What is the difference between SUS and SS 316 stainless steel?

SUS and SS both represent the standards for stainless steel. SUS is an abbreviation for Japanese Industrial Standard, used to refer to various metal materials, including stainless steel. SS stands for stainless steel, which is not a specific national or regional standard and is usually used as an internationally recognized term.

SUS 316 is a high-quality and highly corrosion-resistant stainless steel widely used in fields such as chemical, medical, and food processing. Its main components include 18% chromium, 10% nickel, and 2% molybdenum, giving it excellent corrosion resistance, especially in acidic and chloride environments.

When using the term 'SUS 316', it usually refers to stainless steel 316 that complies with JIS standards. In contrast, "SS 316" is more inclined towards international standards and may comply with ASTM (American Society for Testing and Materials) or other international standards. Although both refer to stainless steel 316, the specific specifications, production processes, and standards are slightly different, and the appropriate specifications and standards need to be selected according to the specific situation.

Whether it is SUS 316 or SS 316 stainless steel, their basic composition and performance characteristics are basically the same, but there may be some slight differences in specific standards and specifications. When selecting and using, it is important to pay attention to whether the material meets the required material requirements and relevant standards and specifications to ensure that the quality and performance of the material meet expectations.
