High corrosion resistance stainless steels SUS316L SUS316

SUS316L and SUS316 are two types of highly corrosion-resistant stainless steel materials, mainly used in fields that require corrosion resistance. SUS316L is a low-carbon stainless steel with a lower carbon content, which is more suitable for intergranular corrosion in the welding heat affected zone. It is commonly used in environments such as chemical industry and pharmaceuticals.

In contrast, stainless steel SUS316 has a slightly higher carbon content and typically performs well in high-temperature and highly corrosive environments, such as marine equipment and chemical equipment. It has added 2% molybdenum to improve its corrosion resistance, especially exhibiting excellent performance in chloride environments.

Both types of stainless steel have good corrosion resistance, mechanical properties, and processability, and are widely used in fields such as food processing, medical equipment, and shipbuilding. The choice between stainless steel SUS316L or SUS316 depends on specific requirements, such as whether stronger corrosion resistance is needed and whether high-temperature environments are involved.

In some special cases, such as in high temperature, high pressure, or highly corrosive media, it is recommended to use stainless steel SUS316 or SUS316L to ensure the reliability and durability of the equipment or structure. In the selection process, it is necessary to consider environmental conditions, cost-effectiveness, and material characteristics to make the most suitable choice.
