Strict requirements for boiler steel plate materials

Strict requirements for boiler steel plate materials

Posted:2021-11-08 11:08:43

Because boiler steel plates are products for important purposes, the safety and reliability requirements are strict, and the manufacturing technology is difficult, so the materials must have the following main characteristics:

Boiler steel plate materials have high yield strength performance in a certain temperature range (medium normal temperature and high temperature);

Boiler steel plate material has sufficient toughness, no brittle failure accident will occur during manufacture or use;

The boiler steel plate material has a small strain aging sensitivity, especially in the corresponding working temperature area, a certain value of aging impact energy must be guaranteed;

Boiler steel plate material has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;

The boiler steel plate material has good welding performance;

The boiler steel plate material has a good microstructure, and no white spots and cracks are allowed.
