Rolling technology of S355ML material equivalent standards

The bridge steel plate S355ML material equivalent standards produced by BBN company has pure steel, flat and smooth plate surface, small difference between plates, -40 ℃ impact value and aging impact value are stable, and the margin is large. Bridge steel plates can be controlled by rolling, cooling, normalizing, and tempering organize production with different production processes. This bridge steel S355ML material equivalent standards is widely used in the manufacture of large railway bridges and highway bridges.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, S355ML material equivalent standards based on a high starting point and high technology, the company has vigorously developed various steel products S355ML material equivalent standards and deep-processed parts, steel structures, precision castings, seamless pipes.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of S355ML material equivalent standards structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

Vanadium mainly exists in the form of carbide in S355ML material equivalent standards and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent S355ML material equivalent standards products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the S355ML material equivalent standards technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
