S355J2WP equivalent table,A572 Gr 70 , which one is better for construction?

Our S355J2WP equivalent table, CCS AH32 shipbuilding steel plates stock and specification (mm): 14.5*2450*5410, 14.5*4180*7500, 25.5*4210*6870, 14.5*2950*6570, 15.5*2200*7080, 15*2200*6720, 13*2190*8000, 21.5*1500*5480, 20.5*1500*6530, 11*2060*7550, 25.5*4230*7020, 16.5*2020*6180, 23*4210*5620, 23*4160*7310, 15*2430*11560, 15*2180*6720, 18.5*2450*7990, 11*3070*9200, 18.5*2800*7180, 23*3800*7100, 13*2610*8190, 13*1600*6900, 28*2330*5420, 17.5*2440*6220, 12.5*1630*5000, 13*1600*7390.

In today's S355J2WP equivalent table 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 S355J2WP equivalent table market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter S355J2WP equivalent table steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.

The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of S355J2WP equivalent table, alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
