High-quality alloy steel is made of high-quality carbon structural steel by adding one or several alloying elements (the total mass fraction does not exceed 5%). The alloying elements contained are of different types and contents, and the corresponding properties are also different. High-quality alloy steel is mainly used to manufacture various parts that are larger in size, more complex in shape and difficult to meet performance requirements with high-quality carbon steel. Through proper heat treatment, CCS A40 bulk ore carrier steel, high-quality alloy steel can obtain higher strength and toughness.
After quenching and tempering, 40Cr alloy steel plate and CCS A40 bulk ore carrier steel sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel CCS A40 bulk ore carrier steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the CCS A40 bulk ore carrier steel steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of CCS A40 bulk ore carrier steel seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
