The Charpy impact energy at -12°C of the air ,oil and water quenched samples after 560°C tempering is 12J, 22J and 59J, respectively. The decrease of proeutectoid ferrite
What is 42CrMo steel material used for? Compare with the 35CrMo, 42CrMo is a better option. Due to its great properties, people usually use 42CrMo steel round bar or plate to make the important fittings those with higher strength and bigger cross-section size than 35CrMo. 42CrMo vs 4140 vs 42CrMo4 (EN 1.7225) SteelChinese GB Standard The following tables show 42CrMo vs 4140 vs 42CrMo4 (1.7225) steel, they are similar in chemical composition and mechanical properties and are all belong to alloy steels. Tags:42crmo vs 4140, 42crmo vs 42CrMo4, EN 1.7225 Steel
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 steel round 42CrMo4 forging steel 42CrMo4 Jul 10, 2020 · 42CrMo4 steel can be hot worked at 816 to 1038°C. 42CrMo4 alloy steel can be cold worked using conventional methods in the annealed condition. 42CrMo4 steel is annealed at 872°C followed by slowly cooling in the furnace. 42CrMo4 alloy steel can be tempered at 205 to 649°C depending upon the desired hardness level.
