316 stainless steel screws or 304 stainless steel screws good?

316 stainless steel screws are better than 304 stainless steel screws, the two stainless steel screws are composed of 316 stainless steel screws than 304 stainless steel screws more Mo elements, its corrosion resistance, high temperature performance is better than 304 stainless steel, the other performance is the same.

316 stainless steel screws are mainly used in food industry and surgical equipment. Molybdenum is added to the screws to obtain a special corrosion resistant structure. It is also used as “Marine steel” because of its better chloride resistance than 304 stainless steel screws. ‍ 304 stainless steel screw is stainless steel cover type, material composition for OCr18Ni9316L, is austenitic stainless steel; Material 316 is OOCr12Mo2Ti, a titanium low carbon stainless steel, alkali resistant and acid resistant (except for medium containing chloride ion). From the corrosion resistance, 316 stainless steel screws are better, from the price point of view, 316 stainless steel screws are more expensive than 304 stainless steel screws, but from the use, it is about to see the designer’s design, only in line with the design requirements is a good screw.

From the point of view of saving money and energy, 304 stainless steel screws can be used as far as possible 304 stainless steel screws, so, 304 stainless steel screws and 316 stainless steel screws can not say who is better, can only say suitable is good.
