With the development of API5L-B pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially the advantages of welded pipe in the range of large-diameter group spacing are more obvious. In 2004, the output of API5L-B (L245) seamless line pipe was about 400,000 tons. The steel grade includes X42-70, ZQS700L automobile structure steel plate, and the varieties include onshore line pipe and subsea line pipe.

EN10083-3 27MnCrB5-2 steel plates usually need quenching and tempering are special application. Up to now, EN10083-3 27MnCrB5-2 steel plates are mainly applied in airplane, guided missile, weapons, railway, bridges, ships, vehicles, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on fields.

Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, ZQS700L automobile structure steel plate.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. ZQS700L automobile structure steel plate, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
