Advantages of Machining Stainless Steel Parts

Stainless steel is a family of iron-based alloys that contain a minimum of roughly 11 percent chromium, an element that prevents rust and withstands extreme temperatures. This material also has a long cycle life and is 100 percent recyclable, making it environmentally friendly.

There are over 150 grades of stainless steel, a handful of which are used in everyday applications. Specific performance characteristics will vary by grade, but here are common traits.


  • Corrosion resistance
  • Strength
  • Easy to clean
  • High-temperature resistance
  • Simple to sterilize
  • Low-temperature resistance
  • Aesthetic appeal
  • Improved weldability
  • Low weight
  • Strong formability
  • Magnetism resistance, in some cases

Industries for Stainless Steel Parts

Stainless steel’s valued performance characteristics and easy-to-manufacture traits make it ideal for a range of applications. It’s made into automobile exhaust systems, grills, and trim as well as surgical instruments and medical-implantable devices. Crude oil and natural gas drilling operators value stainless steel’s resistance to extreme hot and cold temperatures, corrosive environments, and acidic conditions. Kitchen applications prize the material’s rust resistance, cleanliness, and lack of influence on food taste. Here are some industries that utilize stainless steel.

  • Automotive
  • Architectural
  • Construction
  • Electronics
  • Renewable energy
  • Mining
  • Furniture

Stainless Steel Alloys

While Moon Tool & Die can machine, weld, and assemble any material, we work most often with 300, 400, and 17-4 series stainless steels. Each series has unique performance characteristics that are worth scrutinizing when choosing stainless steel for a project. 


303 Stainless Steel

A chromium-nickel alloy modified by the addition of selenium, sulfur, and phosphorus to improve machinability and non-seizing properties. It’s easily processed and has good corrosion resistance. Typical uses are components that require machining, grinding, or polishing, which include shafts, gears, valves, bolts, screws.


304 Stainless Steel

A very low carbon, magnetism-resistant chromium-nickel alloy. It has high malleability, good corrosion resistance, and superior resilience to intergranular corrosion following welding or stress relieving. Common uses include food-processing equipment, screws, machinery parts, car headers, and architectural accents.


316 Stainless Steel

A magnetism-resistant, chrome-nickel alloy with superior corrosion resistance. It withstands exposure to harsh chemicals and marine environments. Usual applications for this material are food-preparation machinery, laboratory equipment, coastal paneling, marine parts, chemical containers, heat exchangers, fasteners, and springs. 


410 Stainless Steel

Has 11-1/2 percent chromium and offers exceptional wear and corrosion resistance. Common applications include dental and surgical instruments, pipelines, valves, nozzles, and automotive parts.


420 Stainless Steel

A material that offers increased hardness, improved strength, and better wear resistance. It contains a minimum of 12 percent chromium, which results in strong corrosion-resistant properties. This material is made into cutlery, surgical instruments, needle valves, and shear blades.


17-4PH Stainless Steel

Has high levels of strength, hardness, and corrosion resistance. Being martensitic, it’s magnetic. It’s commonly used to manufacture pump shafts, oilfield components, mechanical seals, and aerospace parts. 


17-4H900 Stainless Steel 

A material that offers a good balance of corrosion resistance and strength. It’s magnetic and can be precipitation-hardened with heat treatment. Some applications include aircraft parts, nuclear equipment, food processing machines, and paper mills. 


17-4H1150 Stainless Steel

A precipitation-hardened, chromium-copper alloy that exhibits high strength and a moderate level of corrosion resistance. It’s magnetic and heat-treated to add strength. Typical uses are valve components, pump shafts, aerospace parts, turbine blades, nuclear waste casks, offshore applications, food-processing tools, and pulp-and-paper industry equipment. 


In addition to the list above, Moon Tool & Die can also machine, weld, and assemble the following grades of stainless steel:

  • 1018
  • 1045
  • 12L14
  • 4130
  • 4140
  • A36
