In today's SA573 Grade 70 carbon steel structural 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 SA573 Grade 70 carbon steel structural market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

S50C steel characteristics: the carbon content of the steel (mass fraction, %) ≥ 0.4, excellent wear resistance, reduced ductility, easy to deform and crack after quenching, so quenching is extremely important, and it must be quenched after cutting and tempering to avoid tempering brittleness. By implementing spheroidizing treatment, the cutting performance of this type of carbon steel keyword} can be improved. The steel is usually used after tempering to a hardness of 19~22HRC to increase its cutting performance.

The application of AR400 abrasion resistant steel plate: SA573 Grade 70 carbon steel structural, AR400 abrasion resistant steel plate is mainly for wear exposed structures use, such as protective pads, shell walls for prospectors and bulldozers. AR400 abrasion resistant steel plate is also used to fabricate the supporting or reinforcing plate, the cutting plate for truck rollover, mixing elements and conveying elements, chute grooves, machine tools, crushers and shredders, waste briquetting presses, blades, paving abrasives and agricultural machinery.

The principle of stainless steel, the corrosion resistance of SA573 Grade 70 carbon steel structural, stainless steel depends on chromium, it depends on a very thin, solid and fine stable chromium rich oxide film (protective film) formed on its surface, to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the corrosion resistance.

Q355B steel and SA573 Grade 70 carbon steel structural steel
Both Q345B and Q355B are low alloy steels. The difference is that the yield strength of Q345B low alloy steel and Q345B low alloy steel is different. In Q345B low-alloy steel, q represents the yield strength of this material, and the latter 345 represents the yield value of this material is around 345mpa. Q in Q355B low-alloy steel also represents the yield strength of this material, and the latter 355 indicates that the yield value of this material is around 355mpa.

We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes.
