Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and ASTM A283 Gr.D boiler plate heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported ASTM A283 Gr.D boiler plate to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
The thickness of our pressure vessel plates, ASTM A283 Gr.D boiler plate generally ranges 5 to 200mm. According to the working conditions and processing technology of the container, the pressure vessel plate must have good cold bending and welding performance; good plasticity and toughness; high temperature short-term strength or long-term strength performance. In order to make the container can withstand higher pressure and reduce the weight of the structure itself, in addition to high-quality carbon steel, pressure vessel plate is currently made of low-alloy structural steel.
The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, ASTM A283 Gr.D boiler plate, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.
The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the ASTM A283 Gr.D boiler plate, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.
Our company supply various size and thickness ASTM A283 Gr.D boiler plate, hot rolled plates. Plate thickness is available ranging 3mm to 350mm. Steel coils thickness are supplied in max. 25mm. Tolerances for carbon steel coils for conversion to: For minimum gauge orders, thickness and width tolerances are in accordance with the respective ASTM specifications of A568 for thicknesses of less than 0.230 inches(exclusive), and A635 for thicknesses of 0.230 inches to 1.00 inch, inclusive.
Our focus on quality has helped us create an efficiently organised production system, which can supply large-scale piping orders as well as tailor-made orders for smaller clients. We have also created a sales and support network which stretches from Asia to Europe, UAE, South Africa and South America.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
