CNC Machining in Stainless Steel
High tensile strength, corrosion and temperature resistant. Stainless steel alloys have high strength, ductility, wear and corrosion resistance. They can be easily welded, machined and polished.

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.
BZ Metal Products' CNC machining 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 used. These variables affect the type of machine required, production time, and raw material cost.
BZ Metal Products uses advanced algorithms to calculate the exact cost directly from your CAD file, based on thousands of previous CNC machining orders we've processed. Simply upload your CAD file to receive an instant 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.
