² Used for making complex shapes of punching dies with material thickness >3mm, such as convex dies, concave dies and inserts. The recommended hardness is 58~62HRC for convex dies and 60~64HRC for concave dies
² Used for making high wear-resistant convex and concave dies in blanking molds. Recommended hardness is guanidine 60~62HRC for convex dies and 62~64HRC for concave dies
² Used for making deep-drawing die which requires high tensile strength, the recommended hardness is 62~64HRC
² sed for making convex and concave molds and inserts of complex shapes in bending molds which require wear resistance. Recommended hardness is 60~64HRC for convex molds and 60~64HRC for concave molds
² Used for making convex and concave dies for cold extrusion of aluminum parts. Suggested hardness is 60~62HRC for making convex die and 62-64HRC for making concave die
