Stainless Steel 317 and 317L are high molybdenum austenitic stainless steel grades, exhibiting excellent corrosion resistance, improved strength, and increased durability. These properties make them ideal for manufacturing fasteners - screws, nuts, bolts, washers, and more - used in various industries such as chemical processing, petrochemicals, and power generation.

Stainless Steel 317 Fasteners come in various types, including Hex nuts, Bolts, flat washers, Machine screws, Socket head screws, Jam nuts, and Lock nuts. Hex nuts and bolts are considered the most common. They are suitable for high-temperature and high-pressure applications where resistance to corrosion, heat, and crevice corrosion is necessary. Stainless Steel 317 Machine Screws, however, are perfect for applications in which the material must be driven into a pre-tapped hole or nut. They are also ideal for applications where the screws must maintain a tight grip without loosening or wiggling over time.

Stainless Steel 317L Fasteners find extensive use in the chemical processing, power generation, and petrochemical industries, among others. The fasteners are highly resistant to corrosive environments and are suitable for chemical reactors, heat exchangers, pipelines, condenser tubes, and other vital components used in these industries. They are also ideal for applications requiring high yield strength and toughness at elevated temperatures, making them excellent for gas turbines and power generation equipment.
