Surface hardening treatment technology for stainless steel "Expanite"
Increase wear resistance several times. Expanite exceeds the limits of stainless steel.
We would like to introduce our surface hardening treatment technology for stainless steel, 'Expanite'. The low-temperature gas process "Expanite Low-T" achieves a surface hardness of 900 to 1200 HV after treatment, with a hardened layer depth of 5 to 35 μm. The high-temperature gas process "Expanite High-T" results in a surface hardness of 250 to 900 HV after treatment, with a hardened layer depth of 500 to 1000 μm. This technology is suitable for improving the properties of stainless steel, nickel alloys, and titanium materials. 【Features】 ■ Improved surface hardness and wear resistance ■ Enhanced corrosion resistance ■ Increased fatigue strength ■ Improved galling resistance *For more details, please download the PDF or feel free to contact us.
