What is the application scope of a516 grade 70 tube

With high-quality a516 grade 70 tube steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our a516 grade 70 tube steel market and improved the control of steel plate production quality.

Continuous rolled steel plates and single rolled steel plates a516 grade 70 tube are often used in many industries. Although the appearance of these two steel plates is very similar and they are same steel grades, in some respects, they belong to two different plates. Because the continuous rolled steel plate is made of strip steel by uncoiling, leveling and shearing, its a516 grade 70 tube comprehensive mechanical properties are not as good as the single rolled steel plate, so some important occasions would choose single rolled steel plate but not continuous rolled steel plate.

DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel a516 grade 70 tube is widely used in punching die, cold work forming die, cold drawing die; forming roll, punch; precision stamping die; precision cutting die for wire cutting and punching die for various purposes; difficult to process materials Tools for plastic deformation; cold forging, deep drawing and thread rolling dies; high-speed punching punches, stainless steel punches.

a516 grade 70 tube, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.

a516 grade 70 tube, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.
