You may be seeing stainless steel everywhere around you, and you began to wonder what makes this material so unique that you seem to find it, not only in construction sites, pipes and even in your kitchen! Let’s take a closer look at these stainless steel facts – some, you may even find surprising.

Stainless steel’s magnetic properties:
You may find that some stainless steel are magnetic. Stainless steel is divided into groups and each differs in the composition of alloys and atomic arrangement which causes the variation of the steel’s magnetic properties. Generally, ferritic types are magnetic and austenitic types are usually not.

Stainless steel can stain:

Stainless steel is composed of material that resists corrosion and oxidation, giving it the ability to “self-repair” when exposed to oxygen and moisture, however, its protective oxide film coating wears out over time. This is why, contrary to its name, stainless steel can stain. It is, therefore, important to ensure sufficient oxygen contact and proper handling and maintenance when working with this material.

Stainless steel can be recycled:

According to American Iron and Steel Institute, 88% of stainless steel gets recycled and every 2 out of 3 tons of newly made steel were made from recycled steel. The same goes with its by-products, like mill scale, processing liquid and steelmaking slags. Steel making sludge and dust are also re-used to create zinc and similar other products.

Stainless steel can be used as “Soap”:

The ability of stainless Steel to neutralize or reduce pungent scents and odors, is the main reason why you find them in your kitchen.  This characteristic is a result of sulfur compounds, binding with various with various elements.

Additional fact: Did you know that the Eiffel Tower’s height is approximately 6” shorter during the winter? The Eiffel tower stands at 984 feet tall (minus the antenna) during the summer. This is due to the stainless steel’s reaction to temperature change. It expands and contract as the temperature varies. This is one of the major factors that the construction industry takes note of, before initiating construction using this material.

It is for being low maintenance and the above mentioned unique qualities, that stainless steel material has found its way in different industries. For more information, don’t hesitate to Contact Us at Chuan Kok Hardware & Machinery Pte Ltd.
