Easily Form Shapes, with Mild Steel

mild steel part 1(1)

CNC machining of mild steel involves using the latest and most advanced machines of DEK to shape and cut mild steel components precisely.

Starting with a digital design, the process includes securing the steel workpiece on the CNC machine, selecting appropriate tools, and creating a CNC program that guides the machine's movements. Operations like milling, turning, and drilling are done to shape the part, with ongoing quality checks to ensure accuracy. The choice of cutting parameters influences the surface finish, and after machining, the components may undergo deburring and finishing. The final parts are inspected for quality before being used in various industries.

TECHNOLOGY OVERVIEW

Mild Steel in CNC Machining

What is Mild Steel?

Mild steel, also known as low-carbon steel, contains a relatively low percentage of carbon (around 0.05-0.25%). This makes it softer and more ductile compared to higher carbon steels. It typically consists of iron and small amounts of manganese, sulfur, phosphorus, and other elements. Key characteristics of mild steel include its moderate strength, affordability, weldability, machinability, and formability.

Mild steel is often used to create structural elements, such as beams and columns, as well as in the production of sheet metal, pipes, and wires. It can undergo various fabrication processes like welding, bending, and cutting. However, mild steel is susceptible to corrosion, so protective coatings or treatments are applied in certain applications to enhance its durability.

Advantages of Mild Steel

  • Cost-effective
  • Versatile
  • Ductile
  • Easily machinable
  • Recyclable
  • Good strength-to-weight ratio

Applications of Mild Steel

  • Automobile chassis
  • Storage tanks
  • Pipes and tubing
  • Nails and screws
  • Appliances
  • Structural components in buildings
  • Agricultural equipment

FAQ

Machining Mild Steel Buying FAQ

Mild steel is not categorized as exceptionally strong when compared to high-strength steel alloys like tool steel or alloy steel. The lower carbon content contributes to its malleability and ease of fabrication.
Yes, mild steel is susceptible to rusting. The presence of iron and the lack of protective elements make it prone to corrosion, especially in environments with moisture and oxygen. To prevent rust, coatings or treatments such as galvanization are often applied.
Mild steel is durable and can withstand a range of mechanical stresses. However, under extreme loads or impacts, it can break. The specific conditions leading to breakage depend on factors like thickness, temperature, and the nature of the applied force.
Mild steel is not considered bulletproof. Bulletproofing requires materials with specific properties like high hardness, strength, and energy-absorbing capabilities. Steel alloys used for ballistic protection, such as AR500 or AR550, are significantly harder and tougher than mild steel to resist penetration from bullets effectively.
