Ground Flat Stock
Precision ground flat stock / gauge plate can be supplied in 100MnCrW4 steel. Available in a wide range of sizes, metric and imperial. Non standard sizes and lengths can be produced in approximately 3 weeks.
Forging
Heat slowly, forging at 980-1000°C. Do not forge below 800°C. After forging cool slowly.
Annealing
As this grade is supplied in the annealed and machineable condition re-annealing will only be necessary if the steel has been forged or hardened. To anneal, heat the steel slowly to 740-760°C, soak well and allow to cool in a furnace to 500°C or below. Annealed hardness will be about 229 Brinell.
Stress Relieving
When the steel has been heavily machined, stress relieving will be beneficial prior to hardening. Heat the component carefully to 670-700°C, soak well and allow to air cool.
Hardening
Ideally pre heat at 300-500°C before raising to the hardening temperature of 780-820°C. Pre heating is desirable for complex sections. Soak thoroughly and allow 30 minutes per 25mm of section before quenching. Light sections should be quenched in oil from the lower end of the hardening temperature range. Tempering is necessary after hardening.
