Martensitic stainless steel. Chapter Four Stainless Steel 316 Grades and Properties. When compared with other stainless steel, the martensitic stainless group have a relatively high carbon content (0.1 - 1.2%). What are the properties of stainless steel? Its chemistry promotes the formation and even distribution of vanadium carbides, which are harder and more effective at cutting than chromium carbides. With over 11% chromium, steel is about 200 times more resistant to corrosion than mild steel. Austenitic Stainless Steel Martensitic stainless steel List of blade materials These steels can be divided into three groups based on their crystalline structure: It is a low cost grade and can be used unhardened, hardened and highly tempered states. While regular steel does have enhanced properties of strength and hardness due to their chromium metal content, they are not as strong or as hard as stainless steel metal. Similar to 410, it contains a minimum of 12% chromium, just sufficient enough to give corrosion resistant properties. Hundred years of stainless steel know-how.
