Features of Stainless Steel 317L Screws

Stainless Steel SS 317L screws offer several notable features due to their unique composition and properties which include:

• Low Carbon Content: Carbon content in SS 317L screws is less than or equal to 0. 03% enhances weldability and minimizes the potential for the formation of carbides during the welding process.
• Enhanced Corrosion Resistance: 317L SS screws provide higher corrosion resistance than traditional stainless steels, especially in chloride-containing environments.
• Molybdenum Addition: Stainless Steel 317L screws contain 3-4% of molybdenum that greatly increases the material’s resistance to pitting and crevice corrosion.
• Acid Resistance: These screws are resistant to most types of acids such as sulfuric and phosphoric acids, making them useful in chemical industries.
• Marine Suitability: 317L SS screws are especially ideal for usage in marine environments due to their resistance to salt water and seawater.
• Stress Corrosion Cracking Resistance: These screws are less prone to stress corrosion cracking hence suitable for applications under high stress.
• High Strength: 317L SS screws provide high tensile strength and can be used in applications that require high strength and durability.
• Non-Magnetic: In the annealed condition, Stainless Steel 317L screws are typically non-magnetic, ideal for use where non-magnetic characteristics are desired.
• High-Temperature Stability: 317L SS screws resist fatigue and maintain their strength and stability while exposed to high temperatures, however, it is not as high as the grades such as 316Ti.
• Toughness: SS 317L screws shows some degree of hardness and ability to absorb shock at low temperatures for a range of climatic conditions.

These features contribute to the versatility and reliability of Stainless Steel 317L screws in various demanding applications.
