Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. A572 grade 60 CS steel carbon plate, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
Corrosion resistance mechanism of A572 grade 60 CS steel carbon plate, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
Turkey produced 8.97 million metric tons of crude steel in the first quarter, with a 9.6 percent increase from the same month of last year. Iran's crude A572 grade 60 CS steel carbon plate steel production in March amounted to 6.75 million mt. up by 13.2 percent year on year. The CIS registered a A572 grade 60 CS steel carbon plate crude steel output of 25.15 million mt. falling by 0.6 on year-on-year basis, with Russia producing 17.9 million mt, down by one percent, and Ukraine producing 5.32 million mt, falling by 3.4 percent, both on year-on-year basis.
