Hull structural steel is divided into general thickness and high-strength steel. General strength steel is divided into four grades of A, B, C and D; high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36, EH36. In order to ensure quality and ensure sufficient toughness of hull structural steel, the chemical composition of Mn / C is required to be above 2.5, and the carbon equivalent is also strictly required. Our Hull structural steel plates can be supplied with certificates from different classification societies.
A709 grade 100W bridge steel plate,The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.
Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
The spot price of 300 series stainless steel market has been slightly lower, and the previous increase has been further digested. But after the price of 304 hot-rolled plate and 304 cold coil rose, the market bullish mood seems to be stirred again. However, the spot price did not increase with the period, but mainly based on stable shipment. In particular, the current price of 304 hot-rolled large plate futures is close to the spot price; in addition, the recent poor market transaction price increases slightly resistance.A709 grade 100W bridge steel plate
