differences between a573 grade 70 and a588 grade K steel with coated surface

We have differences between a573 grade 70 and a588 grade K steel, marine steel CCS AH36 hot rolled plates 300tons in Shanghai stock. Specification: 12*1800*8000, 15*2100*8400, 15.5*3150*8200, 12.5*2380*7500, 21.5*2540*5200, 29*2160*6010, 17*1980*5720, 15.5*1700*8400, 18*2300*6750, 18.5*2680*8800, 14.5*1800*6500, 11*1890*6960, 17.5*1500*6790, 13.5*1900*6050, 14.5*1750*8300, 12*1830*9220, 13.5*1900*6050, 14*2000*6000, 13*2470*7780, 13*3020*6700, 12*1610*11240, 19*2090*7070, 14*1820*6500.

The martensite microscopic strength of the wear-resistant layer of the differences between a573 grade 70 and a588 grade K steel, wear-resistant steel plate can exceed HVl700-2000, and the surface strength can exceed HRC58-62. The key to the wear-resistant layer of the wear-resistant steel plate is dominated by cobalt alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are added. The martensite in the alloy composition is filled with fibers, and the orientation of chemical fibers is vertical to the surface.

Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut differences between a573 grade 70 and a588 grade K steel, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
