Chemical Requirement Composition(%)

A For each reduction of 0.01% carbon below 0.30%, an increase of 0.05% manganese above 1.06% would be permitted to a maximum of 1.35% manganese.

TENSILE REQUIREMENTS

Impact Temperature

Minimum Impact Test Temperature -45 C(-50 F)

Impact Requirements

Straight line interpolation for intermediate values is permitted.

Machinability

Machinability is good, similar to law alloy 4032 steel.

Forming

The product comes in piping form but may be formed readily by conventional methods.

Heat Treatment

Product is supplied in the normalized, 1500 f and air cooled, condition. It may be quenched and tempered by heating to 1475 F, quench in circulating water and then temper by re-heating to 1100 F and rapid air cooling.
