How to select your stainless steel curtain rods, 304 or 316?

304 and 316 are both steel classifications of stainless steel. There are not many differences, in essence, both are stainless steel, but there still are some differences in detail. The grade of 316 is higher than 304 since 316 stainless steel contains the element Mo, which improves corrosion and wears resistance.
For 304 stainless sheets of steel, they have many advantages: suitable for processing, high toughness, high density, polished without bubbles, acid resistance, alkaline resistance, etc. Widely used in industrial, home decoration, food, Kitchenware, stainless steel curtain rods, etc.
For 316 stainless steel, they are more corrosion resistance, atmospheric corrosion resistance, and high-temperature strength, 316 stainless steel is used in seawater equipment, chemical, dye, paper, oxalic acid, fertilizer, production equipment, photographic, food industry, coastal area equipment, facilities, ropes, CD rods, bolts, nuts.
If stainless steel 316 is used in the food field, it is a little waste, since 304 is enough.
