The strength of A573 grade 65 CS steel carbon plate, 20 # steel plate is slightly higher than that of 15# steel, rarely quenched, and has no temper brittleness. Cold deformation plasticity is high, generally for bending, calendering, flange and hammer arch processing. Arc welding and contact welding have good welding performance and small thickness during gas welding. Cracks are likely to occur on parts with strict shape requirements or complex shapes.
The company specializes in the research and development, production and sales of A573 grade 65 CS steel carbon plate 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 A573 grade 65 CS steel carbon plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A573 grade 65 CS steel carbon plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for A573 grade 65 CS steel carbon plate pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common A573 grade 65 CS steel carbon plate carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
API 5L X65 steel plate/pipes, under API 5L standard, we can regard X65 steel plate/pipes as large diameter pipes. A573 grade 65 CS steel carbon plate, X65 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X65 steel pipes/plate is a higher strength, tough, weldable steel for applications in the oil and gas industry.X65 Flange Steel meets fully the mechanical property requirements of the API 5LX X65 line pipe specifications whilst maintaining a high degree of toughness and weldability.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
