Before you get to know what a stainless steel handpan is like, it would be wise to know how stainless steel is different from other metals that are usually used for drums or pans. Most people do not understand that SS or stainless steel is quite different from a single metal like iron. Steel is an alloy and could have various elements in differing strengths and percentages. In cases where there is more iron, the chances of faster rusting are higher. This is why you might see that poor quality steel starts developing a blackish or brownish coating, especially at the seams or joints. This is because the quality of steel is low, and the content of iron is higher. Some of the best steel that is used can be found in the medical sector, where surgical steel is usually of the highest quality.
Chromium
The main ingredient in steel that ensures that corrosion does not take place, is chromium. The higher the percentage of chromium, the greater is the possibility of the product remaining free from rust. In fact, even an 18% chromium inclusion could ensure a good quality of steel. For a hang drum that needs to give out the right range of notes and tones, it is important that the quality of steel is good; this means that the amount of chromium should be high. You must also understand that when this element is on the higher side, it will act as a barrier to any kind of oxidation process. It, therefore, protects the metal and the instrument from humidity and other natural elements.
Tools
When you are trying to work with a metal-like SS, you should remember that specialized cutting and shaping instruments are required. For instance, you might require a mallet that is used to make the indentations. Since a musical instrument is quite delicate, it is common to find that they are entirely handmade and very little mechanised help is used. This means that the process is a long drawn out one and cannot be completed soon. With the right kind of tools and equipment, it is possible to come out with the right kind of stainless steel pan or drum that will produce the desired sound and effect.
Once you are sure about the quality of the SS used, run a test to see what the sound is like. If you are satisfied that it is of the right timbre, acquire it right away.
