Low-temperature impact of 16MnCr5 and 20MnCr5 16MnCr5 and 20MnCr5

Thread Content

16MnCr5 and 20MnCr5 are carburizing steels from Germany; they are somewhat similar to China’s 15CrMn steel, but their mechanical properties are superior to those of 15CrMn steel. They possess good hardenability and machinability. For parts with larger cross-sections, heat treatment enables high surface hardness and wear resistance, as well as high low-temperature impact toughness. 　　Wuyang Iron and Steel Co., Ltd. is currently capable of producing steel plates of the 16MnCr5 and 20MnCr5 grades. The thickness of these plates can range from 8 to 100 mm, the width from 1600 to 4020 mm, and the length from 6000 to 18500 mm. The minimum order quantity is 50 tons; however, smaller orders may be accepted depending on the actual circumstances. The delivery condition for 16MnCr5 and 20MnCr5 steel plates is normalized + tempered ； It can also be delivered in a tempered state according to the customer’s requirements. 　　Chemical composition of 16MnCr5 and 20MnCr5:
For 16MnCr5, the element names and their respective contents are as follows: CSiMnPSCr – 0.14~0.19, ≤0.40; 1.00~1.30, ≤0.025; ≤0.035; 0.80~1.10.
For 20MnCr5, the corresponding values are: 0.17~0.22, ≤0.40; 1.10~1.40, ≤0.025; ≤0.035; 1.00~1.30.
