heat treatment process of 42crmo alloy steel plate
Alloy structural steel is provided with higher yield strength, tensile strength, endurance strength, yield ratio (about 0.85 generally ) enough plasticity and toughness. The concentration of alloy element of this kind of steel is quite high, mainly are corrosion resistant steel, heat resistant steel, wear resistant steel, and other special steels of physical and chemical properties. 42CrMo4 steel and 42CrMo steel difference WixSteel42CrMo4 is from European standard-EN10083, 42CrMo4 is a kind of alloy steel with high hardenability, good toughness and small deformation during quenching.42CrMo is China GB/T standard grade, it is a medium carbon alloy structural steel with good mechanical properties, good
ity, refer to our Plate Steel Specification Guide. Two pressure vessel plate steel specifications comprise, by far, the most popular process vessel applications. Based on ArcelorMittals experience, ASME SA516 (ASTM A516) carbon steel and ASME SA387 (ASTM A387) alloy steel are detailed technically in this bro-chure. Production Practices AISI 4130 Steel - 25CrMo4 - JIS SCM430 - GB 30CrMo If the temperature is 300-350 on the heat treatment processing, get the flake is a tendency. It is medium-Carbon alloy steel which can be oil quenched to attain a maximum as-quenched hardness of approximately 48HRC. Its hardenability is significantly higher than that of the carbon-molybdenum(40xx) grades. 4130 Alloy Steel Applications AISI 4140 Alloy Steel 42CrMo4 Alloy Steel - Special Steel Heat Treatment. AISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating at 913°C (1675°F) for a long period of time followed by air cooling. Forging. Forging of this steel should be carried out between 2200 and 1650 º

Fundamentals of the Heat Treating of SteelChapter 2:Fundamentals of the Heat Treating of Steel / 11 Steel, however, is by far the most widely used alloy and for averygood reason. Among layman, the reason for steels dominance is usually con-sidered to be the abundance of iron ore (iron is the principal ingredient in all steels) and/or the ease by which it can be rened from ore
The cooling process is the key process in heat treatment, it determines mechanical properties of steel pipe after cooling process. Four main heat treatment methods in carbon and alloy steel pipe industry. The heat treatment processes for steel pipe includes normalizing, annealing, tempering, quenching and other process. Normalizing SCM440 Alloy Steel Supply from Taiwan - JFS Steel steel Conditions of heat treatment.

Tensile strength (kgf/mm²):100 Yield strength (kgf/mm²):85 What is heat treatment of steel Heat treatment processThere are three types of steel heat treatment. Such as overall heat treatment, surface heat treatment, and chemical heat treatment. According to the mediator, temperature and the way of cooling of heat treatment, every classification can be divided into several different heat treatment process.
Process specification of 42CrMo steel plate:Hot working specification of 42CrMo steel plate:The heating temperature is 1150 ~1200 degrees C, the starting temperature is 1130 ~1180 degree C, the termination temperature is 850 degrees C, and the retarding cooling is achieved when Phi > 50mm.
