Based on the advantages of A131 grade A boat building steel steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A131 grade A boat building steel products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
The main materials of weathering steel are: Q355GNH, 09CuPCrNiA, 05CuPCrNi, Q345NH, Q235NH, Q295NH, A131 grade A boat building steel, Q275NH, Q355NH weathering steel plate. Weathering steel plate products are widely used in outdoor, indoor decoration, twilight wall decoration and used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing corrosive media in chemical oil equipment.
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with A131 grade A boat building steel, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
The related factors of A131 grade A boat building steel steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different A131 grade A boat building steel steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.
2020 October A131 grade A boat building steel specification: 8*2200*10000, 16*2150*10400, 30*2500*6200, 31.2*2950*9380, 7*2200*8000, 30*2200*10000, 14*2400*9900, 18.5*2700*9570, 21*2100*8810, 14*2070*9060, 12*2200*10000, 14*1950*8000, 36*2200*7700, 7*2200*8000, 14*2070*9060, 10*2200*8000, 20*2500*10000, 14*2400*10000, 30*2000*7400, 6*2800*12000, 21*2100*8810, 32*2200*10000, 16*2150*10250, 27*2500*9000, 20*2100*7000, 21*2100*9100.
