GENERAL INFO ABOUT 439
439 stainless steel sheet is a ferritic stainless steel that is titanium stabilized. It shows excellent resistance in fresh water and boiling acids. It is a common choice for automotive exhaust systems, heat exchangers, kitchen equipment, and architectural structures.
Advantages/Disadvantages of 439 Stainless Steel
This stainless steel grade provides excellent protection against fresh water and boiling acids at relatively high temperatures. It can resist both oxidizing environments and stress corrosion cracking. Its titanium stabilizer leads to improved welding capability and it can be work hardened to increase tensile strength. One of the disadvantages of this stainless steel grade is that it is not heat treatable.
PRODUCT FORMS:
Sheet, Strip
SPECIFICATIONS:
ASTM A240
TYPICAL APPLICATIONS:
Type 439 Stainless Steel is attractive for numerous automotive exhaust applications. 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.
