2-1/2 inch Q345NQR2 steel specification supplier

Low alloy structural steel, also known as ordinary low alloy steel, HSLA steel. Q345NQR2 steel specification, Low alloy steel plates are killed or semi killed steel plates. Low alloy steel plates have the advantages of high strength, better performance, saving material and reducing the weight of structure. The thickness range of low alloy steel plates is usually 4.5-200mm. Low alloy structural steel is mainly used for manufacturing bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc.According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for Q345NQR2 steel specification, 42CrMo steel is quenching and tempering.Steel transportation because of the special material of Q345NQR2 steel specification 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".
