1Cr19Ni11Nb stainless steel

1Cr19Ni11Nb is a Nb-containing austenitic stainless steel.

1Cr19Ni11Nb introduction:
1Cr19Ni11Nb has good intergranular corrosion resistance, and has good corrosion resistance in alkali, seawater and various acid solutions. Due to its good heat resistance and oxidation resistance, it can withstand small loads at temperatures below 850 degrees.
