Chemical Composition of Austenitic Stainless Steel S31603 00Cr17Ni14Mo2

The chemical composition of Austenitic stainless steel S31603 00Cr17Ni14Mo2

Austenitic stainless steel S31603 00Cr17Ni14Mo2 is a kind of stainless steel widely used in industry. It belongs to the general grade of 304. Its chemical composition is as follows:

1. Carbon (C) ≤ 0.08%,

2. Manganese (Mn) ≤ 2.00%,

3. Silicon (Si) ≤ 0.75%,

4. Chromium (Cr) 17-20.00%,

5. Nickel (Ni) 11-15.00%,

6. Molybdenum (Mo) 2.0-3.00%,

7. Phosphorus (P) ≤ 0.045%,

8. Sulfur (S) ≤ 0.030%,

9. Nitrogen (N) ≤ 0.10%.

The excellent corrosion resistance of the austenitic stainless steel S31603 00Cr17Ni14Mo2 depends on the amount of chromium, molybdenum and nitrogen. Chromium increases the corrosion resistance and strengthens the oxide film. Therefore, the corrosion resistance of this stainless steel is very strong. Because the molybdenum is added, the corrosion resistance after reducing the high temperature of austenitic stainless steel is improved greatly, so as to resist the erosion of sulfuric acid and process acid. In addition, adding a small amount of nitrogen improves the corrosion resistance, especially in reducing the chloride-rich medium, so as to have a better corrosion resistance.

In addition to its excellent corrosion resistance, austenitic stainless steel S31603 00Cr17Ni14Mo2 has a certain strength, good weldability, and is easy to form. The strength of this steel is slightly higher than that of type 304 stainless steel. It is because of the good balance between the austenite and ferrite that the austenitic stainless steel S31603 00Cr17Ni14Mo2 can be welded very well. After welding, high welding strength and toughness can be obtained. It has good ductility and can be easily formed into different shapes.

Due to its excellent corrosion resistance, austenitic stainless steel S31603 00Cr17Ni14Mo2 is widely used in industry, such as making chemical storage tanks, process equipment, and marine equipment. In the construction and decoration industry, it is also widely used in outdoor furniture and architecture.

In conclusion, the austenitic stainless steel S31603 00Cr17Ni14Mo2 has excellent corrosion resistance, good weldability and formability, which makes it suitable for a wide range of applications.

316L stainless steel (00Cr17Ni14Mo2) is an improved version of the 316 stainless steel. It is an austenitic chromium-nickel-molybdenum stainless steel with low carbon content.
