13-8 Stainless Steel

Great Lakes Forge offers the industry's best lead times for 13-8 stainless steel forgings. We can create custom forgings up to 12' in length, from 2.5" to 24" in diameter/thickness, and up to 6,000 lbs. We can create a variety of custom forges including:

With the industry's fastest turnaround times, our forging services are ideal for high or low volume production, as well as prototyping.

Our in-house machine shop, testing capabilities, and quality-controlled heat-treating processes guarantee the consistency, quality, and dimensional accuracy of forged parts. We also offer numerous milling and rough turning capabilities to deliver products that are close to intended size and shape at reasonable cost.

In addition to 13-8 stainless steel Great Lakes Forge has the capabilities to forge over 200 different materials. If your project requires a specific grade of steel, please don't hesitate to contact us. The material you need may be in our inventory, and if it isn't, close relationships with our material providers enable us to procure the material you need quickly and cost-effectively.

13-8 Stainless Steel Properties

13-8 stainless steel is a martensitic precipitation/age-hardening material with many quality characteristics including:

  • High Strength
  • High Hardness
  • High Fatigue Strength
  • Good Galling & Stress Corrosion Resistance
  • Exceptional Oxidation Resistance (up to 1100°F/593°C)
  • Excellent Corrosion Resistance (comparable to chromium nickel grades)

13-8 stainless steel's closely controlled chemical composition and microstructure provide a higher level of useful mechanical properties under severe environmental conditions than other ferrous metals.

13-8 Stainless Steel Hardness

Tempered 13-8 stainless steel can achieve Brinell scale hardness of up to 430, and Rockwell hardness of up to C45.

13-8 Stainless Steel Heat Treatment

13-8 stainless steel can be hardened through solution heat treatment at temperatures from 950°F/510°C to 1150°F/621°C for four hours. Air cooling to below 60°F/16°C to allow for complete martensite transformation.

13-8 Stainless Steel Machinability

Cutting speed of 13-8 stainless steel averages 80 ft/min, similar to 17-4 stainless. Machinability of age-hardened 13-8 stainless steel improves in proportion to increases in hardening temperature.
