Machinability is good, similar to law alloy 4032 steel.


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


Weldable 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.


Product is supplied in pipe form and not normally forged from that shape.

Hot Working

Hot working may be done qt 2000 F down to 1600 F if need be. Do not hot work below 1550 F and immediately following hot working cool in a controlled atmosphere furnace from a temperature above 1550 F.

Cold Working

Cold working may be done by conventional methods.


Anneal, or normalize, at 1600 F and air cool.

Strike Temperature Condition

Grade The lowest temperature for strike test
ASTM A333 Gr.6 -150 -100
