Stainless steel matrix classification:

  1. Ferritic stainless steel. Containing 12% to 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its resistance to chloride stress corrosion is better than other types of stainless steel.
  2. Austenitic stainless steel. Containing more than 18% chromium, it also contains about 8% nickel and a small amount of elements such as molybdenum, titanium and nitrogen. Good overall performance, resistant to a variety of media corrosion.
  3. Austenitic – ferritic duplex stainless steel. It combines the advantages of austenitic and ferritic stainless steels and has superplasticity.
  4. Martensitic stainless steel. High strength, but poor plasticity and weldability.

There are many types of stainless steel. Austenitic stainless steel (1Cr18Ni9Ti) is commonly used for sheet metal processing. JIS (SUS)

Aluminum alloy elemental content classification:

  • 1000 series, 2000 series, 3000 series, 4000 series, 5000 series, 6000 series, 7000 series, 8000 series.

Aluminum is a silver-white light metal with good thermal conductivity, electrical conductivity and ductility. Pure aluminum has a very low strength and cannot be used as a structural material. Aluminum sheet is generally used for sheet metal processing.

Commonly used are 2000 series, 3000 series and 5000 series:

  • The 2000 series is a copper-aluminum alloy characterized by high hardness, also known as hard aluminum; it can be used as a variety of medium-strength parts and components.
  • 3000 series is a kind of manganese aluminum alloy, which has good anti-rust performance, so it is also called rust-proof aluminum.
  • 5000 series is a kind of magnesium alloy. Its main features are low density, high tensile strength and high elongation. The weight is lower than other series under the same area.
