Applications of H11 steel material

H11 steel is a typical alloy Tool steel, Its Hot work Mechanical Properties is very nice. It is that the US air-hardening hot work die steel, the steel-casting industry is one of Europe’s three most common hot die steel, steel carbide small, uniform distribution, resistance to thermal fatigue resistance and corrosion properties good, good hot and cold workability, hardenability well in temperature has a thicker heat forced, oxidation resistance, high toughness and wear resistance


Forging of H11 steel material

Preheat slowly to 750°C then increase the temperature more rapidly to 1050-1100 °C. Do not forge below 850°C. Then cool the H11 slowly in furnace after forging.


Annealing of H11 steel material

AISI H11 tool steel is delivered condition normal at annealing and machineable. If need re-annealing. Heat the H11 steel and Soak thoroughly to 820~860°C, then cool in furnace. After annealing, the H11 delivery hardness is 255HB Max.


Stress Relieving of H11 steel material

When must tools made from H11 alloy tool steel are heavily machined or ground , the relief of internal strains is advisable before hardening to minimise the possibility of distortion. Stress relieving is very necessary, stress relieving should be done after rough machining.


Hardening of H11 steel material

 

AISI H11 Delivery condition usually is Annealing, so hardening is necessary. Heat the H11 tools in a controlled atmosphere furnace, if have not the controlled furnace, pack hardening is recommended strongly.  Pre-heat H11 tool steel to 780~820°C, soak enough time until heat through. Then brought up to 1000-1030 °C, Quenching in oil quenching.


Tempering of H11 steel material

Heat the AISI H11 to 400-650°C, Heat uniformly to the required temperature allowing a soaking time of two hours per 25mm of ruling section. Withdraw from the furnace and allow to cool in air.  Different tempering temperature will get different hardness. Commonly used / ℃ tempering temperature: 100 ~ 400. Typical Tempering temperature is 552℃, after tempering get 53 HRc Min.


Welding  of H11 steel material

In general, we do not advise the welding of alloy tool steel but users sometimes prefer to weld in order to avoid the cost of retooling. It should be remembered that this grade is an air hardening steel and that in welding the area of the weld attains a temperature of about 1000°C. Cracking is likely to occur during cooling unless proper precautions are taken. Popular methods of welding are atomic hydrogen and argon arc. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding alloy tool steels.


Nitriding of H11 steel material

H11 alloy tool steel can be nitrided to give a hard surface case. After the nitriding heat treatment, the H11 is then very resistant to wear and erosion. Nitriding also increases resistance to corrosion.


Final Grinding of H11 steel material

Grinding the AISI H11 Steel. Select the correct grade of wheel in consultation with the grinding wheel manufacturer. Ensure the grinding wheel is in good condition by means of a suitable dressing tool. Wet grinding is a preferable option using a copious supply of coolant. If dry grinding is resorted to then use a very soft wheel.
