Hot work tool steels enable the hot-forming of work-pieces made of iron and non-ferrous metals as well as alloy derivatives at high temperatures. They are utilized in processes such as pressure die casting, extrusion and drop forging as well as in tube and glass manufacturing. Tools made from hot-work tool steels are not only subject to constantly high temperatures when employed, but also to fluctuating thermic loads occurring where the tool surfaces come into contact with the materials What's the hardness of a hot work steel?What's the hardness of a hot work steel?The normal working hardness is in the range 450 to 600HV. In contrast to the steels in the hot work chromium group, the high tungsten content makes the group unsuitable for water cooling in service.Hot Work Tool Steels : Total Materia Article

Development of The New SteelApplications and Operating ExperienceRecommendationsA new tool steel has been developed, combining the high hardness and temper resistance of high speed steels, along with the toughness of hot work tool steels. The toughness has been maintained by the use of a powder metallurgy (CPM) manufacturing process to eliminate segregation. This steel allows forging and hot forming producers the opportunity to use tooling with significantly higher hardness and longer wear life than offered by traditional hot work steels. The CPM manufacturing process has been used fSee more on gearsolutionsforbest material for gear manufacturingstainless steel spur gearsteel gears for salegear materialsgears for sale metalmaterial to make gearsProduction of a Powder Metallurgical Hot Work Tool Steel Hot Work Tool Steels Total Materia ArticleJan 26, 2017Commercial AISI-H13 gas atomized powders (AT) were mechanically milled (MM) to refine both the particle size and the microstructure.

The tools in these processes are exposed to high mechanical, thermal and tribological stresses which lead to various types of damage [1]. The mechanical and thermal crack formation, plastic deformation and tool surface wear are, in particular, the primary reas of failure in hot forging tools [2]. The tool surface wear is
Nov 01, 2013However, the hardness of H13 hot work tool steel (5153 HRC) is relatively lower than that of H11 steel (56 HRC). SMAT increased the average surface roughness (R a) of H11 steel from 0.22 ± 0.03 m to 1.39 ± 0.02 m. The increase in surface roughness is due to the formation of craters and dimples following the impingement of the SS balls Hot Work Tool Steels Total Materia ArticleSAFETY DATA SHEETSTEEL - ERG, TOOL STEEL 152, Tool Steel 251, 533, Tool Steel 4335, Tool Steel 4340, 31Cr Mo V, Tool Steel A 25, TOOL STEEL A3, AL TOOL STEEL A8, AL TOOL STEEL A8 MOD, Chipper Knife, TOOL STEEL D7, HOT WORK TOOL STEEL H11, IRON, TOOL STEEL L2 MODIFIED, TOOL STEEL W2, TOOL STEEL CRU-WEAR, Vascowear.
