Steel is an exceptional material suitable for a wide array of applications. However, it has a couple of key drawbacks. For one, standard carbon steels don’t have very good corrosion resistance. Additionally, the heat resistance can be an issue. If the application requires higher resistances, utilising stainless steel can be a good option. However, there is also an alternative to consider as well; aluminised steel. We want to have a closer look at it here. Then, we’re available if you want to order products from the best ERW steel tube supplier in the West Midlands.
What is it?
Are you familiar with galvanisation? It’s a process where you finish steel to give it a coating of zinc to enhance the properties. Aluminised steel is a similar idea, but has a coating of aluminium instead.
Applying aluminium to carbon steel is a really interesting idea. It means you can retain the strength and durability of the steel while also making it more resistant to corrosion and heat. The latter is especially notable. It means that products could effectively resist extremely high temperatures without problems with warping. It can offer an advantage over stainless steel. Even better, it is more cost effective.
Two options
Interestingly, there are actually two different types of aluminised steel. It all depends on the amount of aluminium being used. Crucially, it has an impact on the properties and thickness. Ask us for advice if you want to work with the best ERW steel tube supplier in the West Midlands.
The first option, type 1, is hot dip coated in a molten alloy of aluminium and silicon. As a result, it is 90% Al and 5-10% Si. The most notable thing here is the addition of silicon massively improves the heat resistance. Therefore, it is the best choice for applications such as cookware.
The second option is known as type 2. Instead of coating the steel in an alloy, here it is pure aluminium (99%). The key thing is the coatings tend to be thicker to provide more protection against wear and tear. So, it is the best option for a number of industrial applications, such as roofing, siding, and heat exchangers.
A word of warning
There is one crucial thing to keep in mind about aluminised steel; the protection may not last forever. Like galvanisation, wear and tear over time can compromise it. If scratches are deep enough they can expose the steel and allow corrosion.
It’s important to think carefully about the conditions when you decide what material to choose. If there is a high risk of mechanical damage such as scratches and scrapes, you may want to think about alternative materials.
