42CrMo4 - Ovako

42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening. 42CrMo4 / 1.7225 - SteelNumber - Chemical composition Chemical composition of steel 42CrMo4 (1.7225), Standards of steel 42CrMo4 (1.7225) Mechanical Properties of steel 42CrMo4 (1.7225) Equivalent grades of steel 42CrMo4 (1.7225) steel 42CrMo4 (1.7225) Tensile Strength, Elongation, Proof strength , Hardness

Analysis of Tempering Treatment on Material Properties of

Apr 14, 2007 · DIN 41Cr4 and DIN 42CrMo4 materials have been widely used in automotive driving elements. Although 42CrMo4 is more expensive than 41Cr4, it is more preferable in terms of material properties. In this study, these two materials were heat treated by austenitizing in a continuous furnace at 850 °C and quenched in oil at 90 °C. After they were tempered at various temperatures, mechanical Datasheet for Steel Grades Specialsteel 42CrMo442CrMo4 Mechanical Properties Tensile strength 231-231 b/MPa Yield Strength 154 0.2 /MPa Elongation 56 5(%) - (%) Akv - Akv/J HBS 235-268 - HRC 30 - 42CrMo4 Heat Treatment Regime Annealing Quenching Tempering Normalizing Q & T 42CrMo4 Range of products

Hydrogen diffusion and trapping in A 42CrMo4 quenched

Nov 06, 2020 · A 42CrMo4 steel quenched and tempered at different temperatures was tested via a combination of electrochemical hydrogen transient build-up Induction Tempering vs Conventional Tempering of a Heat An induction heat treatment is favorable compared to a conventional one mainly due to significant time and cost savings. Therefore, in this study, the microstructure property relationships during induction and conventional heat treatment of a heat treatable steel 42CrMo4 is investigated. The yield strength and hardness is slightly higher for the conventionally heat-treated steel, whereas the

Martempering/Marquenching - Hardening and tempering

Interrupted quenching of steels typically in a molten salt bath, at a temperature just above the martensitic phase. The purpose is to delay the cooling for a length of time to equalise the temperature throughout the piece. This will minimise distortion, cracking and residual stress.

What is the procedure for welding En19? - TWI

When welding is completed allow components to cool to 200°C before tempering; Heat to 620 - 650°C at a maximum heating rate of 100°C/hr or 6000/thickness (mm) °C/hr, whichever is the smaller. Temper for 2 hours. Cool to 200°C at controlled cooling rate of 100°C/hr maximum. Cool to Steel 42CrMo4:characteristics, properties, analogues Steel grade 42CrMo4 is an alloy steel for quenching and tempering. Grade 42CrMo4 products are mainly used for the manufacture of machine parts. Steel is made in accordance with the requirements of the DIN EN ISO 683-2 standard (formerly EN 10083-3).
