nikkeliteräkset

Nikkeliteräkset, also known as nickel steels, are a group of steel alloys that contain nickel as a primary alloying element. The addition of nickel to steel significantly alters its properties, often leading to improved toughness, ductility, and hardenability. These steels are known for their excellent strength and corrosion resistance, especially in environments where other steels might fail.

The most common type of nikkeliteräs is 3.5% nickel steel, which is known for its good toughness at low temperatures. Higher nickel content steels, such as those containing 9% or 18% nickel, exhibit unique properties. For instance, 9% nickel steel is used in cryogenic applications due to its exceptional strength and toughness at very low temperatures. 18% nickel maraging steels are a class of ultra-high-strength steels known for their remarkable combination of strength, toughness, and ductility, achieved through a precipitation hardening process.

Nikkeliteräkset find widespread applications across various industries. They are used in the aerospace industry for aircraft components, in the automotive sector for gears and shafts, and in the marine industry for shipbuilding and offshore structures. Their resistance to corrosion makes them suitable for chemical processing equipment and food handling machinery. The specific composition and heat treatment of nikkeliteräkset are carefully controlled to achieve the desired performance characteristics for their intended use.
