The rapid development of robotics is transforming industries such as defense, medical care, and disaster response. Among the materials selected for robot manufacturing, stainless steel plays a critical role in ensuring strength, reliability, and adaptability. In particular, 316 stainless steel bars are widely recognized as one of the most suitable materials for special robots due to their superior corrosion resistance and mechanical stability.
Key Properties of 316 Stainless Steel
316 stainless steel belongs to the austenitic stainless steel family, enriched with molybdenum, which enhances corrosion resistance compared to 304 stainless steel. This makes it highly effective in harsh and corrosive environments, where standard materials may fail.
| Property | 316 Stainless Steel |
|---|---|
| Chemical Composition (Cr/Ni/Mo) | 16–18% Cr, 10–14% Ni, 2–3% Mo |
| Tensile Strength | 515 MPa (min) |
| Yield Strength | 205 MPa (min) |
| Hardness | ≤ 95 HRB |
| Corrosion Resistance | Excellent in seawater and chemicals |
| Heat Resistance | Up to 870°C |
These properties allow 316 stainless steel to withstand not only mechanical stress but also extreme working conditions such as high humidity, salt spray, and chemical exposure.
