Stainless steel 443 material composition:

Carbon [C] = 0.008%, chromium [Cr] = 21.0%, antimony [Ti] = 0.3%, yield strength of σ0.2 = 305Mpa, tensile strength of σb = 483Mpa, elongation El = 31%.

Stainless steel 443 material properties:

443 stainless steel matrix pore corrosion resistance index of 300mv, and 304 stainless steel is comparable to the thermal stability, good tensile properties.

Material properties of ordinary ferritic stainless steel excellent:

443 stainless steel through the increase of Cr, reduce C, add Ti to improve corrosion resistance. Improvement of pitting resistance: increase the content of Cr to improve the corrosion resistance of the stainless steel matrix, increase Ti to improve its pitting resistance. the increase in Cr content, improve the electrode potential of the stainless steel matrix, at the same time Ti in the stainless steel preferentially with C to form stable compounds, inhibit the stainless steel C and Cr synthesis, inhibit the emergence of Cr-poor points, improve its pitting resistance. Improvement of thermal service life: Ti element gives priority to the formation of C compounds, inhibits the enrichment of C to grain boundaries in stainless steel under heat conditions, improves the thermal service life of stainless steel, and at the same time, improves the intergranular corrosion resistance of stainless steel, and improves the thermal stability of stainless steel.
