1. Carbon steel

Carbon steel is one of the most common mechanical processing materials due to its low price and good processability. It has high hardness and strength, and is not easily deformed, making it suitable for producing large quantities of parts and components. Carbon steel is divided into low carbon steel, medium carbon steel, and high carbon steel according to its carbon content.

2. Alloy steel

Adding various alloying elements such as chromium, molybdenum, nickel, etc. to alloy steel can improve the hardness, toughness, and corrosion resistance of the steel. Therefore, in the manufacturing of mechanical parts that require higher performance, alloy steel is often used. Alloy steel can be subdivided into various types such as chromium molybdenum alloy steel, chromium molybdenum steel, manganese molybdenum steel, etc.

What are Benefits in CNC Carbon Steel Machining?

Carbon steel is a high-quality metal material with high hardness and strength, widely used in metallurgy, mechanical manufacturing, shipbuilding, automotive and other fields. In terms of processing, carbon steel is one of the more easily processed metal materials, with the following processing properties:

1. Easy to cut: Carbon steel has good cutting properties and chips are easily formed during the machining process.
2. Easy to weld: Carbon steel can be welded using various welding methods such as arc welding, gas welding, and laser welding at room temperature.
3. Easy cold processing: Carbon steel can be subjected to cold processing such as compression, stretching, and bending, with lower processing difficulty.
4. Easy to heat treat: Carbon steel can also undergo heat treatment, such as flame quenching, carburization, etc., to enhance the hardness and strength of the material.

Anyway, carbon steel is easy to go rust in the air so we usually need to do surface treatment for longer service like powder coating, plating etc. Shanghai Yixing Machining happens to provide different kinds of surface treatment. You don’t need to look for surface treatment supplier for your special project.

What Are the Characteristics of Alloy Steel?

Alloy steel is a type of steel that contains a certain amount of alloying elements (excluding carbon) and has wide applications in industrial and manufacturing fields, such as aviation, automotive, shipbuilding, energy, etc. It has advantages in strength, corrosion resistance, and thermal stability, but it also results in higher manufacturing costs

High Strength: The alloying elements in alloy steel can increase strength in ordinary steel. Especially at high temperatures, alloy steel exhibits higher strength and toughness.

Corrosion resistance: The alloying elements in alloy steel can improve its corrosion resistance, especially in harsh environments. For example, stainless steel is a highly corrosion-resistant alloy steel.

Good Thermal Stability: The alloying elements in alloy steel can improve its thermal stability, enabling it to work at high temperatures, such as in high-temperature components such as automotive engines and aviation engines.

Easy To Machine: The machining performance of alloy steel is similar to that of ordinary carbon steel, and it can be processed through various methods such as milling, drilling, turning, stamping, etc.
Expensive: Due to the high cost of alloying elements in alloy steel, its manufacturing cost is higher and its price is also higher than ordinary steel.

FAQs

What is the difference between low-carbon steel and alloy steel?

1.Composition differences
The carbon content of low-carbon steel is generally below 0.05%, and its main alloying elements are iron and carbon. In addition, it also contains elements such as manganese, silicon, and phosphorus. In addition to iron and carbon, alloy steel also contains other alloying elements such as titanium, chromium, nickel, etc. to improve its specific properties. Therefore, the composition of alloy steel is more complex than that of low-carbon steel.
2.Nature differences
Low carbon steel is usually easier to process and form than alloy steel because of its lighter weight, lower hardness, strength, and corrosion resistance. Alloy steel, on the other hand, has higher heat resistance, hardness, and strength, making it suitable for use in high temperature, high pressure, and highly corrosive environments.
3.Application differences
Due to its good processability and affordable price, low-carbon steel is widely used in light industries such as construction, automotive, and aviation. Alloy steel is suitable for the production of high-speed tool steel, wear-resistant steel, stainless steel and other industrial fields.
4.Advantages and disadvantages analysis
The advantages of low-carbon steel are good processability, low price, and suitability for large-scale production. Its disadvantages are low hardness and strength, making it unsuitable for applications with high strength requirements. The advantages of alloy steel include good hardness, strength, and corrosion resistance, making it suitable for situations with high strength and durability requirements. Its disadvantage lies in its high price and complex manufacturing process.
What is the Difference Between Steel and Aluminum CNC Machining?

1.Different Machining Processes
Aluminum is soft so it is prone to damage. Smaller cutting forces and speeds are required during machining to avoid scratches on the surface. Steel has a certain degree of hardness and toughness. Lager cutting forces and faster cutting speeds can be used during machining for higher efficiency.
Aluminum has better thermal conductivity so it requires higher coolant circulation rate while steel has poor thermal conductivity so local heating is need during machining.

2.Different Physical Properties
Aluminum has good thermal and electrical conductivity, as well as good corrosion resistance. Steel, on the other hand, has high hardness, strength, and toughness. These different physical properties determine they will be suitable for different applications.

3.Applicable Scenarios Vary
Generally speaking, aluminum parts are suitable for lightweight, high strength, and high reliability products, such as aviation, automotive, and electronics, while steel is suitable for areas with high requirements such as friction and wear resistance, such as construction, machinery, and shipbuilding.
What is The Difference Between Metal Hot Working and Cold Working?

1.Different Temperature
Cold working is carried out below the crystallization temperature of a metal, while the metal remains in its original lattice structure; Hot working is carried out above the crystallization temperature of the metal, and the metal is in a plastic state.

2.Different Deformation
During cold working, metal materials undergo work hardening during plastic deformation, resulting in an increase in dislocation density and an increase in material strength and hardness; During hot working, crystals may undergo recovery and recrystallization processes while undergoing deformation, leading to changes in microstructure and potentially improving the toughness, corrosion resistance, and weldability of the metal.

3.Different Application
Cold working is suitable for manufacturing high-precision and high surface quality metal products, such as stretching, extrusion, cold rolling, cutting, cold drawing, bending, etc; Hot working is suitable for manufacturing large-sized and special shaped workpieces, such as forging, rolling, extrusion, forging stone, quenching, and tempering.

In summary, cold working is suitable for high-precision and high demand metal product processing at room temperature, while hot working is suitable for manufacturing large-sized and special shaped workpieces. For metals of different materials, cold or hot working processes should be selected based on their own properties to maximize their advantages.
