There are many types of EN 10083-3 30CrNiMo8 alloy steel etc. alloy steel plates, which can be divided into different types according to different standards. If divided according to the element composition of the alloy, the alloy steel plates can be divided into four types. The first is chromium steel, in which chromium is an important part of alloying elements. The second type is chromium-nickel steel, the third is manganese steel, and the last type is silico-manganese steel. The types of these alloy steel plates are named according to the composition of the alloying elements contained in the steel, so you can roughly understand their composition based on their names.
The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The EN 10083-3 30CrNiMo8 alloy steel, boiler steel plate has good welding performance;The EN 10083-3 30CrNiMo8 alloy steel, boiler steel plate has a good microstructure, white spots and cracks are not allowed.
The allowable temperature of EN 10083-3 30CrNiMo8 alloy steel, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of EN 10083-3 30CrNiMo8 alloy steel work, the actual stress of EN 10083-3 30CrNiMo8 alloy steel under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of EN 10083-3 30CrNiMo8 alloy steel under the temperature.
