What are the top eight NM400 steel for vehicle hot rolled plates mills in South Africa

In today's NM400 steel for vehicle 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 NM400 steel for vehicle market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

The bridge steel plate NM400 steel for vehicle 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 NM400 steel for vehicle is widely used in the manufacture of large railway bridges and highway bridges.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with NM400 steel for vehicle ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

Alloying agents like carbon and manganese along with steel lends a malleable nature to A572 structural high tensile steel plates, NM400 steel for vehicle, letting them be formed into various structurals that adapt quickly to constantly evolving needs of an edifice, thereby being flexible to changes. High tensile steel plates facilitate an increased load bearing capacity; their lighter bodies handle the extra weight without giving in to pressures. Heavy lifting and moving vehicles built from them increase weight bearing capacity, reduce time and labour cost to increase profits.

As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of NM400 steel for vehicle, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate NM400 steel for vehicle EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
