Features of stainless steel

Metal allergy is caused by metal ions that dissolve from metal components due to moisture such as sweat. Stainless steel is produced by combining the chromium and oxygen contained in it.Passive filmThe surface is covered with a thin oxide film. It is said that this oxide film makes it difficult for metal ions that cause metal allergies to dissolve, making it difficult to cause allergic reactions. This oxide film protects stainless steel from rusting.
In addition, it is harder than silver or brass.Resistant to scratches even when worn on a daily basisIt has the following characteristics. The hardness is slightly harder than brass fittings, and the finish is solid and strong.

Stainless steel is not a precious metal such as gold or platinum, but an alloy whose main component is iron and contains chromium. Although it is an artificially produced metal and is relatively inexpensive, it is a very stable metal. It is used in a variety of everyday situations such as tableware and watches, and its color is a little darker and heavier than silver or rhodium.

Titanium is a metal whose surface is covered with an oxide film and has similar properties as stainless steel. Titanium is said to be expensive due to the special manufacturing process from raw materials and the difficulty of processing. The color is dark, like stainless steel, and has a slightly matte appearance.

On the other hand, SUS304 is used in very familiar things such as tableware that we eat every day and watch straps. It is highly safe and easier to process than SUS316L, so it is commonly used as a material for delicate accessory parts.
