We offer a complete stainless steel CNC machining service and can produce complex stainless steel parts with 11 different types of stainless steel.

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, agriculture, industrial automation, machinery, robotics and construction.
