What is White Rust?

What is White Rust?

White rust, also known as wet storage stain or storage stain, is the white powdery substance that can form on the surface of a galvanised metal. This powder is a form of natural corrosion. This corrosion is damaging to both the aesthetic and the anti-corrosion layer...
What is Galvanisation and Why is it Used?

What is Galvanisation and Why is it Used?

Galvanisation is the process where a zinc coating is applied to steel or iron, in order to give it a protective layer, resistant to corrosion. The most common method of galvanisation is dipping the steel or iron into a pool of molten zinc. This method is called...
Annealing – Making Metal Ductile

Annealing – Making Metal Ductile

What is Annealing? Annealing is a heat treatment which alters the physical and often chemical properties of a metal to see it increase in ductility and decrease in hardness. Annealing involves heating the metal to a certain point and then slowly cooling. It is often...
Tempering – Making Metal Tough

Tempering – Making Metal Tough

What is Tempering? Tempering is a heat-treating process used to increase the ‘toughness’ of iron-based alloys so they are able to resist fracture. Typically, this process is done after the hardening process so some of the hardness can be reduced. Less hardness in a...
