316 Stainless Steel Sheet Metal
316 stainless steel sheet metal combines high corrosion resistance, mechanical strength, and excellent formability, making it suitable for a wide range of industrial, marine, chemical, food, architectural, and medical applications. Its availability in multiple surface finishes allows it to meet both functional and aesthetic requirements, providing long-lasting performance in demanding environments.
- Description
316 stainless steel sheet metal is an austenitic stainless steel widely recognized for its excellent corrosion resistance, mechanical strength, and durability. It is particularly suited for environments exposed to moisture, chemicals, and saline conditions, making it a preferred material for marine, chemical, and high-end architectural applications.
Chemical Composition
316 stainless steel includes iron, chromium, nickel, and molybdenum as key alloying elements:
| Element | Typical Range (%) |
|---|---|
| Chromium (Cr) | 16 – 18 |
| Nickel (Ni) | 10 – 14 |
| Molybdenum (Mo) | 2 – 3 |
| Carbon (C) | ≤0.08 |
| Manganese (Mn) | ≤2.0 |
| Silicon (Si) | ≤1.0 |
| Phosphorus (P) | ≤0.045 |
| Sulfur (S) | ≤0.03 |
Key Note: The addition of molybdenum significantly enhances 316’s resistance to chloride corrosion, making it superior to 304 stainless steel in harsh environments.
Mechanical Properties
| Property | Typical Value |
|---|---|
| Tensile Strength | 515 – 700 MPa |
| Yield Strength | 205 – 310 MPa |
| Elongation | ≥40% |
| Hardness (HRB) | 70 – 90 |
| Density | 7.98 g/cm³ |
These properties provide excellent strength, ductility, and formability, suitable for bending, cutting, stamping, and welding.
