A steel shaft is a rebar-like section of stainless steel that is responsible for power transmission in industrial machinery. This part can be considered as one of the important parts used in the industry because it must have features that make the product work with high reliability and not cause the devices to fail in the long run. Steel shaft is made of stainless steel alloy ingots.
Different alloys can be used to make the shaft, but the use of stainless steel can be one of the suitable options for making the shaft due to the very good characteristics of these alloys. In general, steels can be divided into four categories. Carbon steels, alloy steels, tool steels and stainless steels. These four categories have different characteristics that cause their different uses. Among these four steel groups, steel shaft can be one of the suitable options for some technical applications.
Steel shaft has good resistance to corrosion and high strength, which has made the use of steel in shaft construction common for use in corrosive environments. All types of stainless steel alloys have at least 10.5% chromium in their structure, which causes very good resistance to corrosion. Chromium can form a corrosion-resistant oxide layer on the surface of steel, which shows excellent resistance to corrosive substances and oxygen. Most importantly, the corrosion-resistant chromium oxide layer has the ability to self-repair and is formed again in case of surface wear.
