Stainless Steel L7 Fasteners are versatile metals that can be used for different applications. For instance, they are used for connecting heavy materials, such as steel and wood, to various types of construction materials, like highway structures. 


These durable fasteners can resist both acidic and alkaline corrosion, and come in different sizes to fit any need. You can find many different uses for them, such as in marine engineering and oil and gas industries.


The L7B specification covers several grades. The selection of a specific steel grade will depend on its application and design. In addition to that, it should be considered the low-temperature characteristics of the component. There are two types of AISI standards: AISI A320 and ASTM A320. 


The first specifies the minimum diameter, and the second specifies the Charpy impact energy absorption limit. These standards are important to manufacturers since they help them determine which steel grade is right for their application.
