40Cr alloy belongs to gb3077 "alloy structural steel". The carbon content of 40Cr steel is 0.37% ~ 0.44%, which is slightly lower than that of 45 steel. The content of Si and Mn is equivalent, and the content of Cr is 0.80% ~ 1.10%. In the case of hot rolling supply, the 1% Cr basically does not work, and their mechanical properties are roughly the same. Because the price of A709 grade 50W structural steel sheet is about half of that of 45 steel, 40Cr is not needed for the purpose of economy.
Steel transportation because of the special material of A709 grade 50W structural steel sheet steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
