00Cr24Ni22Mo7Mn3CuN...
Stainless SteelsHuaNickel 00Cr24Ni22Mo7Mn3CuN steel series is based on the aforementioned 00Cr20Ni18Mo6CuN steel to increase chromium. A 7Mo type super austenitic stainless steel developed by nickel and molybdenum. The PRE value (Pitting Resistance Equivalent Value) of this steel is as high as 55. The nitrogen content in steel can reach about 0.5%, which is almost the highest amount of dissolved nitrogen at atmospheric pressure for stainless steel with high chromium (about 24%) and low manganese (about 3%). This steel has excellent resistance to various types of corrosion, and can replace iron-nickel-based or even nickel-based corrosion-resistant alloys in many media, thus filling the gap between stainless steel and high-nickel corrosion-resistant alloys without high pitting resistance and high crevice corrosion resistance stainless steel.

00Cr25Ni4Mo4...
Ferritic stainless steelHuaNickel 00Cr25Ni4Mo4(Ti,Nb) enterprise trade number is MONIT, referred to as 25-4-4, is a kind of high chromium, molybdenum super ferritic stainless steel containing stabilized elements. The steel was developed in 1974 by Nyby in Sweden. Nickel is added to reduce the brittle transition temperature of the steel; Due to the high C+N content (≤0.04%) in the initial stage, the steel has a high tendency to intergranular corrosion, and the presence of stabilizing elements is to prevent intergranular corrosion during use after welding or high temperature cooling. Due to the high chromium and molybdenum content of this steel, the local corrosion resistance caused by chloride is excellent, the strength of this steel is high, and it has acceptable plasticity, toughness and welding properties under thin cross-sectional size conditions (such as ≤3~5mm), and can replace high-nickel austenitic stainless steel and high-nickel corrosion-resistant alloy under some medium conditions.
