Processing performance of quenched and tempered steel: a573 gr.65 carbon-manganese-silicon steel plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.
"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and a573 gr.65 carbon-manganese-silicon steel product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. a573 gr.65 carbon-manganese-silicon 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).
