Vetypelkistys

Vetypelkistys, also known as type pelkistys, is a process used in the production of steel, particularly in the manufacture of stainless steel. The term "vetypelkistys" is derived from Finnish, where "vety" means hydrogen and "pelkistys" means reduction. The process involves the removal of oxygen from the steel to create a more pure and corrosion-resistant material.

The process begins with the addition of a reducing agent, such as hydrogen or carbon monoxide, to the molten steel. This agent reacts with the oxygen present in the steel, forming water vapor or carbon dioxide, which is then removed. The resulting steel is free of oxygen and is known as reduced steel or stainless steel.

Vetypelkistys is a crucial step in the production of stainless steel, as it significantly enhances the material's resistance to corrosion and oxidation. The process is typically carried out in a controlled environment to ensure the safety and efficiency of the operation. The resulting stainless steel is widely used in various industries, including construction, automotive, and aerospace, due to its excellent corrosion resistance and durability.
