CNC Stainless Steel
CNC Stainless Steel is a kind of high strength, corrosion resistance, high temperature resistant alloy material, mainly composed of iron (Fe), chromium (Cr), nickel (Ni), carbon (C) and other elements. It is widely used in CNC machining to manufacture precision parts, structural parts, medical devices, automotive parts, etc., and is favored for its excellent mechanical properties, durability, and surface treatment adaptability.

Why Stainless Steel Make Sense for CNC Machining
Excellent corrosion resistance
Stainless steels such as 304 and 316 contain chromium and form a protective oxide layer, making them suitable for wet, chemical, and food-grade environments.
High strength and durability
Stainless steel provides strong mechanical performance and long service life for structural parts, fasteners, shafts, and housings.
Good heat resistance
Many stainless steel grades maintain strength and oxidation resistance at elevated temperatures, suitable for heat-exposed components.
Clean and hygienic surface
The smooth, non-porous surface is easy to clean and suitable for medical, food processing, and laboratory equipment.

Finishes That Make Sense For Stainless Steel
Passivation
Removes free iron and enhances the natural chromium oxide layer to improve stainless steel corrosion resistance.
Electropolishing
Smooths and brightens the surface through electrochemical removal, improving cleanliness and corrosion resistance.
Bead Blasting
Creates a uniform matte finish and reduces visible machining marks on stainless steel parts.
Brushing
Creates a directional satin grain for decorative panels, housings, handles, and visible components.

Lightweight Metal
CNC Aluminum Alloys
CNC-machined Aluminum Alloys are widely used across various industries due to their lightweight, high strength, corrosion resistance, and excellent machinability. These alloys offer superior mechanical properties while maintaining cost-effectiveness, making them an ideal choice for aerospace, automotive, electronics, and industrial applications.
Higher Strength
CNC Steel Alloys
CNC Steel Alloys refers to the steel alloy used for CNC processing, that is, on the basis of carbon steel to add other alloying elements (such as chromium Cr, nickel Ni, molybdenum Mo, vanadium V, manganese Mn, etc.) to improve its strength, hardness, wear resistance and corrosion resistance. Steel alloys are widely used in aerospace, automotive manufacturing, industrial equipment, medical devices and tool manufacturing.
Premium Strength-to-Weight
CNC Titanium Alloys
Titanium Alloys are a kind of high strength, low density, corrosion resistance, high temperature resistance of metal materials, widely used in aerospace, medical, automotive, Marine engineering, military and other fields. Due to the high strength-to-weight ratio and excellent corrosion resistance of titanium alloys, it is difficult to process them, so special tools and processing strategies are required for CNC machining.
