What is the SA514 Gr B steel material continuous casting

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and SA514 Gr B steel 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, SA514 Gr B steel material new materials, and promotes the competition of enterprises Struggle.

Q370R grade is a Chinese steel material for boilers and pressure vessels. "Q" means yield strength, "370" means yield value, and R means container. Delivery status of Q370R steel plate: normalizing -20℃ impact. The steel product SA514 Gr B steel material can also be subjected to controlled rolling treatment or normalizing treatment according to the requirements of the manufacturer or design. The Q370R plates thickness are produced with up to 150mm.

Q345R material is a special steel grade for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and technological performance. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 (16Mn) steel. In addition to the increased tensile strength and elongation requirements compared to Q345 (16Mn) steel, it also requires impact toughness. Q345R steel plate is currently the most widely used and most used steel plate for pressure vessels in China.

The steel such as SA514 Gr B steel material delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
