Mô tả
7Cr17MoV steel is a Chinese GB standard Martensitic stainless steel grade produced by adding a small amount of molybdenum (Mo) and vanadium (V) to 7Cr17 to improve hardness and wear resistance. Similar international steel grades are US AISI 440A and Japanese SUS 440A. Mainly used for making high-hardness, high-wearing medium and high-grade knife and scissors products and medical equipment. The steel grade is widely used in knife and scissors products, including the internationally renowned brand VICTORINOX Swiss Army Knife. 7Cr17MoV steel composition is given in the following table.
