Apr 17, 2021 · 18CrNiMo7-6 is a case hardening steel with high toughness. DIN1.6587 / 18CrNiMo7-6 is a low carbon, case hardening (carburizing) steel which contains 1.8% chromium nickel molybdenum as strengthening agents as per EN 10084. 18CrNiMo7-6 Steel - Hardenability DiagramIf the steel is to be direct hardened, then in general, a carburizing temperature of 950°C is not to be exceeded. After case hardening a typical surface (case) hardness of 62 HRC can be achieved. Gas carburizing for 2 hours at 925°C results in 0.8mm case depth, whilst carburizing for 24 hours at 925°C results in 3.1mm case depth.

8620 Case Hardening Steel Bar EN362 Hillfoot

8620 grade steel is a low alloy case hardening steel. After carburising / carbonitriding and hardening, it produces a hard wear resistant case with a tough core and good resistance to shock. The as quenched surface hardness usually ranges from 37-43HRc. Atlas 6587 Case Hardening Alloy Steel Bar 6587Case Hardening Alloy Steel Bar 6587 The minimum tempering time is 1 hour, but a tempering period of 1 hour per 25mm of section is recommended. If the steel is to be direct hardened, then in general, a carburizing temperature of 950°C is not to be exceeded. After case hardening a typical surface (case) hardness of 62 HRC can be achieved.

Case-Hardening Steel - Ovako

Case hardening entails the treatment of a finished component in a carburizing atmosphere at a high temperature, typically 850950°C, which increases the carbon content at the s Case-hardening steel Carbodur - dew-stahlcase-hardening depth of case-hardening steel at equal carbon curves in the surface layer. According to the diagram, the diffe-rent alloy contents lead to a case-hardening depth that is twice as high in the 17Cr3 steel (CD 0.80 mm) compared with the 17CrNi6-6 steel (CD 1.56 mm) despite the otherwise identical conditions.

Comparison of Very High Cycle Fatigue Properties of

Nov 05, 2020 · This work is aimed to compare the VHCF properties of carburized specimens and pseudo-carburized specimens for the case hardening steel DIN 18CrNiMo7-6, which is commonly used for heavy-duty gears due to its good toughness and high fatigue resistance (Ref 13, 14, 15). Improved Material and Enhanced Fatigue Resistance for Gear Aug 25, 2016 · 4 15FTM02 Fig. 2 Standard range and restricted range of hardenability for the case hardening steel 18CrNiMo7-6 In the following three examples of successful restrictions of hardenability are given. Levers made of 8620H-material were initially supplied using the standard range with a minimum DI=1.7 inches (see Fig. 3).
