S460QL steel plate for boilers and pressure vessels

16Mo3 steel is a kind of European boiler steel plate. 16Mo3 is different from other raw materials when welding. It must be preheated first, and the weld should be kept for about 30 minutes after the welding is completed. S460QL steel plate, 16Mo3 manganese steel is also an important alloy element steel, it is an important hardenability element. 16Mo3 alloy is a material used at elevated operating temperatures, such as weldable steel in the manufacture of industrial boilers and stainless steel pressure vessels in the petroleum, natural gas and chemical industries.

In today's S460QL steel plate steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of S460QL steel plate market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Laser cutting S460QL steel plate has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the S460QL steel plate cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for S460QL steel plate and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

Both parties shall confirm the S460QL steel plate material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the S460QL steel plate steel plant.
