Stainless Steel: A versatile raw material

It was discovered before the turn of the century that the corrosion of A234 WPB steel could be solved by adding nickel and chromium. But steels rich in these elements still leave much to be desired. Significant changes occurred in 1912 in Germany. For the first time, thanks to the combination of nickel and chromium with precise dosing of heat treatment, it was possible to achieve excellent corrosion resistance by 316l stainless steel fasteners manufacturers in india while maintaining good mechanical properties. Characteristics and Advantages of the Material

Stainless steelis a Cr-Ni alloy steel, resistant to austenitic acid 18/10, thanks to its low hydrogen content it has very good anti-corrosion properties. For higher temperatures, titanium stabilized A420 WPL6 steel must be used. Steel is resistant to water, steam, moisture and food acid, as well as weak organic and inorganic acids, and is very diverse in its business opportunities: the food industry, beverage production, the pharmaceutical and cosmetic industries.

The advantages ofstainless steel are:

  • Corrosion resistant
  • Resistant to temperature changes
  • Antistatic
  • Viscous
  • Hygienic
  • Maintenance free
  • Durable

Stainless steel after

  1. a) Intercrystalline corrosion 44 When chromium the carbide is critically released on the grain boundary. The environment then loses chromium, which reduces the passivation effect. Alloy steel sheet 1.4541, 1.4571 and 1.4435 is considered resistant to crystalline corrosion.
  2. b) Pitting corrosion

In the case of this corrosion, the carbon steel plate is only broken at certain points. The result is a hole or holes formed on the outside by Super duplex fasteners manufacturer in India. Pitting corrosion is mainly caused by halogen ions, especially chloride ions. It can be fortified topically with water and sewage and is often associated with the presence of chlorine and chloride ions.

  1. c) Galvanic corrosion

This corrosion is very frequent and is created when a c45 metal plate of different potential comes into contact in the presence of an electrolyte. In this case, the less noble metal is attacked by the electrolyte and dissolves. The amount of corrosion is proportional to the amount of electricity that circulates in this galvanic element. This type of corrosion is very common with Inconel 625 Hex Bolts manufacturer in India. One of the best known examples of this corrosion is the bonding of steel and stainless steel flanges. d) Cave

This corrosion occurs when the passive layer of carbon steel flanges is destroyed, for example due to the presence of corrosion products combined with a lack of oxygen. Therefore, this type of corrosion is common in small, narrow carbon steel flanges, such as seals under the ends of screws.

Cleaning and maintenance

To remove fingerprints, a washing solution is usually sufficient. Some cleaning product and Hastelloy C276 Hex Bolts manufacturer in India offer special products that provide better cleaning results by adding maintenance components. For stubborn stains, you can use a standard cleaning milk, which also removes chalk marks and discoloration. After cleaning, wash the surface of the stainless steel pipe with clean water.
