15CrMo steel plate is defined as alloy structural steel plate, and the production standard of 15CrMo steel plate is; WYJ Wuyang Special Technical Conditions.

15CrMo steel plate contains a lot of Cr, and its high temperature resistance, low temperature resistance, and corrosion resistance are also very good, so alloy pipe structural parts, petroleum, chemical, electric power, boilers and other industries are widely used.

The 15CrMo steel plate itself not only has high strength, but also has certain comprehensive high-quality properties such as toughness, fatigue resistance, impact resistance, corrosion resistance, welding and easy processing.

15CrMo is also because it has a variety of high-quality properties. In the process of use, due to the frequent use of the manufacturing industry and the continuous optimization and upgrading of materials by manufacturers, 15CrMo steel plates have also become one of the commonly used steel plate grades in some domestic manufacturing industries. one.
