430 Stainless Steel
Type 430 is ductile, has good forming characteristic and is readily fabricated by such operations as bending, pressing, drawing and heading. Its tendency to work harden is much less than that of the nickel-bearing 300 series stainless steel. Type 430 does not have as good corrosion resisting properties as the chromium nickel steels. However, it is suitable for interior architectural and decorative household appliances trim as well as automotive body molding. Cold rolled Type 430 has an attractive bright finish which can be maintained with reasonable care and periodic cleaning. Type 430 is by far the most popular of all straight chromium stainless steels. It is the general purpose alloy of the ferritic class. This type contains approximately 17 percent chromium and is often referred as 17 chrome stainless. The higher chromium content imparts improved resistance of Type 430 is slightly less than carbon steel, but its thermal conductivity is one half that of carbon steel. Chromium stainless steel is magnetic.

Cold forming with low amount of deformation is easily feasible above room temperature. Sharp chamfers parallel to the direction of rolling have to be avoided. Sheets with greater thicknesses and/or higher amount of deformation should be preheated up to 200 - 400 °C. If applicable, a hot forming at 700 - 900 °C can be necessary. The corrosion resistance is affected by annealing colors, which occur after hot forming or welding, or scalings. These have to be removed by pickling (pickling solution), grinding or sand blasting. It is only allowed to use iron-free tools for these workings. Machining does not differ from machining of non-alloy carbon steels with comparable or corresponding strength.

Finish Definition:
| Surface Finish | Characteristics and Application |
| No.1 | Hot-rolled surface,annealed and pickled, can be used for cold rolling material,industrial tanks and chemical devices. |
| No.2D | Cold-rolled, annealed and pickled without skinpass. the dull products can be used as automobile parts,building materials and pipes |
| No.2B | The surface brightness and flatness of No.2B is better than No.2D. Then through a special surface treatment to improve its mechanical properties. No.2B could nearly satisfy comprehensive uses. |
| No.3 | Polished with abrasive belt of grit #100-#120, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building.electrical applicances and kitchen utensils etc. |
| No.4 | Polished with abrasive belt of grit #150-#180, have better brightness with discontinuous coarse stria,but thinner than No.3, are used as bathtub building's inner and external ornaments electrical appliances,kitchen utensiles and food processing equipment etc . |
| HL | Polished with abrasive belt of grit#150-#320 on the No.4 finish and has continuous streaks, mainly used as building's ornaments,elevators,door of building,frontal plate etc. |
| BA | Cold rolled,brigth annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror,used for electrical applicances,mirrowr,kitchen apparatus,ornament materials etc. |
