For the company's development and take-off, we work together to move forward and create a better Corten B factory tomorrow!

GB/T1591-2018 Q355NB is a low-alloy high-strength structural steel. This steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Steel Corten B factory products are delivered in hot rolled, normalized, normalized rolled or thermomechanical rolled (TMCP) state.

Compared with carbon steel, alloy steel has higher strength, better heat resistance, better low temperature resistance, better corrosion resistance and other advantages. Some of its work environment can not be adapted by carbon steel. Therefore, alloy steel is a common and important material in pressure pipeline. Low alloy steel, Corten B factory quenched and tempered steel, stainless steel, heat-resistant steel and low temperature steel are commonly used in pressure pipes.

Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as Corten B factory, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.

Chemical composition of Q420 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 Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. Corten B factory, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
