Q390 channel beams
Q390 channel steel beam
Q390, is a low alloy high strength structural steel. Comprehensive mechanical properties, weldability, cold, hot working properties and corrosion resistance are good, C, D, E grade steel has good low temperature toughness.
Steel grade by the yield strength on behalf of the hanyu pinyin letters, yield strength values, quality level symbols of three parts, for example: Q390C. where: Q - steel yield strength of the "yield" word hanyu pinyin first letter; 390 - yield strength Value, unit MPa; C-quality grade for the grade (grade is divided into B, C, D, E).
Suitable for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher loads of welded structural components.
