Stainless Steel 416 Properties

Ferrobend comes to materials that offer both strength and versatility, few options can compete with stainless steel 416. Widely used across industries like aerospace, automotive, manufacturing, and more, 416 stainless steel is known for its exceptional corrosion resistance and excellent machinability. Ferrobend, a leading manufacturer of high-quality stainless steel products, provides this material with unmatched precision and reliability. In this article, we’ll dive deep into the features, benefits, applications, and why Ferrobend’s Stainless Steel 416 is the best choice for your next project.

Stainless steel 416 is a martensitic grade of stainless steel that contains a higher amount of sulfur, which enhances its machinability. This alloy primarily consists of iron, chromium (12–14%), and a small amount of sulfur (0.15–0.40%), making it ideal for applications that demand high levels of hardness, toughness, and corrosion resistance. Stainless Steel 416 is often considered a modified version of 410 stainless steel. The addition of sulfur improves the material’s machinability, making it easier to shape and cut without compromising its corrosion resistance. Unlike austenitic stainless steels like 304 or 316, 416 stainless steel is magnetic, which adds to its appeal in various applications.

Ferrobend uses state-of-the-art technology and industry-best practices to produce stainless steel 416. The company is committed to quality control at every step of the manufacturing process, ensuring that each product meets the highest standards for consistency and performance.

Heat Resistance:

  • Good oxidation resistance at temperatures up to 1700oF (927 oC)
  • Continuous use at temperatures above 1400oF (760oC) is not usually recommended due to carbide precipitation which can lead to irregular scaling
  • Does not have a low carbon content so it is also vulnerable to sensitization

Welding Characteristics:

  • Not generally recommended, but may be welded with some difficulty
  • May be welded with Alloy 310 electrodes
  • Should be annealed after welding to re-dissolve precipitated carbides

Machinability:

  • High machining rates can be obtained in the annealed condition with hardness in the range of 200 to 240 Brinell
  • Will work harden; therefore, it should be machined at reduced surface feet per minute and heavier feeds to prevent glazing at the tool interface.

Applications:

  • Nuts and bolts
  • Aircraft fittings
  • Gears
  • Screws
  • Shafts
  • Electrical switchgear components
  • Bushings
