Iron is a soft, silvery metal that is the fourth most abundant element in the Earth's crust. Pure iron is of limited use, but once it is made into an alloy (ferric alloys), it will be a material with great application potential. Ferric alloys, a large and widely used class of hard surface materials, are metals that consist mostly of iron, in which metal alloying elements are deliberately added to form substitutional solid solutions, and all strengthening effects caused by non-metallic carbon are secondary. The biggest characteristic of this kind of material is that the comprehensive performance is good, the performance range is wide and the material price is the low. Today, with the cheap price and reliable properties, ferric alloys have become one of the most used materials in the world and are an indispensable material of construction industry, manufacturing industry and people's daily life. It is no exaggeration to say that the ferric alloys are the foundation of modern society.
Types
There are a number of different types of ferric alloys. Some of the most important include stainless steels, carbon steels, cast iron, tool steels, manganese steel.
- Stainless steels: Stainless steels are steels that contain chromium (10-30%), nickel (0-20%), and iron. Other elements such as molybdenum, titanium, and copper may also be added. There are many types and grades of stainless steels, but the most common grade used for typical corrosion resistant applications is type 304, also known as 18-8. In addition, it is worth mentioning that super austenitic stainless steel and duplex stainless steel have become the typical representatives of stainless steels because of their excellent properties.
- Carbon steels: Carbon steels are steels in which the main alloying additive is carbon. Mild steel is the most common due to its low cost. It is neither brittle nor ductile, has relatively low tensile strength, and is malleable.
- Cast iron: Cast iron is an iron alloy derived from pig iron, alloyed with carbon and silicon. Cast iron is often dismissed as a cheap, brittle metal.
- Tool steels: Tool steels are particular steels designed for being made into tools. They are known for toughness, resistance to abrasion, ability to hold a cutting edge, and / or their resistance to deformation at high temperatures. The three types of tool steel available are cold work steels, hot work steels and high speed steels.
- Manganese steel: Manganese steel, also known as high manganese steel, contains Mn 12% to 15% and Cr, Ni, Mo, and the austenite structure is stabilized by manganese. It can withstand high impact and slight to moderate abrasive wear.
