When selecting stainless steel with high corrosion resistance, stainless steel grades 316 or 316L are often preferred. These steels contain molybdenum, which provides high corrosion resistance.
Here are the main characteristics of these two grades:
1. Stainless Steel 316 (AISI 316):
• Contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum.
• Offers high corrosion resistance in aggressive environments such as seawater, chemical agents, and salty conditions.
• It is also resistant to high temperatures.
2. Stainless Steel 316L (AISI 316L):
• Has a similar chemical composition to 316 but with lower carbon content (L stands for "Low Carbon").
• The low carbon content reduces post-weld corrosion and makes the steel more weld-friendly.
• Particularly preferred for welded or high-temperature applications.
These stainless steel grades are used in many applications, including marine, chemical industry, food processing, and medical devices. However, it is important to consult with a materials engineer or specialist to assess your specific application requirements and choose the most suitable stainless steel grade for your design, as each application may have different conditions.
