When buying a watch, many watches with metal straps usually indicate that the strap is 316 stainless steel or 316L stainless steel. Whether it is 316 stainless steel or 316L stainless steel, or other grade, it is only the grade of stainless steel material. At present, the grade of stainless steel materials used in watches are mainly 304 and 316, and the comprehensive performance of 316 is the most superior, so the price is slightly higher.

The characteristics of 316 stainless steel

316 stainless steel, also known as medical steel, is often used for steel plates that are shaped after fractures. Because of its strong corrosion resistance and good texture, it generally does not affect human’s skin. It is usually used to manufacture relatively expensive or good brand watch cases, crowns and straps.

How to clean stainless steel strap

The metal chain strap has become the first choice of many watch fans because of its sturdiness and unique metallic luster, but the chain strap watch has been worn for a long time, and the sludge accumulated at the joints of the watch or the mud mixed with sweat and dirt on the belt surface will emit a foul odor. So we must do the cleaning.

Method 1: Remove the watch strap and soak it in salt water for half a day. You will find that there are some black dirt deposits in the water. Then clean the watch with a toothbrush.

Method 2: Use a soft-bristled toothbrush with a little toothpaste or detergent to lightly brush the strap and seams, then rinse with water, wipe with a flannel, and dry the strap with a hair dryer.

After cleaning the watch, you should wear it carefully. Although the metal strap is hard, it does not mean that it is indestructible. The material of steel is easy to be printed on, and you should also pay attention to avoid scratching with sharp objects when wearing it.
