Production processes of S355JR yield strength

Our company was founded in 2000, which initially committed to providing high-quality steel S355JR yield strength products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export S355JR yield strength steel to the international market, opening up the international steel market.

In the process of S355JR yield strength steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose S355JR yield strength different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.

The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image S355JR yield strength processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the S355JR yield strength steel plate.

LSAW Pipe to Peru. In the beginning of 2014, Peru government released an international tender for one of the hydroelectric power plant. Finally they chose us as the contractor, we purchased the steel plate and then fabricate the S355JR yield strength steel plate into steel pipe, and then make the corrosion protect on the surface, we also supply the fitting with our steel plate, the total value of this order is about 2 million USD.

The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. S355JR yield strength, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.

Safety production is the cornerstone of enterprise survival and development. The company established a safety management network, which achieved clear powers and responsibilities, clear responsibilities, effective management and control, and provided organizational guarantee for safe production. The company strictly complies with the "Environmental Protection Law", establishes an effective environmental protection emission control system and waste gas, waste water, waste solid recycling system, and makes great efforts to harden, lighten, green, and beautify the plant, and strive to build green steel enterprises.
