high impact ductile to brittle temperature and can be welded following standard welding procedures. Pre-heating coupled with post-heating of the SS 446 Sheet should be performed at temperatures between 250-400 degrees F.

 

We pride ourselves as Dealer and Distributor of Werkstoff No 1.4762 Perforated Sheet, we supply and maintain ready stock of SS 446 Sheet , see SS 446 Vs SS316

 

SS 446 and SS316 are two versatile components within the stainless grade. Both these modules can be differentiated based on certain features.

•   ASTM A240 Type 446 Plate belongs to a ferritic grade of stainless steel. 316 grade belongs to an austenitic grade of stainless .
•   ASME SA240 446 Stainless Steel Sheet is designed with a chemical composition of 23% chromium and 0.25% nickel. The 316 grade has a chemical content of 16% chromium and 10% nickel coupled with 2-3% molybdenum.
•   SS 316 shows higher resistance against corrosion compared to the SS 446 Shim Sheet. The molybdenum content propels these grades to perform better in stress-induced systems.
•   UNS S44600 Strip has higher strength when compared to a standard 316 stainless grade.

446 stainless modules can be welded following standard welding procedures except for the oxyacetylene welding procedure. The material has to be pre-heated and post heated at temperatures between 300 to 600 degrees F. AWS E310 or E312 austenitic filler material is usually preferred to maximize the ductility of the weld deposit. It is important to maintain a difference between the coefficient of thermal expansion at the base and the weld metal.
