The KDAMAX is high-performance
hot-tool steel for large-size dies that features superior crack resistance
at the round corners of metal molds and crack resistance at water holes.
1.Superior heat-check resistance.
●Superior heat-check resistance for complicated mold shapes. ●Prolongs
the service life at round corners of metal molds where complex
stresses are centralized when manufacturing thin products. 2.Suppresses large cracks at the water holes. ●Suppresses
large cracks at the water holes due to embrittlement in water
caused by rust. 3.Superior hardening performance. ●Improves the hardening
performance to suppress tenacity deterioration in large-size products.
●Molds with complex shapes with projections and cavities
Cracks in the KDAMAX are as shallow as 40% of those in the SKD61.
2) The width of cracks on the die surface expands slowly.
resistance at R corners
Cracks in the KDAMAX are as short as 40% of those in the SKD61.
2) Cracks from the die surface to the water holes progress slowly.
KDAMAX suppresses rust generation in water in comparison with the
SKD61 and improved steel.
cracks at the water hole of molds improve the service life by 1.3
to 10 times in comparison with the SKD61 and improved steel.
KDAMAX has a 50% higher melting-loss performance than the SKD61.
