Additional Information
Welding
All standard welding techniques may be applied to alloy 400. The alloy may also be joined to dissimilar alloys employing appropriate consumables. In addition, joining is possible by brazing or soldering.
Corrosion Resistance
Alloy 400 exhibits resistance to corrosion by many reducing media. It is one of the few alloys that can be used in contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives. Exceptional resistance has been proven in hydrofluoric acid in all concentrations up to the boiling point. Alloy 400 is also resistant to many forms of sulfuric and hydrochloric acids under reducing conditions. Corrosion resistance behavior in seawater is excellent.
Fabrication & Heat Treatment
Typical shaping, forming, machining and joining operations can be used when fabricating alloy 400. Hot working operations should be performed between 1200°F and 2150°F. For heavy reductions a temperature between 1700°F and 2150°F should be used. Cold working should be performed on annealed material. Heat treatments available to alloy 400 are stress equalizing, stress relieving and annealing depending on the mechanical properties desired.
Stress equalizing is performed at a temperature of 575°F for a period of 3 hours followed by a rapid quench. This causes an increase in yield strength with no effects on other properties. Stress relieving is achieved at a temperature between 1000°F and 1050°F for a period of 1 to 2 hours followed by slow cooling. This will reduce stresses without producing a recrystallized grain structure and is recommended to obtain minimum distortion after metal removal.
Annealing will completely soften work hardened material and is performed by holding at temperatures between 1600°F and 1800°F for 2 to 10 minutes followed by rapid quench.
