EN steel grade S690QL material property of yield strength
The company's main products are shipbuiling steel plates, boiler plates, container plates, EN steel grade S690QL material pipeline steel plates, structural steel plates, low-alloy plates, steel sections of various materials and sizes. With the advent of the information age, we have also brought new opportunities to Ascendas. The company network will always provide customers with fast online inquiries. We adhere to the principle of honesty and cooperation and organize high-quality and competitive prices. Resources to thank new and old customers for their support, patronage and love for our company!
Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and EN steel grade S690QL material resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, EN steel grade S690QL material new materials, and promotes the competition of enterprises Struggle.
The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by EN steel grade S690QL material metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the EN steel grade S690QL material steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.
With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of EN steel grade S690QL material etc. steel material.
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.
