High corrosion-resistant stainless steels [TOKUSHU KINZOKU EXCEL CO., LTD.]
SUS316L, SUS316
It is stainless steel with improved corrosion resistance, making it suitable for drawing applications.
This is a steel grade in which the nickel content of SUS 304, a representative austenitic stainless steel grade, is increased and molybdenum is added to further improve corrosion resistance. SUS304 with increased nickel and molybdenum addition= SUS316: Improved corrosion resistance (pitting corrosion, stress corrosion cracking, etc.) SUS316 with higher nickel, lower carbon = SUS316L ... + Improved intergranular corrosion resistance The "L" in SUS316L stands for low carbon. Highly corrosion-resistant stainless steel is also suitable for drawing applications because of its low carbon content and high nickel content, resulting in low hardness in the annealed state and less work hardening. Note that although non-magnetic in the solution heat-treated state, it becomes weakly magnetic after strong working. This grade of steel is difficult to obtain due to its relatively small distribution volume among thin stainless steels, but we also manufacture such materials with custom specifications. Please feel free to contact us for foil with a thickness of less than 0.10 mm, special dimensions, hard finishes, short delivery times, small lots, etc. For more details, please refer to the related links or feel free to contact us.

Line up（2）
| Model number | overview |
|---|---|
| SUS316L | This material has a lower carbon content than SUS316, improving its drawability and resistance to intergranular corrosion. |
| SUS316 | Due to the increase in Ni and the addition of Mo, this material has excellent corrosion resistance. It is often used for drawing applications, but it is characterized by a low hardness in the annealed state and low work hardening due to its low carbon content and high nickel content. |
Company information
TOKKIN's materials are everywhere around you, even though you can't see them! TOKKIN is a precision metal materials manufacturer founded in 1940. We produce high-quality, high-value-added materials according to the each customer specifications, such as processing metals into thin strips or sheets by cold rolling to improve mechanical properties, cladding different materials to form a single material, and applying resin or solder to metal surfaces. Our materials are used in a wide range of products, from daily life gadgets such as smart devices, PCs, automobiles, and game consoles to industrial equipment such as semiconductor manufacturing equipment, medical equipment, and textile machinery. Although our material is mostly invisible, it plays an indispensable role in ensuring that the products and their supporting components function well. High-functional materials, made possible only by TOKKIN, support the technologies that are created one after another behind the scenes.
