Production and control of hot-work tool steels Dependent upon their alloy content, hot work steels for forging dies are melted in the open-hearth furnace, by the LD process or in the electric-arc furnace.
Lifetime of hot-work tool steels is often limited by the development of crack nets as a consequence of thermal or mechanical fatigue loading. In this paper, the isothermal and thermal fatigue behaviour of tool steel AISI H11 (German grade X38CrMoV 5-1) in the temperature range between room temperature and 650°C is investigated. In addition to stress controlled isothermal tension-compression Martensitic hot work tool steel die block article and We claim:1. A martensitic hot work tool steel die block article adapted for use in the manufacture of die casting die components and other hot work tooling components, said article having a hardness within the range of 35 to 50 HRC, and a minimum transverse Charpy V-notch impact toughness of 5 foot-pounds when heat treated to a hardness of 44 to 46 HRC and when tested at both 72° F. and at Material selection in hot shaping molds of titanium alloys Jan 01, 2020 · Conclusions ï· Stainless steel have higher corrosion resistance than hot working steel at the operating temperature. ï· 2344, 2714 and 2365 hot work steel show the lowest corrosion resistance. ï· While AISI 304, AISI 310S stainless steels and 2367 hot work steel possess the lowest average surface roughness, 2343-ESR, 2343 hot
By comparing the temper-softening behavior of the high-purity FeC binary martensite, the ratio of the nanohardness H n of the dies steel to that of the FeC binary steel is approximately a factor of two, whereas the same ratio of the macroscopic hardness H v is three at the secondary-hardening peak. These results suggest that the secondary Mechanical characterization of secondary-hardening By comparing the temper-softening behavior of the high-purity FeC binary martensite, the ratio of the nanohardness H n of the dies steel to that of the FeC binary steel is approximately a factor of two, whereas the same ratio of the macroscopic hardness H v is three at the secondary-hardening peak.

1025°F to 1200°F (55°C to 650°C) for unalloyed and low-alloy steels. 1115°F to 1300°F (600°C to 700°C) for hot-work and high-speed tool steels. For many alloy steels, little or no stress relief occurs at temperatures less than approximately 500°F (260°C), while approximately 90% of the stress is relieved by 1000°F (540°C). Time and temperature dependent softening of H11 hot-work Mar 01, 2020 · 1. Introduction. Hot-work tool steels are commonly used for production of dies for high pressure die casting, hot forging and hot extrusion processes, where the steels are exposed to cyclic thermal and mechanical loads .To provide good resistance to wear and damage mechanisms and to avoid failures, dies are adequately heat treated prior to service. Tool Steels for the Plastic Mold Industry - MatmatchTool steels are divided into three groups according to their working temperature - cold work, hot work and high-speed tool steel. Plastic mold steel is a special type of tool steel because it focuses on unique properties required in the application and moreover, steels from all three groups are used in this field.

Wear and Friction Evaluation of Different Tool Steels for The aim of this work is to investigate the durability of tool steels for hot stamping by comparing the wear resistance of three hot work tool steels. Friction and wear behaviours of different tool steels sliding against a 22MnB5 uncoated steel at elevated temperatures were investigated using a high-temperature version of the Optimol SRV reciprocating friction and wear tester at temperatures of Hot Work Tool Steels ::Total Materia ArticleTotal Materia es la base de datos sobre los Metales más comprensiva del mundo:acero, hierro, aleaciones ferrosas, aluminio, cobre, titanio, magnesio, estaño, cinc, plomo, níquel.
