Other common names: Carpenter 20, 20Cb-3®, Incoloy® alloy 20

Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid. This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Although originally designed for use in sulfuric acid related industries, Alloy 20 is now a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries. In addition, this superalloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping.

There has long been a debate on whether Carpenter 20 is a stainless steel or a nickel alloy because the nickel content is right on the border of defining it as one way or the other. So, depending on who you talk to this alloy may be referred to as alloy 20 Stainless Steel or as a nickel alloy. Either way it is still great for corrosion resistance.

  Nickel 200 (UNS N02200/ w.r.2.4060 and 2.4066)

  Nickel 200 this alloy has the following characteristics:

  It is commercial pure nickel (99.6%).It has good mechanical properties and excellent resistance in many corrosive environments.Other useful features of the alloy include its magnetic properties, magnetostrictive properties, high thermal and electrical conductivity, low gas content and low evaporation pressure.Corrosion resistance makes it particularly useful in applications where purity is required for products such as food, synthetic fibres and caustic soda.It is also widely used in structural applications where corrosion resistance is the main consideration.Other USES include chemical transfer barrels, electrical and electronic components, aerospace and missile components.

  Metallographic structure of nickel 200:

  Nickel 200 is a solid alloy with a face-centered cubic structure.

  High temperature performance:

  Nickel 200 is generally restricted to use at less than 600°F (315°C).The graphitization of nickel 200 products will occur at high temperature, which will seriously degrade the performance of the products.

  Available products and standards:

  Landong can supply N6 nickel strip, N6 nickel sheet, N6 nickel foil, N6 nickel wire, N6 nickel tube, N6 nickel plate, N6 nickel rod, etc.Welcome to inquir

  The corrosion resistance of N4/N6 pure nickel, especially alkali corrosion resistance, is relatively stable in both high temperature and molten alkali, so it is mainly used in alkali making industry.At room temperature, nickel is extremely stable in seawater and salt solutions and in organic media such as fatty acids, phenols, alcohols, etc.It is not resistant to inorganic acids and is unstable in acetic acid and formic acid.
