Custom Stainless steel parts

Stainless steel is a fully recyclable alloy composed of iron, carbon and between 11-18% chromium. This hardens and toughens the steel, increasing its corrosion resistance at high temperatures and preventing rust. Stainless steel is very strong, resistant to corrosion, easy to clean and sterilize—especially useful for medical equipment—resistant to extreme temperatures and great for welding. Our CNC services enable you to create custom stainless steel parts for many applications across industries such as energy, medical technology, agricultural, industrial automation, machinery, robotics and construction. With us, your parts are machined directly from the information of a CAD file and a technical drawing, both of which can be uploaded onto our platform.

Frequently asked questions

How much does CNC stainless steel cost?

The cost of CNC machining stainless steel depends on the complexity and size of the part and the type of stainless steel that is used. These variables will affect the type of machine that is required, the time it takes to produce the part, and the cost of the raw material.

We use machine learning algorithms to calculate the exact cost of any machinable part directly from a CAD file, based on millions of CNC machining orders we’ve previously processed. Simply upload a CAD file to generate a quote: get an instant CNC machining quote.

What is stainless steel machining?

Stainless steel machining is a manufacturing process that involves cutting a piece of raw stainless steel until a final desired shape or object remains. A CNC machine cuts parts out of raw pieces of Stainless steel with a milling tool with high accuracy and precision, allowing for complex geometries and complicated custom parts.
