Press Brake

For sheet metal bending, the press brake is a necessary machine. We have NC type and CNC type press brakes. At the same time, we can customize the punches and dies according to your practical use in sheet metal fabrication.

Shearing Machine

For the straight cutting of steel plate, hydraulic shearing machine is a good choice. It not only has high cutting efficiency, but also requires less investment. We have both swing beam shears and guillotine shears for your selection.

Laser Cutting Machine

In the current metal plate and pipe cutting, laser cutting machine is undoubtedly the best choice. It can not only cut various shapes, but also has small cutting gap, high precision and high cutting efficiency. Today, it is very cost-effective.

30+ Different Types of Steel (7 Classification Method)

Types of metals

First, let’s see the definition of metal.

Definition of metals from Wikipedia:

A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well.

Then how many types of metals are there?

Let’s dive right in.

Generally, metals can be divided into two categories: ferrous metal and nonferrous metal.

ferrous metals and non ferrous metals

Ferrous metal (Black metal)

Alloys based on iron, manganese and chromium are usually referred to as ferrous metals. Iron-based alloys are called steel.

Ferrous metal

Non-ferrous metal

Alloys based on the remaining alloys are referred to as non-ferrous metals. Non-ferrous metals are usually named after their element names. Such as aluminum and aluminum alloys, copper and copper alloys.

Non-ferrous metal

Classified by the smelting process

Steel can be divided into:

  • Hand furnace steel
  • Electric furnace steel
  • Converter steel

Converter smelting

And electric furnace steel can be divided into:

  • Electric arc furnace
  • Induction furnace
  • Vacuum induction furnace
  • Electroslag furnace

Crucible type high frequency induction furnace

Classified by the degree of deoxidation

  • Rimmed Steel (Q235AF)
  • Killed steel (Z)
  • Semi-killed steel (b)
  • Special killed steel (TZ)

Rimmed Steel

Classified by application

Steel can be divided into:

  • Structural steel
  • Tool steel
  • Special performance steel

Specifically, structural steel can be further divided into:

  • Building structural steel
  • Machine manufacturing steel

Tool steel can be divided into:

  • Measuring tool steel
  • Cold mold tool steel
  • Hot mold tool steel

Hot mold tool steel

Hot mold tool steel

Special property steel can be divided into:

  • Impact resistant low-temperature steel
  • Stainless acid resistant steel
  • Weathering resistant steel
  • Electrical steel

Electrical steel

Electrical steel

Classified by the metallographic structure

(1) According to the equilibrium state and the annealed structure, it is divided into: hypereutectoid steel, eutectoid steel, hypereutectoid steel and lysitic steel.

(2) According to the normalizing structure, it is divided into: pearlitic steel, bainite steel, martensitic steel and austenitic steel.

(3) According to the metallographic structure of the heating phase with or without phase change, it is divided into: ferritic steel, austenitic steel, martensitic steel, and duplex steel.

Classified by the chemical component

Carbon steel is divided into:

  • Ordinary carbon steel
  • High-quality carbon steel
  • Advanced carbon steel

Ordinary carbon steel

Alloy steel is divided into:

  • Low-alloy steel
  • Medium alloy steel
  • High alloy steel

Alloy steel

Alloy steel

Carbon steel:

Also been called mild steel. In addition to iron and carbon, it mainly contains a small amount of impurities like Si, Mn, S, P etc. The total content is not more than 2%. According to the carbon content, it is divided into:

  • Low carbon steel – less than 0.25% carbon
  • Medium carbon steel – carbon content 0.25 ~ 0.6%
  • High carbon steel – carbon content greater than 0.6%

Alloy steel:

In addition to the elements contained in carbon steel, there are other alloying elements such as Cr, Ni, Mo, W, V, B. According to different alloying elements, it’s divided into:

  • Low alloy steel – less than 5% alloy
  • Medium alloy steel – alloy content 5-10%
  • High alloy steel – alloy content greater than 10%

Alloy Steel

Classified by quality

(1) Ordinary steel

(2) High-quality steel

(3) Premium quality steel A

(4) Special high-quality steel E

Classified by shape

Thick Plate


  • 2-4.0 mm: steel sheet
  • 4-20mm:medium plate
  • >20mm: thick plate


  • Seamless tube (hot rolled, cold drawn and pressed)
  • Seamedwelding tube (straight seam pipe, spiral tube)
