Properties of Alloy 20

Alloy 20 Cold Forming

Alloy 20 can be readily hot-formed to practically any shape. The recommended temperature range for hot forming is 1200° to 2250°F (650° to 1230°C).

Alloy 20 Hot Forming

Alloy 20 can be worked by all conventional cold-forming methods. Severe work can be done manually only with the assistance of frequent anneals to restore softness.

Alloy 20 Machining

Alloy 20 can be machined satisfactorily at commercial rates provided proper machining practices are carefully followed.

Alloy 20 Pipe Welding

Alloy 20 can be welded by conventional welding, brazing and soldering processes. Good properties are inherent in these joints. Cleanliness and removal of foreign material are important in attaining sound welds.

Alloy 20 Heat Treatment

Alloy 20 is non hardenable by heat treatment.
