Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the A131 grade A boat building steel, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.
In today's A131 grade A boat building steel 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 A131 grade A boat building steel market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched A131 grade A boat building steel increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A131 grade A boat building steel during tempering, while tempering determines the performance and life of the workpiece.
Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with A131 grade A boat building steel, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.
