Heat Treatment

Alloy 600 is not an age-hardening alloy; cold working is the only available hardening method. Annealing softening begins at approximately 1600°F (871°C) and is essentially completed after heating at 1800°F (982°C) for 10 to 15 minutes. Above this temperature, grain growth may have an adverse effect, but a brief heating to 1900°F will achieve complete softening without causing excessive grain growth. Since the cooling rate has no effect on softening, the material can be water-quenched or air-cooled.

Machining Properties

Hot Working/Forging

Forging should be performed in a low-sulfur reducing atmosphere. Major hot working should be carried out between 2300/1850°F, while light working can continue at temperatures as low as 1600°F. Due to the lower ductility in this temperature range, no hot working should be performed between 1600/1200°F.

Machinability

Alloy 600 can be machined in both hot-worked and annealed states. Due to the significant heat generated during machining, high-speed steel, cast non-ferrous metal, or carbide tools should be used. Tools should be kept sharp.

Turning speeds using high-speed steel and non-ferrous metal tools are 35/45 sfm (0.18/0.23 m/s); turning speeds using carbide tools are 100/175 sfm (0.51/0.89 m/s). (These figures are for initial machine setup only. Values are averages. For some workpieces, the characteristics of the part may require adjustments to speed and feed rate.)

Sulfur-based oil should be used as a lubricant, but it should be completely removed before exposing the machined part to high-temperature environments (e.g., welding).

Cold Working

For enhanced performance, Alloy 600 can be cold-worked at temperatures below 1200°F (649°C).

Welding Alloy 600 can be joined using conventional welding, brazing, and soldering processes.
