Detailed Solution

The above statement is true.
The bellows are used to pump air to keep the coals burning. The bellows were invented in Medieval Europe and were often used to speed up combustion, such as in a blacksmith or iron smith's forge, or to operate pipes or reed pipe bodies. Bellows can be made from various stainless steel, with 300 series steel plates being the most common. Stainless steel has excellent tensile strength, making it easy to maximise travel and reduce package size. Stainless steel also has excellent corrosion resistance in many environments and media. Industrial and mechanical bellows are widely used in industrial and mechanical applications such as bar bellows, machine gap covers, elevator covers, and rail covers to protect rods, bearings, and washers from dirt. In addition, the bellows are widely used on buses and trams with joints to cover joints where the car bends.
