A514 grade Q steel material coil sheet hardness

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 Q steel material, 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.

A514 grade Q steel material, High-strength steel plates are widely used in many industries such as construction, automobiles, ships, machinery and equipment, but high-strength steel plates must be selected appropriately. First, the grade is too high, which means that the price will be high because of the high manufacturing cost. Second, the low level means that the safety performance cannot meet the standard. Third, we must strictly follow the design drawings to select high-strength steel plates specifications. Fourth, it is advised the purchaser to test the high-strength steel plates with special equipment.

A514 grade Q steel material, Q890E steel plate is a kind of quenched and tempered steel plate for high strength structure, in which "Q" means yield, "890" means yield value, "E" means grade level. Q890E steel is equivalent to EN grade S890QL.Executive standard of Q890E steel plate: GB / T 16270.Q890E steel plate delivery status (heat treatment): quenching and tempering.The size, shape, weight and allowable deviation of Q890E steel plate shall comply with GB / T709.
