about carbon steel

Carbon steel is one of our most commonly used metals. It is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%, also called carbon steel.


Generally, the higher the carbon content of carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.


According to the application requirements of different industries, carbon steel is divided into three types: low carbon steel, high carbon steel, and medium carbon steel. Each type of carbon steel has different strength and application industries.


Through bending forming, stamping, milling, cutting, welding, etc., products such as pipes, steel structural parts, chains, screws, boxes, cabinets, standard parts, hammers or screwdrivers can be produced.

Why Choose Mulan MFG

Carbon steel Style

The most popular performance of stainless steel is corrosion resistance, which reduces the effect as the carbon content increases, so maintaining a low carbon level is one of the main advantages of stainless steel.

Application of custom stainless steel parts

Reasonable surface treatment of metal parts can improve the durability, corrosion resistance, heat resistance, electrical conductivity and appearance decoration of the material.

Carbon tool steel

The steel grade is expressed in terms of the average mass percent of carbon element content, and is prefixed with T.

Such as T9, T12, etc.

Uses: Mainly used to manufacture various cutting tools, molds, measuring tools, etc.

High-quality carbon structural steel

Steel grade is expressed by the average mass per thousand of carbon content.

20#, 45#, etc.

Uses: Mainly used in the manufacture of various machine parts.

Ordinary carbon structural steel

Carbon structural steel is divided into 5 grades according to the yield strength of steel: Q195, Q215, Q235, Q255, Q275. Each grade is divided into A, B, C, D grades due to different quality.

Q195, Q215, Q235 have good plasticity and can be rolled into steel plates, steel bars, steel pipes, etc.

Q255, Q275 can be rolled into section steels, steel plates, etc.

Cast steel

The grade of cast steel is prefixed with ZG in front of the number.

Uses: Mainly used to manufacture parts with complex shapes and requiring certain strength, plasticity and toughness, such as gears, couplings, etc.

Application of custom carbon steel parts

  • Increase strength
  • Increase carburizing capacity
  • Low cost metal
  • Fully recyclable and reusable for sustainable processing


This is a leaded steel that is very suitable for machining. Can be processed and reduce tool wear.


Leaded steel is also an excellent choice for improving machinability and reducing tool wear.

AISI 1117

Good choice for hardenability. Suitable for parts that require heat treatment due to the addition of manganese.

AISI 1018

This material is very suitable for carburized parts and has good weldability.

AISI 1045

Very suitable for bolts, nuts, shafts. It is a medium carbon steel and is not suitable for hot-dip galvanizing.

AISI 1141

For surface hardening, this material is one of the best materials. It can be processed to a higher surface hardness than 1045 or 1018.

AISI 1144

Suitable for machining. Not suitable for welding.
