439 Stainless Steel Chemical Composition

Type 439 stainless steel tube withstands temperatures upwards of 1700 f 927 c exceeding the limits of both types 409 and 436.

439 stainless steel chemical composition.

The chemical composition of grade 439 stainless steel is outlined in the following table. Type 439 stainless steel is attractive for numerous automotive exhaust applications. These new grades are sometimes developed for specific end uses and sometimes to improve upon an existing grade. 1 4510 439 sheet and plate.

Typical uses include tubular manifolds and other exhaust system components where temperatures may exceed the oxidation limit of type 409 or where wet corrosion resistance particularly to chlorides is needed. Type 439 is a titanium stabilized 18 percent chromium alloy that may be used in many oxidizing environments where type 304 is considered adequate in terms of general. The alloy resists intergranular corrosion and stress corrosion cracking. Unlike cold rolled stainless steel sheets hot rolled stainless steel sheets and plates cannot be further processed to obtain various finishes.

Aisi type 439 also known as astm xm 8 is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids. Type 439 is stabilized with a titanium addition resulting in good weldability. The composition of ati 439 stainless steel has been balanced to provide a completely ferritic structure at all temperatures to avoid the loss of ductility after welding and to provide resistance to intergranular corrosion.

Chemical composition of astm a240 439 uns s43035 stainless steel plate. Type 439 is an 18 chromium titanium stabilized ferritic stainless steel with corrosion resistance similar to that of 304 304l stainless steel. Its chemical composition gives type 436 ideal formability for difficult to form systems and components. 1 annealed pickled finish.
