Low Alloy Tool, Steel Rod, DIN C125W, AISI Approximately W1

Model Number: ZXL049 Brand Name: Baosteel, TISCO Key Specifications/Special Features: Descriptions:Low alloyed water-hardening tool steel, this steel is one of the common water hardening tool steel grades available, W1 is basically simple high carbon steel and is easily hardened by heating and quenching in water, just as with plain carbon steel alloysApplications:W1 is commonly used for hand operated metal cutting tools, cold heading, embossing taps and reamers as well as cutlery for knives, razor blades, cutting tools for machining of steels and metals, broaching tools, tools for screw cutting, chisels, drawing dies, tools for hardest stonesChemical composition (in weight%)C 1.22

Physical properties (averagevalues) at ambient temperature
Modulus of elasticity [10³xN/mm²]: 210
Density [g/cm³]: 7.85
Thermal conductivity [W/m.K]: 45.0
Electric resistivity [Ohms mm²/m]: 0.20
Specific heat capacity [J/g.K]: 0.46
Soft annealing:
Heat to 680 to 720°C, cool slowlyin furnace, this will produce maximum brinell hardness of 213
Stress relieving:
Stress relieving to remove machining stresses should be carried out by heating to approximately 600 to 650°C, holding for 1-2 hoursat heat, followed by air cooling, this operation is performed to reduce distortion during heat treatment
Hardening:
Harden fromtemperature of 760 to 790°C followed bywater quenching, hardness after quenching is about 66 HRC
Forging:
Hot forming temperature: 1000 to 800°C
Machinability:
W1 is plain carbon steel and machines with ease, it is the base line of 100% machinability on which machinability of the other tool steels is compared
Corrosion resistance:
This is plain carbon steel and it will corrode unless protected
Welding:
W1 may be welded by all of the standard techniques
