What is 5620 Alloy Steel? Understanding Your Material Options
When you source 5620 alloy steel machining, you are usually looking at two entirely different metals based on the prefix. A wrong material callout wastes time and ruins production runs. We clarify these specifications immediately to ensure your 5620 alloy steel machined parts perform exactly as engineered.
SAE 5620 & 86L20 Low-Carbon Steel Alloys
The SAE 5620 designation closely mirrors 86L20 low alloy materials. These are low carbon steel alloys engineered specifically for heavy-duty wear applications. We utilize these carburizing grades when you need parts that absorb shock without fracturing.
- Tough Core: Offers high ductility and impact resistance.
- Surface Hardness: Responds perfectly to carburizing for a wear-resistant case.
- Machinability: Behaves as a true free-machining steel, which lowers tool wear and cuts your production costs.
AMS 5620 (Alloy 420F Stainless Steel)
If your print specifies AMS5620, you actually need Alloy 420F stainless steel. This is a medium carbon, hardenable free machining grade. We machine this specific alloy when your components demand high hardness combined with reliable corrosion resistant properties. It is our standard choice for high-volume runs requiring both edge retention and fast cycle times.

Frequently Asked Questions (FAQs)
What is the difference between 420 and 420F (AMS 5620) stainless steel?
The core difference comes down to machinability. Standard 420 is a medium carbon, hardenable steel that offers good corrosion resistance. However, Alloy 420F (AMS 5620) has added elements like sulfur to make it a true free-machining steel turning grade. These additions allow metal chips to break away cleanly during the cutting process. As a result, we achieve faster cycle times, reduced tool wear, and exceptional surface finishes for your 5620 alloy steel machined parts.
Is SAE 5620 suitable for high-pressure applications?
Yes, it performs very well in these environments. SAE 5620 is a low carbon steel alloy specifically designed for carburizing. Once heat-treated, it develops a hard, wear-resistant outer case while maintaining a tough, ductile core. This makes it a reliable choice for hydraulic fittings, valves, and high-stress mechanical components. If your project requires testing out different carburizing alloy steel grades for pressure applications, it offers performance very similar to what you would expect from 8620 alloy steel machined parts.
What are the maximum dimensions Vastmaterial can machine for 5620 parts?
Our AMS 5620 machining services are scaled to handle everything from micro-components to large, heavy-duty parts. For high-volume alloy steel manufacturing, our current capabilities are:
- Precision Swiss Machining: Perfect for intricate, small-diameter components up to 1.25 inches (32mm) in diameter.
