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 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 to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
RINA FH36 ocean engineering steel,Weathering steel for welding structure is added a small amount of alloy elements to the steel, such as steel, chromium, nickel, molybdenum, niobium, titanium, zirconium and vanadium, to form a protective layer on the surface of the metal substrate. Therefore, this improve the corrosion resistance and has good welding performance. Weathering steel for welding structure is mainly used in bridges, buildings and other structures. Our company can supply weathering steel plate, sheet, strip and sections, with various shapes.
Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
RINA FH36 ocean engineering steel,The basic principle of heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
RINA FH36 ocean engineering steel,After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
In February, the North American steel price index was 171.2 points, up 4.6 points on a month on month basis, up 2.8%; the U.S. manufacturing PMI was 50.1%, down 0.8 percentage points on a month on month basis. Among them, the production index decreased by 4.0 percentage points, and the inventory index decreased by 2.3 percentage points; at the end of February, the utilization rate of crude steel production capacity in the United States was 82.5%, 0.2 percentage points higher than that in the previous month. This month, the ex factory prices of major steel products in the Midwest steel works of the United States rebounded. Except for the steel prices remained stable, the prices of other steel products rose.
