M24 M27 Stainless Steel Hex Heavy Bolt Nut Washer A4-70 SS316L Corrosion-Resistant
M24 M27 Stainless Steel Hex Heavy Bolt Nut Washer A4-70 SS316L Corrosion-Resistant
Product Description:
The M12 and M14 stainless steel hex heavy bolts with nut washers are high-strength fasteners designed for use in industrial and commercial applications where durability and corrosion resistance are critical. Made from SS304, SS316, and SS316L, these bolts offer superior resistance to oxidation, rust, and corrosive environments, particularly in marine and chemical industries. With a high tensile strength and low maintenance requirements, these bolts provide long-lasting performance in challenging conditions.
Features:
• Premium Stainless Steel Materials: SS304 and SS316 materials provide excellent corrosion resistance, making these bolts ideal for environments exposed to saltwater, chemicals, or high humidity.
• Grade A4-70: The A4-70 grade indicates a high-strength bolt with a tensile strength of 700 MPa, ideal for applications that require secure, heavy-duty fastening.
• Long-Lasting Performance: Stainless steel’s inherent resistance to rust and corrosion makes these bolts an excellent choice for high-stress applications in challenging environments.
Advantages:
• Corrosion Resistance: These bolts excel in environments where other materials might fail due to rust or corrosion. Stainless steel, especially SS316 and SS316L, offers superior protection in saltwater or chemical environments.
• High Strength and Durability: With a tensile strength of A4-70 and the quality of SS304 and SS316, these bolts are designed to handle heavy loads and stressful applications, making them ideal for industries such as marine, chemical, and power generation.
• Low Maintenance: The corrosion-resistant nature of stainless steel reduces the need for frequent maintenance or replacement, resulting in cost savings over time.
Maintenance Tips:
• Regularly check bolts for any signs of loosening, particularly in high-vibration environments.
• Clean bolts with water or a mild detergent to remove any salt or chemical deposits that may accelerate corrosion.
• For applications exposed to extreme chemicals, apply a protective coating to further enhance the bolt’s resistance.
Applications
SS316L stainless steel is a low-carbon, austenitic stainless steel known for its excellent corrosion resistance and weldability. Here’s a detailed look at its corrosion-resistant properties and other characteristics:
Corrosion Resistance
Resistance to Pitting and Crevice Corrosion: SS316L contains 2.0-3.0% molybdenum (Mo), which significantly enhances its resistance to pitting and crevice corrosion. This makes SS316L particularly suitable for environments with high chloride content, such as marine and chemical processing applications.
Intergranular Corrosion Resistance: The low carbon content (≤0.03%) of SS316L reduces the risk of intergranular corrosion. During welding, carbon can combine with chromium to form chromium carbides, which can lead to intergranular corrosion. The low carbon content in SS316L minimizes this risk, making it ideal for welded structures without the need for post-weld heat treatment.
Atmospheric Corrosion: SS316L performs well in general atmospheric conditions, offering superior corrosion resistance compared to grades like 304 and 304L.
Resistance to Non-Oxidizing Acids: SS316L shows good resistance to corrosion in environments containing chlorides and other non-oxidizing acids. However, it is less resistant to strong oxidizing acids like nitric acid.
