Phosphorus is a very harmful element in A514 grade H alloy steel plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of A514 grade H alloy steel plate steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the A514 grade H alloy steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A514 grade H alloy steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. A514 grade H alloy steel plate, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
