18mm 19mm 316 316l Stainless Steel Rod 1/16" 1/2 Inch 1/8 Inch 2 Inch 904L 316L Polish Bright Black

Both 904L and 316L stainless steel have similarities, but they also have some very distinct differences. The most obvious ones are their composition and cost.
904L stainless steel is made up of iron, chromium, nickel, molybdenum, copper, nitrogen, and manganese, while 316L consists of iron, chromium, nickel and molybdenum. In terms of cost, 904L is more expensive than 316L due to its higher levels of nickel and molybdenum content.
In terms of physical properties, both offer excellent resistance to corrosion in a variety of environments, including marine environments and acidic atmospheres where other steels would fail quickly. Both also have high tensile strength and durability when exposed to harsh conditions. However, 904L has significantly better corrosion resistance than 316L due to its higher levels of nickel and molybdenum content which makes it ideal for high-stress applications such as chemical processing equipment or food processing machinery. Additionally, 904L also has a higher temperature tolerance than 316L making it suitable for use in high-temperature environments such as oil refineries or nuclear power plants.
