Product details:
Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial,architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

The 18% minimum chromium content provides corrosion and oxidation resistance. The alloy's metallurgical characteristics are established primarily by the nickel content (8% mm.), which also extends resistance to corrosion caused by reducing chemicals. Carbon, a necessity of mixed benefit, is held at a level (0.08% max.) that is satisfactory for most service applications.

Surface/Finish--stainless steel coil
We have below finishes for you. Please choose the available surface.
Surface |
Definition |
NO.1 |
No. 1 finish has rough, dull, and non-uniform appearance. There may be shiny spots were surface imperfections were removed by grinding. It is generally used in industrial applications, such as equipment for elevated temperature service. |
2B |
No. 2B Finish is a bright cold rolled finish commonly produced in the same manner as No. 2D, except that the final light cold rolling pass is done using polished rolls. This produces a more reflective finish that resembles a cloudy mirror. |
NO.4 |
No. 4 Finish is characterized by short, parallel polishing lines, which extend uniformly along the length of the coil. It is obtained by mechanically polishing a No. 3 finish with gradually finer abrasives. |
HL |
Hairline finish is long line finish, which in a way resembles combed hair. |
BA |
Ba finish is produced by heat-treating (annealing) in a controlled atmosphere furnace. It has a mirror like appearance but may have some cloudiness and other imperfections. A finish that is designated “BA” has only been bright annealed. |
Mirror/(No.8) |
In comparison to a No. 7 finish, the grit lines are much less visible, but they can be seen if the finish is examined closely. The resulting finish is mirror-like but not a perfect mirror. |
Mill Test Certificate-- stainless steel coil
The basic resistance of stainless steel occurs because of its ability to form a protective coating on the metal surface. This coating is a "passive" film which resists further "oxidation" or rusting. The formation of this film is instantaneous in an oxidizing atmosphere such as air, water, or other fluids that contain oxygen. Once the layer has formed, we say that the metal has become "passivated" and the oxidation or "rusting" rate will slow down to less than 0.002" per year (0,05 mm. per year).
Stainless gets its non corrosive properties from the chromium in the alloy. It's created when oxygen combines with the chrome in the stainless to form chrome oxide which is more commonly called "ceramic". This protective oxide or ceramic coating is common to most corrosion resistant materials. The chromium atoms combines with oxygen and forms a passive surface film over the base steel very much like the paint protects your car. Once this layer is removed the base metal is exposed to the moisture in the atmosphere and rust forms. Chlorine in any form combines with the chromium and removes this protective layer and exposes the base metal and rust will occur. The stainless steel pitting resistance equivalent is below:
Never use any chemicals that contain chlorine near any stainless. This includes any cleaners, acids to clean quarry tile or brick, and some detergents. Even the vapors can attack stainless steel. The only inorganic acid that is friendly to stainless is nitric and it is used to remove any iron particles left on the surface from manufacturing or machining. Never use steel wool to clean stainless. Particles of the steel wool will get trapped in the grain of the stainless and these steel particles will rust. Halogen salts, especially chlorides easily penetrate this passive film and will allow corrosive attack to occur. The halogens are easy to recognize because they end in the letters "ine". Listed in order of their activity they are: fluorine, chlorine, bromine, iodine, astatine.
