Principal Design Features		This is a high strength structural alloy. It is not heat treatable.

Applications		Commonly used in the manufacture of unfired, welded pressure vessels, marine, auto aircraft cryogenics, drilling rigs, tanks, TV towers, transportation equipment, and in missile components.

Machinability		Machinability in the strain hardened tempers (H34, H36, H38) is relatively good. In the annealed (O temper) machining is difficult, but still can be accomplished. Use of lubricants is advised.

Forming		Forming characteristics are best with the alloy in the O temper -- less good in the H36 or H38 tempers.

Welding		This alloy is readily weldable by conventional methods. Use of electric arc welding in particular produces excellent results.

Heat Treatment		The alloy is non-heat treatable.

Forging		No specific data as to hot working range. However the alloy is forgeable.

Hot Working		No data in regard to hot forming. Cold forming characteristics are excellent and usually would not necessitate hot working.

Cold Working		Excellent cold working characteristics in the O temper and somewhat less good in H36 and H38 tempers.

Annealing		Anneal at 650 F for long enough to insure thorough heating. Air cool.

Aging		Not applicable to this alloy.

Tempering		Not applicable.

Hardening		Hardens by cold working only.

Other Physical Props		Electrical conductivity 30% of copper.

Other Mechanical Props		Shear strength for O temper is 23 ksi, for H34 it is 27 ksi
