Otai steel supplies prime 42CrMo4 alloy steel which is widely used as engineering steel.

42CrMo4 Steel Hillfoot

42CrMo4 grade steel is a versatile low alloy steel that possesses good tensile and shock resistance properties combined with ductility. Its resistance to wear can be considerably increased by flame hardening or nitriding (for maximum wear and abrasion resistance). 42CrMo4 SteelThe CCT diagram for the steel 42CrMo4 exhibits ferritic, pearlitic, bainitic and martensitic constituents. The measured upper critical cooling rate is 15 K s-1. Bainite is formed at cooling rates of between 6 K s-1 and 0.3 K s-1.

42CrMo4 steel round 42CrMo4 forging steel 42CrMo4

42CrMo4 can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed. 42CrMoS4 Trafileria MauriBad weldability due to the high crack danger. Hardenability:Medium-good hardenability, suitable for hot purposes till a temperature of 500°. It can be hardened in oil. Notes:CORRESPONDENCE WITH OTHER STANDARDS (purely as an indication):UNI 7845:DIN 17200:ISO 683-1:AFNOR 35-552:AISI-SAE 42CrMo4 42CrMoS4 42CrMoS4 42CD4u:4140:42CrMoS4


The 42CrMo4 high-strength steel employed in the present investigation was provided in the form of bar with the diameter of 20 mm. Cylindrical tensile specimens with 30 mm in gauge length and 5 mm in diameter were machined. Nominal chemical composition (in weight %) of 42CrMo4 Are Quenched and Tempered (Q&T) Steels Readily Also denoted by QT or Q/T, these steels are weldable, but care must be taken to adhere to established procedures at all times, as they often have high carbon contents, and thus high hardenability, leading to a hard heat-affected-zone (HAZ) and susceptibility to cracking. The BS EN 10277-5:2008 (old BS 970 Part 3) steels are good examples of these types of steel.

DIN 1.7225 / AISI 4140 alloy structure steel

1.7225 is a chromium molybdenum alloy steel specification widely used in the oil and gas industry. Similar to grade AISI 4130 but with a slightly higher carbon content. The higher carbon content of AISI 4140 gives greater strength and heat treatment capabilities in comparison to AISI 4130, however it does have inferior weldability characteristics. EN 38MnVS6 Chemical composition, EN 38MnVS6 Our main peoducts of steel are many kinds of special steel, like tool steel, mould steel, alloy steel, alloy constructural steel, heat-resistant steel, high speed tool steel,spring steel and bearing steel , stainless steel and so on, which have formed 12 series and more than 350 varieties with n

EN DIN 34CrNiMo6 1.6582 4337 Engineering Steel - QiLu

EN 34CrNiMo6 Steel is an important alloy engineering steel grade as per BS EN 10083-3:2006. 34CrNim06 steel has high strength, high toughness and good hardenability. EN / DIN 34CrNiMo6 alloy steel has the stability of resistance to overheating, but the white sensitivity of 34CrNiM06 is high. It also has the temper brittleness, so the weldability of 34CrNiMo6 material is poor. Effect of Post Weld Heat Treatment Process on The carbon diffusion from 42CrMo4 to the N80 steel in weld interface may lead to the formation of hard and brittle carbide phases, which is also supported by Lippold & Odegard21. The low toughness can also be attributed to the inclusions at the weld interface22. The small amount of porosity can even be responsible for low toughness.

What is the difference between 42CrMo4 and 25CrMo4 steel

What is the difference between 42CrMo4 and 25CrMo4 steel pipes. What is the difference between 42CrMo4 and 25CrMo4 steel pipes? 25CrMo4 steel pipes are alloy structural steel pipes. When the temperature is 500-520, it has good high-temperature strength, good workability, medium cold bending plasticity, high hardenability, and good welding performance. What is the procedure for welding En19? - TWIWhen 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.
