- Beschreibung
SS316 plate price per kg is generally higher than 304 stainless steel plate because 316 contains additional alloying elements that significantly improve corrosion resistance, vor allem im Marinebereich, chemisch, und chloridreiche Umgebungen. Although both are austenitic stainless steels, the raw material cost, Verarbeitungsanforderungen, and end-use performance of 316 make it a premium grade in many industrial sectors.
What Is SS316 Plate?
SS316 plate is an austenitic stainless steel plate containing chromium, Nickel, und Molybdän. The addition of molybdenum is the key reason why 316 stainless steel performs better than 304 in harsh environments. It offers excellent resistance to pitting corrosion, Spaltkorrosion, and chemical attack.
316 stainless steel plate is commonly used in marine equipment, chemische Verarbeitung, pharmaceutical tanks, and food-grade industrial applications where corrosion resistance is critical.
Chemische Zusammensetzung von 316 Edelstahlplatte
The alloy composition directly affects the price difference between 316 Und 304.
| Element | 316 Edelstahl (%) | 304 Edelstahl (%) |
|---|---|---|
| Chrom (Cr) | 16.0 – 18.0 | 18.0 – 20.0 |
| Nickel (In) | 10.0 – 14.0 | 8.0 – 10.5 |
| Molybdän (Mo) | 2.0 – 3.0 | — |
| Kohlenstoff (C) | ≤ 0.08 | ≤ 0.08 |
| Mangan (Mn) | ≤ 2.0 | ≤ 2.0 |
| Eisen (Fe) | Gleichgewicht | Gleichgewicht |
The presence of 2–3% molybdenum makes 316 significantly more expensive because molybdenum is a costly alloying metal.
Why SS316 Plate Price Per Kg Is Higher
1. Molybdenum Increases Raw Material Cost
The most important reason 316 stainless steel costs more is the addition of molybdenum. This element improves corrosion resistance in saltwater and acidic conditions but adds substantial alloy cost.
2. Higher Nickel Content
316 stainless steel usually contains more nickel than 304. Nickel is one of the major cost drivers in stainless steel production, and fluctuations in nickel prices directly affect 316 plate price per kg.
3. Bessere Korrosionsbeständigkeit
316 provides superior resistance to:
- Chloride corrosion
- Pitting corrosion
- Chemical processing environments
- Marine atmosphere
- Coastal structures
This enhanced performance makes 316 suitable for demanding industries where material failure is costly.
4. More Specialized Applications
Weil 316 is used in high-end industrial sectors such as pharmaceuticals, Meerestechnik, and petrochemicals, it is often produced to stricter specifications and surface quality standards, increasing production costs.
Vergleich der mechanischen Eigenschaften
| Eigentum | 316 Platte | 304 Platte |
|---|---|---|
| Zugfestigkeit | ≥ 515 MPa | ≥ 515 MPa |
| Streckgrenze | ≥ 205 MPa | ≥ 205 MPa |
| Verlängerung | ≥ 40% | ≥ 40% |
| Dichte | 7.98 g/cm³ | 7.93 g/cm³ |
| Korrosionsbeständigkeit | Exzellent | Gut |
Although the mechanical strength is similar, the corrosion resistance of 316 is much better in aggressive environments.
