Stainless steel can be classified into two main categories based on its chemical composition: chromium (Cr) stainless steel and chromium-nickel (Cr-Ni) stainless steel. The corrosion resistance of stainless steel is primarily influenced by the carbon (C) content and the precipitation of carbides. Th

Martensitic stainless steel includes martensitic and precipitation hardening types. In engineering applications, the focus is primarily on mechanical properties. Although these steels have good corrosion resistance in atmospheric and mild corrosive environments (such as water and certain organic med

Chromium is the primary alloying element in this type of steel, with a chromium content typically ranging from 13% to 30%. It possesses excellent resistance to oxidation and corrosion in various media, as well as the ability to withstand air oxidation at high temperatures, making it suitable for hea

Austenitic stainless steel can be divided into four groups: Cr-Ni series; Cr-Ni-Mo, Cr-Ni-Cu, or Cr-Ni-Mo-Cu series; Cr-Mn-N series; and Cr-Ni-Mn-N series. The Cr-Ni series is represented by "18-8". The Cr-Ni-Mo, Cr-Ni-Cu, and Cr-Ni-Mo-Cu series add 2%-3% molybdenum and copper (or both) to improve r

What are the main applications of precision mechanical processing?Precision mechanical processing is typically used in industries such as automotive manufacturing for mass production, aerospace for parts production, shipbuilding for component manufacturing, as well as testing of new models and engin

Austenitic-ferritic duplex stainless steel is a type of steel that typically contains 5%-40% ferrite to improve the alloy's weldability, increase strength, and enhance stress corrosion resistance. For example, the high carbon and high chromium alloy steel with 28% chromium, 10% nickel, and 0.30% car
