The company has allocated special environmental protection facilities for all A514 Gr F alloy steel plate pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, A514 Gr F alloy steel plate steel mill scale, environmental protection dust has reached 100%.
A514 Gr F alloy steel plate, Boiler steel plate is a kind of medium and heavy steel plate used to make important parts of boilers. From the material point of view, boiler steel plate can be divided into special carbon steel plate and low alloy heat resistant steel plate. According to the different working conditions, the boiler steel plate can be divided into two categories: manufacturing room temperature and medium temperature pressure bearing parts steel plate and manufacturing high temperature pressure bearing part steel plate. Boiler steel plate is widely used in petroleum, chemical industry, power station, boiler and other industries.
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with A514 Gr F alloy steel plate, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
Try to use A514 Gr F alloy steel plate high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the A514 Gr F alloy steel plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
A514 Gr F alloy steel plate, Grade P295GH chemical composition under EN10028-2:2003 is displayed as follows. Chemical composition (C: 0.08 to 0.20; Cr: ≤0.30; Si: ≤0.40; Cu: ≤0.30;Mn: 0.90 to 1.50; Mo: ≤0.08;P: ≤0.025; Nb: ≤0.020;S: ≤0.015; Ni: ≤0.30;Al: ≤0.020; Ti: 0.03; N: ≤0.012; Vi: ≤0.02). The yield Strength MPa (min) of P295GH steel plate with thickness less than 16mm is 295MPa, and the tensile strength is 460-580MPa.
