Stainless Steel Machining

Stainless steel is an alloy that comprises mainly Iron with at least 10.5% of Chromium plus various other ingredients. Although we talk of stainless steel as a single material, there are various types, and they all have different properties.

Stainless Steel — A Popular & Versatile Material

Stainless steel has many properties that make it a popular choice for many applications. It has a high resistance to corrosion, withstands high temperatures and pressures, has an exceptional appearance, is easy to keep clean and is extremely strong.

It’s particularly used in the food processing, water treatment and pharmaceutical industries where it meets stringent hygiene requirements. But it does need to be machined correctly to create effective components and, at Amiga Engineering, we have the knowledge and experience to undertake precise stainless steel machining.

Using The Correct Stainless Steel Variety For Our Machining Solutions

  • Austenitic stainless steel is the most common type and has Nickel, Nitrogen and Manganese added to make welding and forming much easier. The Nickel gives it more resistance to stress corrosion cracking and the steel can be work-hardened to increase strength and pliability. Depending on composition and hardening, the metal can be slightly magnetic.
  • Ferritic stainless steel contains more Chromium, which makes it less prone to stress corrosion cracking but also less pliable and capable of being formed. Carbon is also present while adding Molybdenum makes the metal suitable for use in sea water and other harsh conditions. This type of steel is magnetic, loses some of its toughness when welded and can’t be hardened by heat treatment.
  • Duplex stainless steel is an equal mix of the previous two types, which means it’s more resistant to stress corrosion cracking, stronger and magnetic.
  • Martensitic stainless steel has a high level of Chromium and more Carbon than Ferritic steel. As a result, it can be hardened and tempered, has high strength and moderate resistance to corrosion. It’s magnetic and not normally recommended for forming or welding.
  • PH (Precipitation Hardening) stainless steel is heat treated to give high strength, which is intensified by adding elements such as Aluminium and Copper. As a result, it can be machined into complex shapes with no distortion and has the same corrosion resistance as Austenitic. Read More

Achieving The Best Results With The Right Machining For Your Stainless Steel Product

Depending on where and how you will use stainless steel components, we’ll choose the most appropriate type of material for the job. This will be influenced by the type of application, the degree of strength and toughness needed, hygiene requirements and whether the appearance is important.

Here at Amiga Engineering solutions we have the experience and knowledge in design and manufacturing, combined with the equipment we have available, mean we can offer various stainless steel machining options:

  • mill turning to achieve various shapes
  • boring for pipes, cylinders and assemblies
  • threading to create screw threads
  • burnishing to provide a good looking metal surface
  • broaching to create holes, teeth and keyways.

We specialise in machining stainless steel components for a number of applications and industries. We provide a full design service and handle all elements of machining plus extensive quality control testing and inspection. Whatever your stainless steel needs, we can handle them to your exact specifications and to meet the highest standards. Read Less
