What Are Ferrous Metals?

Metal is a substance that has gloss, good electrical conductivity, thermal conductivity, and mechanical properties, and has a positive temperature coefficient of resistance. Metal is a big family, and now there are 86 kinds of metals in the world. Generally, people divide metals into ferrous metals and non-ferrous metals according to their color and properties. Ferrous metals mainly refer to iron and its alloys, such as steel, pig iron, iron alloys, and cast iron. Metals other than ferrous metals are called nonferrous metals.

Ferrous materials are industrially correct

The names ferrous metal and non-ferrous metal are often misunderstood, thinking that ferrous metal must be black, in fact

Iron is a chemical element and is the most commonly used metal. It is a kind of transition metal. Iron is active, strong reducing agent, valence is

definition

Steel is a material such as steel ingots, billets, and other shapes, sizes, and properties that are required for daily use through pressure processing.

steel

Steel is an iron-carbon alloy with a carbon content between 0.04% and 2.3%. (Theoretically, the carbon content is less than 2.11% is called steel.) In order to ensure its toughness and plasticity, the carbon content generally does not exceed 1.7%. In addition to iron and carbon, the main elements of steel are silicon, manganese, sulfur, and phosphorus.

Classified by quality

(1) Ordinary steel (P0.045%, S0.050%)

(2) High-quality steel (both P and S 0.035%)

(3) High quality steel (P0.035%, S0.030%

Classified by chemical composition

(1) Carbon steel: a. Low carbon steel (C0.25%); b. Medium carbon steel (C0.25 ~ 0.60%); c. High carbon steel (0.60% C2.11%).

(2) Alloy steel: a. Low alloy steel (total content of alloy elements 5%); b. Medium alloy steel (total content of alloy elements is 5 ~ 10%); c. High alloy steel (total content of alloy elements> 10) %).
