420 Stainless Steel Machining

In need of 420 stainless steel CNC machined parts? Let the experts at Continental Manufacturing handle your 420 stainless steel CNC machining! Since 1954, we have manufactured and machined a variety of stainless steel grades including the 400 series like 420. This particular grade of stainless steel is used for parts made on automatic screw machines, such as valve trim, pump shafts, needle valves, ball check valves, gears, cams, pivots, etc. 420 Stainless is used in applications that require high hardness and good corrosion resistance. 

420 Stainless Steel Characteristics

Alloy 420 is martensitic stainless steel that is similar to type 410 except with higher strength and hardness properties. Type 420 stainless steel is not commonly welded due to its high hardening properties but it can be done. Its corrosion resistance is lower than other austenitic grades, but best when the metal is hardened or polished. Due to Alloy 420’s high level of corrosion and hardness, it is commonly used for applications such as:

  • Medical / Surgical
  • Surgical Equipment
  • Cutlery
  • Tools & Blades

We provide our customers with stainless steel machined parts that contain excellent features such as resistance to corrosion, scale, acids, cryogenic temperatures, and impact which makes it an incredibly tough and versatile option. All of our stainless steel products are guaranteed to be 100% recyclable and eco-friendly. Continental Manufacturing is located in Dallas, Texas, and proudly serves and delivers high-quality products nationwide.
