A573 Grade 70 rolled structural steel considered mild steel?

Based on the main A573 Grade 70 rolled structural steel business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel A573 Grade 70 rolled structural steel products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Precautions for procurement of A573 Grade 70 rolled structural steel, corrosion resistant steel. First, thickness. According to the thickness, corrosion-resistant steel can be divided into thin plate, medium plate, thick plate and extra thick plate, and each thickness has different application fields. Second, the choice of length and width, which can be cut to required size. Third, standards, each country has its own standards, so when purchasing corrosion resistant steel, it depends on which country it is used. Fourth, it is better to let professionals to purchase A573 Grade 70 rolled structural steel or corrosion resistant steel.

The advantages of A573 Grade 70 rolled structural steel, carbon steel: First of all, the price of carbon steel is low. Compared with stainless steel, galvanized steel, alloy steel, etc., the carbon steel has a great advantage in price. It is a good choice for manufacturers and merchants such as construction sites that use building materials in large quantities. Secondly, the carbon steel is easy to process. In the early days, steelmaking technology was underdeveloped. It was very difficult to manufacture high-precision steel, and carbon steel is widely used.

The effect of alloy elements of A573 Grade 70 rolled structural steel, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. A573 Grade 70 rolled structural steel, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
