Stainless steel sheet surface finish characteristics

Surface finishCharacteristics and application
2BThe surface brightness and flatness of no2B is better than no2D. then through a special surface treatment to improve its mechanical properties,No2B could nearly satisfy comprehensive uses.
No.1Polished with abrasive belt of grit#100-#200, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc.
No.4Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc.
HLPolished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators, door of building, frontal plate etc.
BACold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus, ornament etc.
8KThe product have excellent brightness and prefer reflexivity can to be the mirror.

Characteristics of 443 stainless steel

  • 1, 443 stainless steel chemical composition and mechanical properties of indicators: carbon (C) = 0.01%, chromium (Cr) = 21.0%, titanium (Ti) = 0.3%, the yield strength of sigma 0.2 = 305 mpa, sigma b = 483 mpa tensile strength, elongation El = 31%.
  • 2, 443 stainless steel material properties: index of resistance to pitting corrosion of 443 stainless steel substrates is 300 mv, 304 stainless steel and its high thermal stability, good tensile properties.
  • 3, excellent material properties than ordinary ferritic stainless steel, 443 stainless steel by adding Cr, lower C, Ti improve corrosion resistance. Pitting corrosion resistance increase, increase the content of Cr improve corrosion resistance, stainless steel substrates increase Ti improve its pitting corrosion resistance. The increase of the content of Cr can improve the electrode potential of stainless steel matrix, and at the same time Ti in priority and C to form stable compounds in stainless steel, C and Cr in stainless steel compound, suppresses the poor Cr point, improve the pitting corrosion resistance. Heat to improve service life: Ti element priority C compound formation, restrain the enrichment of stainless steel under the condition of heat C to grain boundary, increases the service life of the stainless steel heat, at the same time improve the stainless steel intergranular corrosion resistant performance, improve the thermal stability of the stainless steel.
