from this aspect, an ideal tool should possess the properties of good wear resistance, high mechanical strength and high thermal stability [2].Yong and Tang [3] used a Taguchi method for optimizing the cutting parameters on tool wear in turning of hardened steel with carbide inserts. They observed that 4140 Alloy Steel 1.7225 42CrMo4 42CD4 2244 S 4140 1.7225/42CrMo4 SCM440 42CrMo 42CrMo4 ASTM AISI 4140 alloy Steel Material Mechanical Properties Hardness, Rockwell C:22 HRc, Density:7.85kg/m3 Tensile strength:655 MPa .

EN 1.7225 (42CrMo4) Chromium-Molybdenum Steel

May 30, 2020 · EN 1.7225 (42CrMo4) Chromium-Molybdenum Steel. EN 1.7225 steel is an alloy steel formulated for primary forming into wrought products. 1.7225 is the EN numeric designation for this material. 42CrMo4 is the EN chemical designation. The properties of EN 1.7225 steel include six common variations. This page shows summary ranges across all of them. HCHCR Die and Tool Steel HCHCR Forging HCHCR Flat Pre-heat at 900-950°C then raise temperature to 1050-1100°C. Soak until uniformly heated. D3 tool steel is relatively hard at elevated temperature. Therefore, initial hammer blows must be light and the temperature must not be allowed to fall below 1020°C until the metal begins to flow. Final forging should not be done below 900°C. Influence of the residual stress state of coatings on the Dec 10, 2015 · In Fig. 7 the ratio of the cutting force F c to the thrust force F D for both used materials is exemplary shown for coating 1. The material properties of 42CrMo4 and Ti6Al4V require different process parameters in machining, but with all used coatings the ratio of F c to F D decreases for titanium up to factor two compared to 42CrMo4. Due to this fact the tensile residual stresses of the coating and the additional tensile load in the rake face lead to decreased tool life in machining
