Stainless Steel Fasteners
Stainless steel fasteners are commonly used in various applications due to their corrosion resistance and durability. AFT Fasteners provides a large inventory of stainless steel screws, nuts, washers, anchors, bolts pins & more.
The grades of stainless steel used for fasteners can vary depending on the specific requirements of the application. Here are some common grades of stainless steel for fasteners:
Stainless Steel Grade 18-8 (A2): This grade is also known as AISI 304 or ASTM A2. It contains approximately 18% chromium and 8% nickel, providing good corrosion resistance and moderate strength. Grade 18-8 stainless steel fasteners are commonly used in general-purpose applications.
Stainless Steel Grade 316 (A4): This grade is also known as AISI 316 or ASTM A4. It contains approximately 16-18% chromium, 10-14% nickel, and 2-3% molybdenum. Grade 316 stainless steel fasteners offer excellent corrosion resistance, particularly in marine environments or applications involving exposure to chloride solutions.
Stainless Steel Grade 410: This grade is a martensitic stainless steel with 11.5-13.5% chromium. Grade 410 stainless steel fasteners have high strength, good hardness, and moderate corrosion resistance. They are commonly used in applications where strength and wear resistance are essential.
Stainless Steel Grade 304L (A2-50): This is a low-carbon version of Grade 304 (18-8) stainless steel, providing improved resistance to sensitization during welding. It contains approximately 18% chromium and 8% nickel. Grade 304L stainless steel fasteners are often used in applications that involve welding or where low carbon content is preferred.
Stainless Steel Grade 316L (A4-50): This is a low-carbon version of Grade 316 stainless steel, offering improved resistance to sensitization during welding. It contains approximately 16-18% chromium, 10-14% nickel, and 2-3% molybdenum. Grade 316L stainless steel fasteners are commonly used in applications that require enhanced corrosion resistance and weldability.
These are just a few examples of stainless steel grades used for fasteners. Other grades, such as 304H, 321, 347, and 2205 duplex stainless steel, are also available for specific applications with unique requirements. It's important to consult the specific needs of your application and consider factors such as corrosion resistance, strength, and environmental conditions when selecting the appropriate stainless steel grade for your fasteners.
