439 Stainless Steel Sheet
Description type 439 is an 18 chromium titanium stabilized ferritic stainless steel with corrosion resistance similar to that of 304 304l stainless steel.
439 stainless steel sheet. Type 439 stainless steel is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids. 439 stainless steel alloy data sheet 439 oxidation resistance and corrosion resistance is superior to type 409 in areas where temperatures may exceed the oxidation limit of type 409 or where aqueous corrosion resistance particularly to chlorides is needed. 439 is often used in place of type 409 where higher thermal conductivity is required. It may be used in either the annealed cold formed or as welded condition in many applications where other stainless steel alloys such as type 304 type 410 type 409 and type 430are used.
Type 439 is a ferritic stainless steel that is best suited for use in oxidizing environments where excellent corrosion resistance is needed.
