ASME A588 Gr B HSLA steel plate delivery status: thickness ≤40, hot rolled or normalized; thickness ＞40, normalizedAccording to the different tensile strength of the material, ASME SA204 steel is divided into three strength grades: A, B, and C, namely SA204GrA, SA204GrB, and SA204GrC. The maximum thickness of steel plates corresponding to these three grades is limited to:SA-204A large plate thickness does not exceed 150mmSA-204B large plate thickness does not exceed 150mmSA-204C large plate thickness does not exceed 100mm
"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and A588 Gr B HSLA steel plate product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."
The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they A588 Gr B HSLA steel plate work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.
It is a modern high-tech professional enterprise integrating scientific research, A588 Gr B HSLA steel plate production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A588 Gr B HSLA steel plate process technology development, technology transfer and related technical consulting and technical services.
