Characteristics of 317L stainless steel

In today’s developing industry, materials such as 317L stainless steel play an extremely important role. With main ingredients of chromium, nickel and molybdenum, combined with low carbon, this steel plate not only has good corrosion resistance but can also withstand high temperatures and is easy to process. 317L stainless steel has become the ideal choice for applications in the chemical, petroleum, medical and food industries, thanks to its unique combination of hardness, ductility and corrosion resistance. Let’s explore more deeply with Hoa Giang Inox about the characteristics and applications of 317L stainless steel plates through the article below.

What is 317L stainless steel?

317L stainless steel, also known as 317L stainless steel, is mainly composed of chromium, nickel and molybdenum, with low carbon content, creating significant corrosion resistance. Not only that, this combination creates an alloy with superior chloride rust resistance and higher general corrosion resistance than conventional grades such as 304/304L and 316/316L. In particular, in strongly corrosive environments containing sulfur, chloride and halide compounds, 317L exhibits better resistance than 316L.

With the low carbon content of 317L stainless steel, there will be no problem of intergranular corrosion during the welding process, thanks to the precipitation of chromium carbide. In addition, the addition of nitrogen also acts as a strengthening agent, allowing this alloy to be dual certified as 317 (UNS S31700). This demonstrates the diversity and versatility of 317L stainless steel in applications ranging from industrial to medical and chemical.

Characteristics of 317L stainless steel

Let’s join Hoa Giang Stainless Steel to learn some characteristics of 317L stainless steel 

Higher ductility: 

317L stainless steel generally has higher ductility than other steels, which means that the stainless steel has the ability to bend without breaking, allowing it to be used in applications where flexibility and adaptability are needed. response.

High forging hardening speed: 

  • 317L stainless steel typically has a high forging hardening rate, meaning it is capable of withstanding the forging process without excessive deformation, ensuring uniformity and smoothness of the crystal structure.

Higher hardness and durability: 

  • 317L stainless steel often has higher hardness and durability than conventional steels, so 317L stainless steel is suitable for applications that require high load and abrasion resistance.

Higher corrosion resistance: 

  • One of the most important advantages of 317L stainless steel plate is its high corrosion resistance, especially in acid, alkaline and seawater environments. This makes it the preferred choice for many applications in industries such as chemical, oil and gas, medical and food.

Inferior magnetic response:

  • 317L stainless steel generally has poorer magnetic response than other metals, which means it is suitable for medical and food applications.
