HM Steel Machining Parts

One of the materials that are most frequently used in CNC machining is steel. Iron is the primary component of steel. Steel can be combined with other elements (elements such as chromium, nickel, copper, and more) in different amounts to produce different types of steel. Alloying elements are added to acquire unique characteristics such as extreme temperature stability, corrosion resistance, hardness, etc. There are more than 1000 varieties of steel compositions. However, they are divided into 4 main types such as carbon steel, alloy steel, stainless steel, and tool steel.

HM offers steel parts manufactured in accordance with your requirements. We can provide milling, turning, and other machining services using our high-precision and advanced CNC machines.

Steel Parts by Materials

  • Stainless Steel

    Stainless steel is used for producing bolts, bushings, screws, nuts, electronic hardware, automotive parts, and more. It has excellent corrosion resistance, weldability, and machinability.

  • Mild Carbon Steel

    Machinery parts, anchor pins, tie rods, and carburized parts can be made from mild carbon steel. Mild carbon steel has excellent strength, weldability, ductility, and machinability.

  • Medium Carbon Steel

    Medium carbon steel parts are commonly used for wear-resistant applications. Some of the medium carbon steel parts include light gears, bolts, axles, forged connecting rods, and more.

  • Low Alloy Steel

    Machinery parts, automotive parts, nuts, couplings, spindles, piston pins, gears, fasteners, bolts, chains, and chains can be made from low alloy steel.

Steels Suitable for Machining

Carbon Steels
Carbon Steels

Carbon steels are easy to machine. They are composed of about 2-3% carbon. After machining carbon steel parts, they will undergo a heat treatment to reduce weathering and corrosion. We can machine different grades of carbon steels such as:

  • High: 1080
  • Medium: 1040 and 1030
  • Low: 1018 and 1010
Alloy Steels
Alloy Steels

Alloy steels are made by adding varying amounts of extra elements to the carbon steel. Different kinds of elements can be added such as nickel, manganese, copper, calcium, silicon, and many more. This will result in a steel that has additional physical properties not present in standard carbon steel. Alloy steels have increased corrosion resistance, strength, and hardness. Some of the alloy steel grades we can machine include:

  • 4130
  • 4340
  • 4140
Stainless Steels
Stainless Steels

Stainless steels are steels that have up to 10 to 20% chromium added. They are highly resistant to rust and have visual appeal. The stainless steel grades we can machine are:

  • 316
  • 304
  • 303
Tool Steels
Tool Steels

Tool steels are a class of alloys and carbon steels. There are six different types of tool steels such as shock-resistant, water-hardened, high-speed, air hardened, special purchase, and hot work. We can machine:

  • A582
  • A286
  • A277
  • “We are really grateful for your prompt response on my inquiries. HM is really an expert in machining steel parts. Also, I want to thank you for your support, high-quality steel parts, and services.”

Which Steel is the Easiest to Machine?

303 stainless steel is the easiest to the machine. They are the top choice for machining fasteners, gears, fittings, and other applications that need tight tolerances.

Which Type of Steel is Difficult to Machine?

High carbon steel is hard to machine since they have high carbon content that makes them extremely strong. They are also one of the least ductile and hardest steels.
