AISI H11 Hot Work Tool Steel For Hot Working Mold Steel Flat steel block

AISI H11 Hot Work Tool Steel Manufacturer For Hot Working Mold Steel

H11 steel is one of the three most commonly used hot work die steel, the carbide in the steel is small, uniform distribution.Good cold and hot fatigue resistance and corrosion resistance, good hot and cold workability, good hardenability.
In the medium temperature has a thick thermal strength, oxidation resistance, high toughness and wear resistance.

Tool Steel H11 is a chromium-based steel alloy from the “H” family of steels according to the AISI classification system. H11 is one of the most commonly used alloys from this group, thanks to the outstanding impact toughness. Other steels from this group,which have more vanadium, which gives better wear resistance and temper resistance, but worse impact toughness.

Tool and die steel H11 Equivalent and related speciation

Tool and die steel H11 forging

H11 tool steels are forged at 900- 1120°C .Reheat is necessary when temperature below 900°C ,AISI H11 steel should be cooled as slowly as possible in the furnace,annealing is recommended after forged.

Tool and die steel H11 property

Tool Steel H11 is also used for hot tooling applications thanks to its excellent resistance to cracking, including thermal fatigue cracking, gross cracking and thermal shock during water cooling. These include hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion tooling. Like most steels with high toughness and low carbon content, Steel H11 can be used for producing hot-work steels with the water-cooling method.

Tool and die steel H11 applications

AISI H11 is widely usd for highly stressed hot work tools,typical use are:
1.Extrusion Industry: Dies and Contatiner for Extrusion
2.Forging Industry: Forming Dies, Press Dies
3.Die Casting Industry: Dies for Die-Carbide
4.Aircraft Industry: Landing Gears, Arrester Hooks

Commonly used this steel for fixed and moving mold inserts, the steel concentrates high hardness and high toughness, in line with many requirements of hot work mold steel. The main alloy components are chromium, molybdenum and vanadium, which are melted by the process of electroslag remelting.
