	Drawn - General Purpose (H58)Temper is used for general purpose tube only, usually where there is no real requirement for high strength or hardness on the one hand or for bending qualities on the other.

	Hard Drawn (H80)Temper is used only where there is need for a tube as hard or as strong as is commercially feasible for the size in question.

	Light Drawn - Bending (H55)Temper is used only where a tube of some stiffness, but yet capable of readily being bent (or otherwise moderately cold worked) is needed.

	Typical Uses: Condensers, condenser plates, distiller tubes, evaporator and heat exchanger tubes, ferrules, salt water piping.

	The values listed above represent reasonable approximations suitable for general engineering use. They should not be used for specification purposed. See applicable A.S.T.M specification references.
