304 Stainless Steel VS 316L Steel

Stainless steel is the most widely used watch material. At present, there are mainly 31 Lei 6-head stainless steel and 304 stainless steel. Among them, 316 stainless steel is the case material of medium and high-end watches. Because it contains molybdenum, it is more corrosion-resistant than 304, and its price is more expensive than 304 steel. It is usually called “stainless steel” in the industry.
Under normal circumstances, the “stainless steel” behind domestic brand watches is mostly 304 stainless steel. In the process of using 304 stainless steel, there is abrasion and a little rust.

304 stainless steel is the most common steel grade. As a widely used steel, it has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties; it has good hot workability such as stamping and bending, and no heat treatment hardening phenomenon (non-magnetic, Then use the temperature -196℃~800℃).

As a low-carbon series of 316 steel, in addition to having the same characteristics as 316 steel, it has excellent grain boundary corrosion resistance.

The corrosion resistance of 316 stainless steel is better than that of 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to corrosion by the ocean and corrosive industrial atmosphere.
