Carbide plates

Carbide plates for tooling, stamping dies and wear parts.

Grades and reference properties

Grade	ISO grade	Density (g/cm³)	Hardness (HRA)	TRS (MPa)	Grain size (μm)	Recommended applications
GS40B	K40	14	90.4	3200	0.8	Conventional binder with 15% cobalt with sub micron grain structure for lead frame and connector stamping. Very high strength and excellent wear resistance for low-impact applications. Stamping dies for razor blades, electronic stamping, lead frame dies, lamination, spring steel stamping, crush rolls, coining dies (hard metal). Not recommended for stamping thick stainless steel
GS30B	K30	14.4	91.8	2400	0.8	10% corrosion-resistant binder with sub micron grain structure. Very good wear resistance with high edge sharpness but less shock resistance than higher binder grades. ISO K-30 grade with ideal wear resistance in high-speed stamping. Medium and thin sheets, for coining brass, can die ironing rings, non-gummy steels, compacting dies, stamping dies for razor blades, lead frames(thin copper 0.30‘’), annealed copper, draw dies(300 series stainless steel)
GS35B	K40	14.2	90	3200	2	12% corrosion-resistant binder with coarse grain structure. Very high strength for heavy impact with low wear properties. For standard stamping-impacting punches, coining dies, forming dies, can die punches, swaging dies, cold forming, very severe draw dies for 0.75’’ thick cold-rolled steel,piercing punches (305 stainless steel), gummy steel
