Effects of WPC Processing
１：Increased fatigue strength
２：Increased impact resistance
３：Improved sliding performance
４：Increased surface hardness
５：Increased adhesion of films
６：Prevention of low-temperature brittleness
７：Prevention of various forms of corrosion
Examples of Increase in Product Life as a result of WPC Processing
SCM shaft : 5X
SCM gears : More than 8X
SCM torsion bar : More than 8X
SK pump parts : 10X
SUJ needle roller : More than 6X
SUS 304 high-pressure vessel (prevention of stress corrosion cracks) : No occurrence of cracks
