316L stainless steel, similar to 316 stainless steel, has a lower amount of carbon of no more than 0.03% in its composition. This is meant to reduce the risk of carbon precipitation, to make a better choice for welding to achieve maximum corrosion resistance.

304 stainless steel, as one of the most commonly used types of stainless steel, is an outstanding material when it comes to corrosion resistance, heat resistance, low temperature strength and mechanical properties. In addition, it has exceptional hot-workability so it leaves no heat treatment hardening phenomenon.

Similar to 304 stainless steel, 304L stainless steel has one key difference in its chemical composition. The maximum carbon content of 304 stainless steel is 0.08%, whereas grade 304L stainless steel has a maximum carbon of only 0.03%. This is why the “L” in 304L can be interpreted as extra-low carbon. It is usually used to produce equipment and parts that demand better corrosion resistance and formability.

316 stainless steel has extra 2-3% molybdenum, in addition to iron, chromium and nickel. Molybdenum significantly leads to better performance of 316 stainless steel in certain corrosive environments containing chlorides. So it is a very common choice in situations requiring higher corrosion resistance.

309 stainless steel is a stainless steel material featured by excellent corrosion resistance and high temperature performance. 309 stainless steel bars are widely used as manufacturing parts in aviation, chemical industry, petroleum, food processing fields
