What are the characteristics of 317 stainless steel?
317 Stainless Steel is a molybdenum-containing austenitic stainless steel that offers greatly improved resistance to chemical attack compared to traditional chromium-nickel austenitic stainless steels such as 304 and 316. Alloy 317 also exhibits higher creep strength, stress to fracture, and tensile strength at higher temperatures than conventional stainless steels. In addition, the higher the content of these elements, the higher the corrosion resistance in environments containing chlorides or other corrosive chemicals. 317 stainless steel has the following characteristics:
- Austenitic basic steel, the most widely used;
- Excellent corrosion resistance and heat resistance;
- Excellent low temperature strength and mechanical properties;
Compared with 316L stainless steel plate, 317 stainless steel plate has good seawater resistance and SCC resistance.

How is the corrosion resistance of 317 stainless steel?
While most grades of stainless steel have good corrosion resistance, 317 stainless steel goes a step further, offering a higher level of corrosion resistance. This makes it ideal for applications where there is a risk of exposure to aggressive chemicals or the environment.
The increased resistance level is due to the higher molybdenum content in 317 stainless steel. Molybdenum is a key element in stainless steel formulations because it increases resistance to pitting and crevice corrosion. It also contributes to the overall strength of the alloy.
In addition to its impressive corrosion resistance, 317 stainless steel has other desirable properties. It has good weldability and forming characteristics, making it easy to process. It is also highly ductile, which means it can be cold worked extensively without becoming brittle.
Overall, 317 stainless steel is an excellent choice for applications where corrosion resistance is a critical concern.
What are the advantages and disadvantages of 317 stainless steel?
317 stainless steel is a chromium-nickel-molybdenum austenitic stainless steel with good corrosion resistance. It has a higher nickel content than 316 stainless steel and contains molybdenum, giving it better corrosion resistance in certain chemicals and environments. But 317 stainless steel is more expensive than 316 stainless steel.
In conclusion, 317 stainless steel is a cost-effective choice for a variety of applications. It has excellent corrosion resistance, making it ideal for a range of industries from food processing to oil and gas. Its strength makes it suitable for structural components and outdoor environments, while its low cost makes it widely applicable to many businesses with limited budgets. For these reasons, 317 stainless steel is an excellent choice if you are looking for a reliable material that offers several benefits.
What are the uses of 317 stainless steel?
317 (18Cr-12Ni-3.5Mo) stainless steel has better pitting resistance than 316 steel. 317 stainless steel is used for printing and dyeing equipment materials.
317 stainless steel is a chromium-nickel-molybdenum austenitic stainless steel with good corrosion resistance. Due to its high molybdenum content, it can be used in environments where chlorides are present, such as offshore and marine applications. 317 stainless steel is also a good choice for applications requiring high temperatures, such as heat exchangers and furnaces.
Stainless steel is gaining popularity in manufacturing for its durability and corrosion resistance. While there are many different types of stainless steel, one of the most versatile is 317 stainless steel. This alloy has a range of properties that make it ideal for a variety of industries, including those that require constant exposure to chemicals or high temperatures
317 stainless steel is an austenitic chromium-nickel stainless steel with low carbon content. It is highly corrosion resistant and has higher creep and stress rupture properties than other austenitic stainless steels. 317 is often used in process streams containing chlorides or other corrosive chemicals.
How to maintain 317 stainless steel ？
