EN steel grade S690QL material hardness

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 EN steel grade S690QL material 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 EN steel grade S690QL material to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

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.

EN steel grade S690QL material Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.

In 30th,Dec,2018--2th,Jan,2019, One Malaysian customer come to visit our factory to inspect their goods about CCS-AH36 steel plate. This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, EN steel grade S690QL material shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of products.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. EN steel grade S690QL material, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.

The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve EN steel grade S690QL material work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
