38NiCrMov7-3/38NiCrMov7-7 is a type of low-alloy steel commonly used in the manufacturing of heavy duty machinery and equipment. It is known for its high strength, toughness, and good hardenability.
The main properties of 38NiCrMov7-3/38NiCrMov7-7 material include high tensile strength, good toughness, excellent hardenability, and resistance to wear and corrosion. It also has good impact strength and can withstand high temperatures.
38NiCrMov7-3/38NiCrMov7-7 material is commonly used in the manufacturing of heavy duty machinery and equipment, such as gears, shafts, crankshafts, and connecting rods in the automotive, aerospace, and construction industries. It is also used in the production of tools and dies.
38NiCrMov7-3 and 38NiCrMov7-7 are two different grades of the same material. The main difference between them lies in their carbon content. 38NiCrMov7-3 has a lower carbon content, making it more suitable for applications that require higher toughness and impact resistance. 38NiCrMov7-7, on the other hand, has a higher carbon content, making it more suitable for applications that require higher strength and hardness.
38NiCrMov7-3/38NiCrMov7-7 material is typically hot rolled, followed by quenching and tempering to achieve the desired mechanical properties. It can also be case hardened to increase its surface hardness and wear resistance. For optimal performance, it is important to carefully control the heating and cooling processes during heat treatment.
