According to the European standard EN10025-3:2004, S275NL weldable fine grain structural steel is mainly used to manufacture the plants of factory, the common construction and construction machinery and equipment. For the bound technical terms,steel plate S275NL have to be done low temperature impacting test in rolling process at -50℃ with minimum energy 27J. Other additional requirements such as UT shall be according to EN 10160, and A588 grade A high strength steel, steel plate S275NL customers can choose the relative classes for Ultrasonic test.
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 A588 grade A high strength steel, boiler steel plate has good welding performance;The A588 grade A high strength steel, boiler steel plate has a good microstructure, white spots and cracks are not allowed.
Vanadium mainly exists in the form of carbide in A588 grade A high strength steel and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
