Q690D material is a Chinese standard high-strength welded structural steel. What does Q690D stand for? Q represents the yield strength, 690 represents the yield strength value, and D represents the quality of the Q690 steel. The quality grades are A, B, C, D, and E, respectively. The impact of Grade D steel plate is﹣20°C. Q690D executive standard: GB / T1591-2008. Q690D steel has high yield strength and tensile strength.
SA516 gr.60 boiler plates are primarily intended for use by pressure vessel fabricators and manufacturers. And, physical and chemical characteristics of the boiler quality plates make these a popular choice in the industries. SA516 gr.60 boiler steel plates are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built. Also, these plates are repellent to corrosion and therefore is long-lasting and can also be used in different environments for a long time without any deterioration.
The chromium plays an important role in Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.
As to the Chemical composition, the different content is a main on carbon content, while the carbon content of A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 grade D is 230MPa (33 ksi).A709 grade HPS50W bridge steel plate
