CNC machining stainless steel material
Steel is an iron and carbon alloy which include at least 10.5% chromium, less than 1.2% carbon, and other alloying elements are known as stainless steels. Other elements, such as nickel, titanium, molybdenum, manganese, niobium, etc., can be added to stainless steel to greatly improve its mechanical and corrosion resistance.
Application
Stainless steel can be machined to produce high performance parts used in industries like food and beverage, vehicle, energy and firearms and automobile etc.
Advantages
excellent corrosin resistance
excellent machinical properties
easily welded

Stainless steel surface finishes
Exzellenc provides different types of finishes for stainless steel to improve the part performance and aesthetic look.
#4 finish:With this finish, you can hide scuffs, fingerprints, scratches, and other surface flaws while still maintaining a great bright, brushed look.
2B finish:The most typical mill finish for light gauge stainless steel sheet is a brilliant, cold-rolled finish. It looks like a very foggy mirror with some reflection. It is produced by passing the sheet through polished rolls.
Powder coating:An exceptional and durable surface finish is made by powder coating. Many different substances can cause corrosion in stainless steel, while others, such chlorides, still present a problem. In these circumstances, powder coating can be employed to enhance the object's anti-corrosion capabilities.
