Grade 430 contains 16Cr-0.05C. It is representative of Ferritic Stainless Steel. It has low thermal expansion coefficient,excellent oxidation resistance.
430 stainless steel has the following states, the state is not the same, dirty and corrosion resistance is not the same.
1D- The surface has a discontinuous granular shape, also known as fog surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D- A slightly glossy silver white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B- silvery white and better gloss and flatness than 2D surfaces. Processing technology: hot rolling + annealed shot peening pickling + cold rolling + annealed pickling + tempered rolling.
BA- Excellent surface gloss, high reflectivity, like a mirror surface. Processing technology: hot rolling + annealed shot peening pickling + cold rolling + annealed pickling + surface polishing + tempering rolling.
No.3- Good gloss, coarse grain surface. Processing technology: 2D products or 2B are polished and rolled with 100~120 grinding materials (JIS R6002).
No.4- Good gloss and fine lines on the surface. Processing technology: 2D products or 2B are polished and rolled with 150~180 grinding materials (JIS R6002).
HL- silvery gray with streaked hair. Processing technology: 2D products or 2B products with appropriate particle size abrasive materials to polish the surface is continuous grinding grain.
MIRROR- In a mirror state. Processing technology: 2D products or 2B products with appropriate particle size grinding materials for grinding and polishing to mirror effect.
It is widely used in Heat resistant products, Burners, Home appliances, Computer components(HDD), Flatware, Interior and exterior materials for architecture, Gas range stoves, Washing machine drums etc.
