Stainless steel in nickel alloys

Here we present information for those who want to learn more about nickel as a material, and nickel alloys with their versatile applications. Nickel alloys are a valuable group of materials with a range of unique properties that make them indispensable in various industries.

 

Does stainless steel contain nickel?

Stainless steel is a metal alloy containing, for example, nickel, chromium and iron. Nickel gives the steel its corrosion resistance and mechanical strength. It is used in cookware, medical equipment, construction and high temperature applications due to its unique properties.
There are many different types of stainless steel, such as austenitic, ferritic, martensitic and duplex. These each have their own composition and properties. The choice of material depends on the application and environment.

Other important components of stainless steel

  • Chromium: In general, stainless steel contains at least 10.5% of chromium. Chromium creates a thin, passive surface film of chromium oxide that protects the material from further corrosion. This film can repair itself if damaged, contributing to the steel's corrosion-resistant properties.
  • Carbon: Used in varying amounts to improve the hardness and strength of steel. However, too much carbon can reduce corrosion resistance.
  • Molybdenum: Further improves corrosion resistance, especially to chloride ions, which is useful in marine and chemical environments.
  • Manganese and silicone: Used as alloying elements and contribute to the structural properties of steel.

The advantages of nickel + steel

Steel and nickel alloys are materials that combine the strength of steel with the corrosion and temperature resistance of nickel. They are mainly used in demanding environments where these properties are crucial, such as in the chemical industry and high temperature applications. These alloys are also known for their mechanical strength and are often used for components subject to high mechanical loads.

  • High heat resistance: Nickel alloys can withstand high temperatures without losing their mechanical properties, making them ideal for applications in high temperature areas.
  • Corrosion resistance: They have an ability to resist corrosion and oxidisation processes, making them suitable for use in aggressive environments.
  • Strength and toughness: Nickel alloys offer excellent toughness and strength, making them suitable for demanding applications where mechanical performance is prioritised.

Properties of nickel

Nickel is an element with atomic number 28 and the chemical name Ni. It is an element that has specific properties that make it useful in a variety of fields.
Corrosion resistance is one of nickel's main strengths. This means that they can be easily used in environments where moisture and chemicals are constantly present, without risking degradation and damage.

Nickel can be reused

Nickel is also known for its high heat resistance. It can withstand extreme temperatures without losing its properties, making it ideal for use in applications where high temperatures are part of everyday life. Nickel can be reused an unlimited number of times.
