Based on SUS 316, SUS 316L reduces the influence of carbides precipitated in the sensitized state during welding by reducing the carbon content, thus optimizing the intergranular corrosion resistance. Therefore, it inherits the excellent corrosion resistance of SUS 316, while further improving its resistance to intergranular corrosion. In addition, due to the low carbon design, SUS 316L has a lower risk of intergranular corrosion during welding. The material also has good machining and welding properties, which can meet the needs of different fields.
The main chemical composition of JISG4304/4312 SUS 316L stainless steel includes chromium (Cr), nickel (Ni), molybdenum (Mo) and other elements. Among them, the content of chromium is 16.0%-18.0%, the content of nickel is 10.0%-14.0%, and the content of molybdenum is 2.0%-3.0%. In addition, it contains small amounts of manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), and carbon (C). The addition of these elements makes SUS 316L have excellent corrosion resistance and processing properties.
JISG4304/4312 SUS 316L stainless steel has excellent mechanical properties. Its tensile strength σb (MPa) ≥ 480, conditional yield strength σ0.2 (MPa) ≥ 177, elongation δ5 (%) ≥ 40, section shrinkage ψ (%) ≥ 60. These performance data show that SUS 316L can withstand large external forces, and can undergo a certain degree of plastic deformation without breaking when subjected to external forces.
Due to its excellent corrosion resistance, workability and weldability, JISG4304/4312 SUS 316L stainless steel is widely used in many fields. For example, in the chemical industry, it can be used to manufacture various chemical equipment and pipelines that can resist the erosion of various chemical substances. In the field of Marine engineering, due to its high corrosion resistance to seawater, it is often used in the manufacture of Marine parts and desalination equipment. In addition, SUS 316L also plays an important role in the fields of food processing, medical equipment and construction.
In summary, JISG4304/4312 SUS 316L, as a low-carbon high-alloy stainless steel, has excellent corrosion resistance and processing properties, which is ideal for many fields.
