HISTAR	DIN	ASTM	C	Si	Mn	P≤	S≤	Cr	Mo	V	W	PROPERTY	APPLICATION
HSH13	1.2344	H13	0.35-0.42	0.80-1.20	0.25-0.50	0.030	0.030	4.80-5.50	1.20-1.50	0.85-1.15	-	High hardenability, excellent wear resistance and hot toughness. has good thermal shock resistance, (ESR) H13 has greater homogeneity and an exceptionally fine structure, resulting in improved machinability, polishability and high temperature tensile strength.	Pressure die casting tools, extrusion die, forging dies, hot shear blades, stamping dies, plastic molds, Hot work mandrels, ESR H13 is great for aluminium die-casting tools and plastic mold tools requiring a very high polish.
HSH12	1.2606	H12	0.32-0.40	0.90-1.20	0.30-0.60	0.030	0.030	5.00-5.60	1.30-1.60	0.15-0.40	1.20-1.40	Excellent impact toughness. The tungsten content provides better temper resistance, deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment. Good resistance to thermal fatigue cracking	hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion dies.
YTR50	1.2343	H11	0.33-0.41	0.80-1.20	0.25-0.50	0.030	0.030	4.80-5.50	1.10-1.50	0.30-0.50	-	High hardenability, excellent toughness, good resistance to thermal shock when water cooled in service, minimal size change during heat treatment.	Recommended for hot tooling applications where maximum resistance to cracking is required. Hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, extrusion dies.
HSH10	1.2365	H10	0.28-0.35	0.10-0.40	0.15-0.45	0.030	0.030	2.70-3.20	2.50-3.00	0.40-70	-	Excellent resistance to softening at elevated temperature. very resistant to thermal fatigue cracking, and can be water cooled in service	Heavy metal Die-casting tools, Piercing Mandrels, Hot punches, forging dies, hot shear blades
HSH21	1.2581	H21	0.25-0.35	0.10-0.40	0.15-0.45	0.030	0.030	2.50-3.20	-	0.30-0.50	8.50-9.50	Exhibits excellent resistance to softening at elevated temperature. Should not be water cooled in service unless the tool includes a continuous flow of internal water cooling. Thermal shock should be avoided	Recommended for difficult hot work tooling applications such as brass extrusion, brass die casting dies, hot punches, forging die inserts.
HSH6	1.2714	L6	0.50-0.60	0.10-0.40	0.60-0.90	0.030	0.030	0.80-1.20	0.35-0.55	0.05-0.15	Ni 1.50-1.80	High impact toughness and good resistance to softening at elevated temperature. good resistance to thermal shock and thermal fatigue cracking, small dimensional changes during hardening.	Die forging, die casting, extrusion, glass processing,. Mandrels, Die holders
