Where is the stainless steel maintenance training?

Beijing has stainless steel maintenance training.

Stainless steel is a metal material, which consists of stainless steel and acid-resistant steel. Stainless steel is the abbreviation of stainless and acid-resistant steel, and it is also a kind of steel. Because of the difference between stainless steel and acid-resistant steel, their corrosion resistance is also different. Generally speaking, stainless steel is not corrosion-resistant, while acid-resistant steel is generally stainless steel with good mechanical properties and weldability.

Stainless steel is a kind of high-grade alloy steel, its main alloying element is chromium, and its carbon content is low. Stainless steel has strong luster, cold and hard feel, strong toughness and corrosion resistance, high rust resistance and good processability, and is often used in light industry, heavy industry and architectural decoration industry. Many kinds of stainless steel are usually magnetic, for example, austenitic stainless steel is usually not magnetic.

The types of stainless steel include martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel, precipitation hardening stainless steel, stainless steel plate and steel strip for pressure equipment, etc.

Martensite steel: because of its high carbon content, it has high strength, hardness and wear resistance, but its corrosion resistance is slightly poor. Ferrite steel: Because of its high chromium content, it has good corrosion resistance and oxidation resistance, but its mechanical properties and technological properties are poor.

Austenitic steel: This steel has good plasticity, toughness, weldability, corrosion resistance, no magnetism or weak magnetism.
