ASTM A572 Grade 50, used in large-scale construction, S420MC cold forming is an extremely strong alloy with a yield strength of 65,000 psi, an allowable bending stress of 39,000 psi and a future as the high-performance replacement of ASTM A36 steel.

Corrosion resistant steel prices are generally higher. What are the applications of S420MC cold forming, corrosion resistant steel? First, the corrosion resistant steel can be used in chemical containers, such as furnaces. Some chemical products have strong corrosivity and need steel with excellent corrosion resistance, otherwise they will be easily corroded. Second, the corrosion resistant steel can be used for sewage pipelines. Industrial sewage pipelines need to discharge a large amount of wastewater, which may contain harmful substances.

The main function of boron in S420MC cold forming and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. S420MC cold forming, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
