The seamless steel pipe for general use is rolled by common carbon structural steel, s235j2 carbon steel plate, low alloy structural steel or alloy structural steel, with the largest output. It is mainly used as the pipe or structural part for conveying fluid. According to different uses, it can be divided into three categories: a according to chemical composition and mechanical properties; B according to mechanical properties; C according to hydrostatic test. If the steel pipe supplied according to class AB is used to accept liquid pressure, hydrostatic test shall also be carried out. The seamless pipes for special purposes include seamless pipes for boiler, chemical power, geological and petroleum, etc.

BBNsteel prime quality thick plate s235j2 carbon steel plate product stock: 31*1640*6150, 34*1460*4550, 34*2420*7300, 26*2800*5300, 32.5*3050*7000, 32*1600*4000, 36*1300*4500, 35*1300*4100, 26*2990*6000, 37*1600*8600, 32*2650*5500, 33*2550*6000, 34*2120*6100, 36*1500*6000, 45*1300*4000, 32*3300*6000, 40*1590*8000, 33*1750*6000, 33*1750*6000, 50*1800*6000, 65*2000*6000.

Ningbo port has trade and transportation with more than 50 countries and regions, such as the United States, CIS countries, Europe, Africa, Japan and South Korea, Southeast Asia, the Middle East and Hong Kong. Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.

At the same time can reduce the hardness, improve the s235j2 carbon steel plate plasticity and toughness, improve the cutting performance.Therefore, annealing is not only to eliminate and improve the tissue defects and internal stress left by the previous process, but also to prepare for the subsequent process, so annealing belongs to the s235j2 carbon steel plate heat treatment of semi-finished products, also known as pre-heat treatment.
