Acid resistant steel for Micro-carbon ferrochrome applications

The addition of chromium to steel can significantly improve the oxidation resistance and corrosion resistance of steel. Chromium is found in many steels with special physical and chemical properties. Micro-carbon ferrochrome is used in the production of stainless steel, acid-resistant steel, heat-resistant steel and electric heating alloys.

What is acid-resistant steel:

  • Acid-resistant steel has good mechanical properties, good hot and cold processing properties, weldability and good corrosion resistance.
  • Chromium is the main alloy element of acid-resistant steel, followed by nickel, molybdenum, titanium, niobium, copper, etc.
    It is mainly used in the production of parts that work in environments with strong corrosive media.

Acid-resistant steel can be divided into three categories according to its arrangement:

(1) Austenitic stainless steel has a certain strength and good toughness, and has good corrosion-resistant properties;

(2) Ferritic stainless steel has excellent oxidation resistance, but relatively poor corrosion resistance.

(3) Martensitic stainless steel, although its corrosion resistance is poor, has good strength properties and can produce components with low corrosion resistance and high mechanical performance requirements.

It can be divided into two major groups according to its use:

  • the first group is stainless steel, that is, steel that can resist corrosion in the air, mainly used in making turbine blade measuring tools, medical equipment, scissors, cutting tools and tableware, etc.;
  • The second category is acid-resistant steel, which can resist the corrosion of various corrosive media. The first group is used to make acid-resistant steel, which can resist the corrosive action of various corrosive media.
