GNEE is hot work alloy AISI H13 tool steel china supplier of in round bar, plate, flat bar, sheet, square and block. H-13 tool steel is a type of chromium hot work steel that is commonly used in the manufacturing of tools and dies for high-temperature applications. SAE AISI H13 steel equivalent with JIS SKD61, GB 4Cr5MoSiV1 and DIN 1.2344 Tool Steel and is known for its high hardenability and great toughness. It also combines shock and abrasion resistance, has good red hardness, can resist rapid cooling and withstand premature heat checking.

The H13 tool steel has good machinability, good weldability and good ductility and it can be formed by conventional means. It is commonly used in the manufacture of hot-work dies, extrusion dies, forging dies, and punches. H-13 tool steel can also be used for other applications, such as plastic injection molding, where high-temperature performance and wear resistance are important.

AISI H13 tool steel is characterized by:

High level of toughness and ductility
Good resistance to abrasion at both low and high temperatures
Good high-temperature strength
High through-hardening properties
Very limited distortion during hardening
Good resistance to thermal fatigue

Tempering

Heat the H13 tool steel parts to tempering temperature, soak enough time until to Soak thoroughly. The usual tempering temperature range is 400-650°C(752-1202°F), It depend on the tools hardness require and the operating temperature. H13 tempering data for your reference as below:

Temperature [°C]	400	500	550	600	650
Hardness [HRc]	54	56	54	49	47

Nitriding of H13 tool steel

On some special tool require, the higher hardness is required. Nitriding the H13 steel can get a hard surface case. after Nitriding , the H13 hot work tool steel will have a resistant to wear and erosion surface. Typical Nitriding data for your reference as below:

Temperature	Time	Approx. Depth of Case
525°C	10 hours	0.125mm
525°C	20 hours	0.180mm
525°C	40 hours	0.250mm
525°C	60 hours	0.300mm

Annealing of Tool Steel H13

Heat to 840-860°C(1544-1580°F), Soak thoroughly before furnace cool at a maximum rate of 20°C(68°F) / hour, Cool down to 600°C (1112°F). Then cool in air.
