3 inch plate A514 Gr P steel material stock

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length A514 Gr P steel material is suitable for the length required by the construction of steel pipes.

In March, the daily output of key iron and steel enterprises decreased on a month on month basis. In terms of enterprise inventory, in late March, the key statistics showed that the A514 Gr P steel material steel inventory of iron and steel enterprises was 18.067 million tons, a decrease of 3.342 million tons or 15.6% compared with the highest inventory in early March, and an increase of 8.534 million tons or 89.5% compared with the beginning of the year.

A514 Gr P steel material, 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.
