The concept of steel: Steel is an alloy of iron, carbon, and a small number of other elements. Steel is an ingot, billet, or steel that has been press-worked into the shapes, sizes, and properties we need. Steel is an essential material for national construction and the realization of the four modernizations. It is widely used and has a wide variety. According to the different cross-sectional shapes, it is generally divided into four categories: profiles, plates, pipes, and metal products. To facilitate the production and ordering of steel Supply and do a good job in operation and management, it is divided into heavy rail, light rail, large section steel, medium section steel, small section steel, cold-formed section steel, high-quality section steel, wire rod, medium and thick steel plate, thin steel plate, electrical silicon steel sheet, strip steel, no Seam steel pipe, welded steel pipe, metal products, and other varieties.
Steel is an alloy of iron, carbon, and small amounts of other elements. Stainless steel or corrosion-resistant alloy steel with 10.5% or more chromium-gold content is a generic term for this type of metal. It should be remembered that stainless steel does not mean that the steel will not rust or corrode, but simply that it is much more resistant to corrosion than alloys that do not contain chromium. In addition to chromium metal, other metal elements such as nickel, molybdenum, vanadium, etc. can also be added to the alloy to change the properties of the alloy steel, thereby producing stainless steels of different grades and properties. A careful selection of knives made of stainless steel with the most appropriate properties, depending on the purpose and location of the application, is critical to improving the efficiency and probability of success for a given job. Advantages of different metal elements in knives. Simply put: Steel is an alloy of iron and carbon. The other ingredients are there to differentiate the properties of the steel. The important steels are listed below in alphabetical order, and they contain the following ingredients:
Carbon – Present in all steels and is the most important hardening element. To help increase the strength of the steel, we usually want knife-grade steel to have more than 0.5% carbon, also high-carbon steel.
Chromium – Increases wear resistance, hardness, and most importantly corrosion resistance, with over 13% considered stainless steel. Despite its name, all steel will rust if not maintained properly.
Manganese (Manganese) – an important element that contributes to the creation of textured structure, and adds firmness, strength, and wear resistance. Internal deoxidation of steel during heat treatment and crimping is found in most knife and shear steels except A-2, L-6, and CPM 420V.
Molybdenum (Molybdenum) – carbonizing agent, prevents the steel from becoming brittle, maintains steel strength at high temperatures, occurs in many sheets of steel, air hardening steels (eg A-2, ATS-34) always contain 1% or more Molybdenum so they can harden in the air.
Nickle – Maintains strength, corrosion resistance, and toughness. Appears in L-6\AUS-6 and AUS-8.
Silicon – Helps increase strength. Like manganese, silicon is used to maintain the strength of steel during its production.
Tungsten (Tungsten) – Enhances abrasion resistance. A mixture of tungsten and an appropriate proportion of chromium or manganese is used to make high-speed steel. A large amount of tungsten is contained in the high-speed steel M-2.
Vanadium – Enhances wear resistance and ductility. A carbide of vanadium is used to make striped steel. Vanadium is contained in many kinds of steel, among which M-2, Vascowear, CPM T440V, and 420VA contain a large amount of vanadium. The biggest difference between BG-42 and ATS-34 is that the former contains vanadium.
