Boiler Steel Plate is used for many applications where the pressure inside is significantly higher than atmospheric pressure.More..
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 Q370R heat resisting steel sheets, 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.
In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of Q370R heat resisting steel sheets high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Bebon Iron and Steel's 4300 mm rolling mill, 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's Q370R heat resisting steel sheets technical equipment.
The company has strict control on the quality of Q370R heat resisting steel sheets. Each Q370R heat resisting steel sheets is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the Q370R heat resisting steel sheets meets the specified quality requirements.
The mechanical properties of 18MnMoNbR: the thickness of 18MnMoNbR is 6mm-60mm, the yield strength is not less than 400MPa, the tensile strength is 570-720, and the elongation is not less than 17. The thickness of 18MnMoNbR is 60mm-100mm, the yield strength is not less than 390mpa, the tensile strength is 570-720, and the elongation is not less than 17.Q370R heat resisting steel sheets, 18MnMoNbR is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure vessel, liquefied petroleum gas cylinder and turbine volute.Previous:SPV355 thick plate trade assurance suppl Next:09MnNiDR boiler steel plate price still
