Welding
Weldable by conventional methods.
ASTM A333 Gr.8 steel pipe 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.
Forging
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.
