What are the five major elements of steel, and what are the eight elements of steel

The five major elements in steel materials are C (carbon), Si (silicon), Mn (manganese), P (phosphorus), and S (sulfur). The eight major elements in steel materials are C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulfur), iron, nitrogen, and oxygen. The reason for the wide range of application of steel materials is, first of all, that the available components range widely, from nearly carbon-free industrial pure iron to cast iron with a carbon content of about 4%, and the phase structure and microstructure of the alloy have undergone great changes in this range; In addition, various thermal processing techniques, especially metal heat treatment technology, can be used to greatly change the structure and properties of a certain component alloy.

Extended InformationIron-carbon alloys are divided into two categories: steel and pig iron, and steel is an iron-carbon alloy with a carbon content. Carbon steel is the most commonly used ordinary steel, which is easy to smelt, easy to process, inexpensive, and can meet the requirements of use in most cases, so the application is very common. According to the different carbon content, carbon steel is divided into low carbon steel, medium carbon steel and high carbon steel.

With the increase of carbon content, the hardness of carbon steel increases and the toughness decreases. Alloy steel, also known as special steel, adds one or more alloying elements on the basis of carbon steel to change the microstructure and properties of steel, so as to have some special properties, such as high hardness, high wear resistance, high toughness, corrosion resistance, and so on. The alloying elements that are often added to steel are SI, W, MN, CR, NI, MO, V, TI, etc.

The resources of alloy steel are quite abundant, in addition to the lack of CR and CO and the low grade of Mn, the reserves of W, MO, V, TI and rare earth metals are very high. At the beginning of the 21st century, the proportion of alloy steel in total steel production will increase significantly.

The basic element of steel is Fe, which accounts for 99% of ordinary carbon steel, in addition to carbon (C), silicon (Si), manganese (Mn) and other impurity elements, as well as sulfur (S), phosphorus (P), oxygen (O), nitrogen (N) and other harmful elements, the total content of which is about 1%. These are the eight elements!

The five elements are c si mn p s

Of course, due to the different varieties of steel, some steels have other elements such as cr ni al and so on, you can refer to the basic steel grade manual and other related materials for details.

These are the eight elements! The five elements are carbon, sulfur, manganese, phosphorus, and silicon.

Steel has carbon, chromium, manganese, silicon, tungsten elements in it.

1. Carbon. Present in all steels, it is the most important hardening element. To help increase the strength of the steel, we usually want the cutter-grade steel to have more carbon, also known as high-carbon steel. (The chant is shown in the picture below).

2. Chromium. I increase wear resistance, hardness, and most importantly, corrosion resistance, and I am considered to be stainless steel with more than 13%. Despite the name, all steel will rust if it is not made properly. (as shown in the image below).

3. Manganese. Important elements that help to create a textured structure, increase the firmness, strength, and abrasion resistance. The internal deoxidation of the steel during the hot treatment and coiling process occurs in most steel for knives and scissors. (as shown in the image below).

4. Silicon. Helps to enhance strength, and like manganese, silicon is used in the production of steel to maintain the strength of steel. (as shown in the image below).

5. Tungsten. Enhanced abrasion resistance. Tungsten is mixed with chromium or manganese in the right proportion to make high-speed steel, which contains a large amount of tungsten in high-speed steel M2. (as shown in the image below).

Iron, carbon

Steel is an iron-carbon alloy with a carbon content in between. 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. In addition to iron and carbon, the main elements of steel are silicon, manganese, sulfur, phosphorus, etc. The other components are designed to differentiate the properties of the steel.

There are all kinds of steel in life.

In junior high school chemistry, the main difference between steel and pig iron is the difference in carbon content, pig iron has a carbon content of 2%, while steel has a carbon content of in. (The minimum carbon content of junior steel is, but the reality is.)

And steel is divided into high-carbon steel, medium-carbon steel, and low-carbon steel.

1) Low carbon steel has < carbon content

2) Medium carbon steel carbon content.

3) High carbon steel carbon content.

There is no certainty, it is calculated according to the formula.

Let the steel sample be put into a sufficient amount of dilute hydrochloric acid, let the iron react completely, measure the total mass before the reaction is x, and the mass after reflection is y, measure the hydrogen mass with x-y, and then set the iron mass as z, and the column equation: 2 56=(x-y) z

Iron and oxygen are the most abundant elements in the earth's crust, and in the interior of the earth is an iron core. It is also believed that it is silicon, and in the interior of the earth's crust, the amount of silicon in the mantle is much higher than the amount of oxygen, and the earth's crust is only a thin layer.

Five elements: silicon, manganese, carbon, phosphorus, sulfur Five impurity elements: oxygen, nitrogen, phosphorus, sulfur, hydrogen.

The metal elements in the earth's crust are oxysilicone, aluminum, iron, and calcium from more to less.

What is the element, if it is in the earth's crust, it is oxysilicone, aluminum, iron, calcium.
