'L' stands for low carbon. 316L is used to avoid corrosion problems caused by welding and does not develop surface rust.Stainless Steel does not corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof. It typically has a silver sheen, but, unlike silver, it will not corrode and it is not susceptible to scratches, dings or dents. You can clean this item using mild soap and water or a lint free polishing cloth is recommended. Use a polishing cloth specifically designed for stainless steel. Enameling cannot take heat from torches, over-polishing, steaming or ultrasonic cleaners. Do not use harsh chemicals or abrasive cleaners.
