Workability
Forging: Forging of the W1 tool steel can be performed at 1038°C (1900°F) down to 816°C (1550°F) but not below 843°C (1500°F).
Machinability: The machinability of W1 tool steel is very good as they are plain carbon steels with 100% rating based on which other tool steels are compared.
Forming: W1 tool steel can be easily formed using conventional methods.
Welding: W1 tool steel are weldable using all the standard methods.
Hot Working: W1 tool steel can be hot-worked.
Cold Working: W1 tool steel in the annealed condition have very good ductility and can be easily cold worked using conventional methods.
Heat Treatment:
The treatment depends upon the intricacy of the part or section size. W1 tool steel with large sections or intricate shapes have to be slowly preheated to 593°C (1100°F) and then the temperature should be slowly increased to 816°C (1500°F). The steels should be maintained at the same temperature for 10 to 30 minutes and finally water or brine quenched.
ANNEALING:Annealing has to be performed at 760°C (1400°F) followed by slow furnace cooling at 4°C (40°F) per hour or less.
STRESS RELIEVING: Heat slowly to 1200 to 1250° F. Soak for two hours per
inch of thickness at heat. Soak, slow cool (furnace cool if possible) to room temperature.
HARDENING:
Preheat: Heat slowly to 1200 to 1250° F. Soak for two hours per inch of thickness at heat. Soak, slow cool (furnace cool if possible) to room temperature.
Harden: Heat to 1425 to 1475° F. Soak at heat for 30 minutes per inch of thickness.
Temperatures on the high side of the range will increase the depth of the case.
Quench: This material may be water quenched, but brine quenching is preferred. Water or
brine quench to 150 to 200° F. Oil quenching is sometimes used for light sections and where maximum hardness is not required.
Temper: This material may be water quenched, but brine quenching is preferred. Water or
brine quench to 150 to 200° F. Oil quenching is sometimes used for light
sections and where maximum hardness is not required.
Introduction:
Water-hardening tool steels are also known as group W steels. This group consists of three types, namely, W1 tool steel, W2 tool steel, and W3 tool steel. The main alloying element found in group W steels is carbon. To increase the wear resistance and hardenability of the W steels, a small amount of chromium can be added. By adding vanadium, the grain size is maintained, which enhances the toughness of the steels. The group W steels have low resistance to softening at high temperatures and are inexpensive.
The W1 tool steel is one of the most commonly available water hardening tool steel grades and can be easily hardened by heating and quenching in water. However, this alloy does undergo some amount of distortion during quenching.
Applications:
The W1 tool steel is mainly used for cold heading, hand-operated metal cutting tools, reamers and embossing taps. It is also used for cutlery.
