About Our 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. 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 may also be used in many oxidizing environments where Type 304 is considered adequate in terms of general corrosion resistance but is subject to chloride stress corrosion cracking. When application temperatures are too high for Type 409, Type 439 provides good oxidation and corrosion resistance for many automotive exhaust system components and residential furnace primary heat exchangers

Mechanical Properties of 439 stainless steel
| Type | Yield Strength 0.2% offset (KSI) | Tensile Strength (KSI) | % Elongation (2" Gauge length) | Hardness Rockwell |
| 439 Ann | 30 min. | 60 min. | 22 min. | HRB 89 |
Typical Applications of 439 stainless steel
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.
