NOGA

• Galling that occurs in high-tensile  molding (adhesive wear due to rising of friction heat) is produced  in a peeling  postion  of surface coating . NOGA combines the characteristics  to resist galling  by improving  adhesion  to surface coating
• NOGA improves service life amazingly further than SKD11 by the   KS-G coating treatment

• NOGA is improved in the toughness and fatigue resistance characteristics  to a large extent as compared with SKD11 steel and SKD11 improved steel

• NOGA enables heat treatment under the same heat treatment conditions of SKD11, and becomes harder than SKD11 by 1 HRC high temperature tempering

• NOGA has a small anisotropy(directional variation) due to dimensional change by heat treatment, and keeps highly accurate die sizes after heat treatment 

NOGA has the secular change characteristics equivalent to SKD11
