Why is water seeping out of the slit when cutting xar 400 steel material
The company specializes in the research and development, production and sales of xar 400 steel material seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has xar 400 steel material five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,xar 400 steel material rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
xar 400 steel material, Structural steel is a kind of steel which meets the strength of specific specifications. Structural steel can be divided into: alloy structural steel, carbon structural steel, low alloy structural steel, heat-resistant structural steel and so on. According to different uses, structural steel can be divided into construction steel and mechanical steel. Construction steel is used to build boilers, ships, bridges, workshops and other buildings. Mechanical steel is used for manufacturing machinery or mechanical parts. Mechanical steel is often used after carburizing or quenching and tempering.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. xar 400 steel material, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and xar 400 steel material pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. xar 400 steel material, 20CrMo steel pipe is generally used in quenching and tempering state.
