C: 0.38～0.45 Si:0.17~0.37 Mn:0.50~0.80 Cr: 0.90～1.20 Ni:≤0.30  P:≤0.035  S:≤0.035  Cu:≤0.030  Mo: 0.15～0.2540Cr and other alloy structural steels are suitable for shaft parts with medium precision and high speed. After quenching, tempering and quenching, these steels have better comprehensive mechanical properties. After quenching and tempering, this kind of steel is used to make mechanical parts which can bear medium load and medium speed, such as steering knuckle, rear half shaft of automobile, gear, shaft, worm, spline shaft and top sleeve of machine tool.1,Our company has a large number of inventory, can meet your needs in time.2, provide relevant information in time according to the customer's demand to ensure the quantity and quality of products.3、Relying on the country's largest steel market, one-stop with all the products you need to save costs for you.
