steel | ||||||||
Steel is a general term for iron-carbon alloys with a carbon content mass percentage between 0.02% and 2.11%. The chemical composition of steel can vary greatly, and steel containing only carbon element is called carbon steel (carbon steel) or ordinary steel; | ||||||||
Introduction to Steel | In actual production, steel often contains different alloying elements according to its use, such as manganese, nickel, vanadium, and so on. The history of human application and research on steel is quite long, but until the invention of the bainite steelmaking method in the 19th century, the production of steel was a high cost and low efficiency task. Nowadays, steel has become one of the most commonly used materials in the world due to its low price and reliable performance, and is an indispensable component in the construction industry, manufacturing industry, and people's daily lives. It can be said that steel is the material foundation of modern society. | |||||||
Application of Steel | Steel can be cast into stainless steel deodorizing soap for sale. Stainless steel deodorizing soap is a special steel block made of stainless steel that never gets smaller and is used in the same way as regular soap. This stainless steel deodorizing soap comes from Germany and cannot be decontaminated, but it can deodorize hands full of fishy odor. After washing with stainless steel deodorizing soap for 30 to 40 seconds, the fishy odor can disappear. | |||||||
Definition of Steel Composition | ||||||||
Steel is an iron carbon alloy with a carbon content ranging from 0.04% to 2.3%. We usually refer to it as steel together with iron, and in order to ensure its toughness and plasticity, the carbon content generally does not exceed 1.7%. The main elements of steel include silicon, manganese, sulfur, phosphorus, etc. in addition to iron and carbon. The other components are used to differentiate the properties of the steel. | ||||||||
(Carbon) | It exists in all steels and is the most important hardening element. It helps to increase the strength of steel, and we usually hope that tool grade steel has more than 0.6% carbon, which also becomes high carbon steel. | |||||||
(Manganese) | Important elements that help generate texture structures, increase durability, strength, and wear resistance. During the heat treatment and rolling process, deoxygenation occurs inside the steel, which occurs in most knife and shear steels, except for A-2, L-6, and CPM 420V. | |||||||
(Molybdenum) | Carburization agents prevent steel from becoming brittle and maintain its strength at high temperatures. They are found in many steels, such as air hardened steel (such as A-2, ATS-34), which always contains 1% or more molybdenum, so that they can harden in the air. | |||||||
(Nickle) | Maintain strength, corrosion resistance, and toughness. Appears in L-6 AUS-6 and AUS-8. | |||||||
(Silicon) | Helps to enhance strength. Like manganese, silicon is used to maintain the strength of steel during the production process. | |||||||
(Tungsten) | Enhance wear resistance. Mix tungsten with an appropriate proportion of chromium or manganese to manufacture high-speed steel. High speed steel M-2 contains a large amount of tungsten. | |||||||
(Chromium) | Increase wear resistance, hardness, and most importantly, corrosion resistance, with over 13% considered stainless steel. Despite this, if not properly maintained, all steel will rust. | |||||||
(Vanadium) | Enhance wear resistance and ductility. A vanadium carbide used in the manufacture of striped steel. Vanadium is present in many types 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 | |||||||

The Use of Steel | ||||||||
1. Structural steel: | Structural steel for construction and engineering, abbreviated as construction steel, is used to make metal structural components in buildings, bridges, ships, boilers, or other engineering projects. Construction steel - such as various types of steel used for building grid steel structures, ships, factory structures, and other buildings, as well as ordinary steel. Steel for mechanical manufacturing - mainly used for manufacturing machines or other mechanical parts. In this type of steel, the steel with a carbon content of 0.1% -0.3% that can be used after surface carburization treatment is called carburized steel. Steel with a carbon content of 0.3% -0.6% and requiring quenching and tempering treatment is called quenched and tempered steel. Spring steel and bearing steel - mainly used for manufacturing mechanical equipment parts, so they are commonly classified as structural steel for mechanical manufacturing. However, each of these two types of steel has a specific purpose and has a relatively high carbon content, so they are often classified separately. |
