SS316L Corrosion-Resistant M24 M27 Heavy Metal Bolt Nut Washer Set
– Built for Harsh Conditions
Product Description:
This headline highlights the superior durability of the M24 and M27
fasteners, constructed from SS316L stainless steel, which is known
for its excellent corrosion resistance. These fasteners are
engineered to endure harsh conditions, including exposure to
saltwater, chemicals, and other corrosive elements. This makes them
ideal for marine, offshore, and chemical plant applications, where
protection against rust and deterioration is critical for long-term
performance. The set provides a complete solution to securing
heavy-duty machinery or structures in such environments, offering
peace of mind in industries requiring robust and reliable
components.
Material and Corrosion Resistance
The A4-70 grade designation in this headline refers to a
high-strength, corrosion-resistant stainless steel composition,
ensuring these fasteners perform well in challenging environments.
The M24 and M27 bolts, nuts, and washers have been designed to
withstand mechanical stress, making them suitable for heavy-duty
structural and industrial applications. Their high tensile strength
(700 MPa yield strength) means they can bear significant loads
without failure, making them perfect for critical installations,
especially in extreme conditions like offshore rigs or chemical
plants where both strength and durability are essential.
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:
Mechanical Properties
Tensile Strength: SS316L has a tensile strength of approximately 485 MPa.
Yield Strength: The yield strength is around 205 MPa.
Elongation: It has an elongation of about 60%, indicating good ductility.
Applications
Marine and Offshore Engineering: SS316L is commonly used in marine environments, such as ship
fittings and desalination equipment, due to its ability to resist
seawater corrosion.
Food Processing and Pharmaceutical Industries: Its excellent corrosion resistance and sanitary properties make
SS316L widely used in food processing equipment and pharmaceutical
machinery.
Medical Devices: The biocompatibility of SS316L makes it an ideal material for
manufacturing implants and surgical instruments.
Chemical Processing Equipment: SS316L is used in chemical processing equipment where resistance
to various chemicals is required.
Comparison with Other Stainless Steels
Compared to SS316: SS316L has a lower carbon content, which provides better
corrosion resistance after welding or in high-temperature
environments. SS316, on the other hand, offers higher strength at
elevated temperatures (above 800°F).
Compared to SS304: SS316L has superior corrosion resistance, especially in
chloride-rich environments. SS304 has a higher carbon content,
which makes it more susceptible to intergranular corrosion after
welding.
Summary
SS316L stainless steel is highly valued for its excellent corrosion
resistance and weldability, making it ideal for demanding
environments, particularly those involving welding and high
corrosion risks. Its low carbon content minimizes the risk of
intergranular corrosion, while the addition of molybdenum enhances
its resistance to pitting and crevice corrosion. This makes SS316L
a preferred choice for marine, chemical, and food processing
applications, as well as for medical devices.
