Hardening Stainless Steel Knife Blades With Induction
Description
Hardening Stainless Steel Knife Blades With Induction Heating System
Objective Harden a 4″(101.6mm) section of a Stainless Steel surgicalย blade measuring 7″ (177.8mm) long. Hardness should be 48 toย 53 Rockwell C on the blade after processing.
Material 420 Stainless Steel Surgical Blades measuring 7″(177.8mm)ย long, 1/4″(6.35mm) wide at the shank, and 0.085″ (2.2mm)ย thick at the blade.
Temperature 1850ยบF(1010ยบC)
Frequency 365 kHz
Equipment โข DW-UHF-6kW induction heating system equipped with aย remote workhead including one (1) capacitor equalingย 1.2 ฮผF
โข An induction heating coil designed and developedย specifically for this application.
Process A two turn helical coil with an internal quartz tube designed toย scan the length of the blade is used to heat the blade toย 1850ยบF (1010ยบC) to achieve the desired hardness.
Results/Benefits Induction heating provides:
โข Flameless process
โข Improved production rate
โข Consistent & repeatable results
