what is the meaning of sus316 stainless steel?
SUS316 is a high-grade austenitic stainless steel grade defined by the Japanese Industrial Standards (JIS), equivalent to the 316 stainless steel grade under American standards (ASTM). Due to the addition of approximately 2% to 3% molybdenum (Mo) to the composition of 304 stainless steel, it exhibits exceptional resistance to pitting corrosion as well as acid and alkali corrosion; consequently, it is frequently utilized in demanding marine environments or for medical devices. Welded sections of 316 stainless steel require post-weld annealing treatment; however, if 316L stainless steel is used, post-weld annealing is not required.
what is sus316 material equivalent?
SUS316 is a Japanese (JIS) stainless steel grade. Its primary global equivalent is AISI 316 (or SS316) in the United States. Other international equivalents include UNS S31600 and the European standard X5CrNiMo17-12-2 (or EN 1.4401).

What is the density of SUS316 material?
The density of SUS316 (equivalent to the AISI 316 grade under Japanese Industrial Standards) is typically 8.0 g/cm³ (i.e., 8,000 kg/m³). Depending on the specific processing method (such as annealing or cold drawing), its density may sometimes fluctuate between 7.98 g/cm³ and 8.03 g/cm³ (or approximately 0.289 lb/in³).
What is the thermal conductivity of SUS316?
At room temperature, the thermal conductivity of SUS316 (AISI 316) stainless steel ranges from 15.0 to 16.3 W/m·K. Compared to other metals, this value is relatively low; this characteristic makes SUS316 despite its poor thermal conductivity an excellent material for applications requiring thermal stability.
| Temperature | Thermal Conductivity (W/m-K) |
|---|---|
| 20°C (68°F) | 15.0 to 16.3 |
| 100°C (212°F) | 16.2 to 16.3 |
| 500°C (930°F) | 21.5 |
what is the difference between sus304 and sus316?
SUS304 is a general-purpose stainless steel, typically containing 18% chromium and 8% nickel; it is highly suitable for everyday applications involving minimal exposure to corrosive substances. SUS316 is a premium grade containing 16% chromium, 10% nickel, and 2% to 3% molybdenum; it is precisely due to the addition of molybdenum that it exhibits superior resistance to chloride and acid corrosion. It is frequently selected for use in harsh environments, such as coastal regions and chemical plants.
What is the difference between SCS14 and SUS316?
The primary difference between SCS14 and SUS316 is their manufacturing method: SCS14 is a cast stainless steel, while SUS316 is a wrought (rolled or formed) stainless steel. However, both share the exact same chemical composition and are often treated as Japanese Industrial Standard (JIS) equivalents to the American Grade 316 alloy.
