M24 M27 Stainless Steel Hex Heavy Metal Bolt Nut Washer A4-70 SS316L Corrosion-Resistant

The M24 M27 Stainless Steel Hex Heavy Metal Bolt Nut Washer A4-70 SS316L Corrosion-Resistant is a high-performance fastener designed for use in industries requiring robust and durable components that can withstand challenging environmental conditions. This fastener system is typically employed in demanding applications such as marine, chemical, and industrial settings, where corrosion resistance and mechanical strength are paramount.

The key feature of this fastener lies in its material composition. Made from SS316L, a grade of stainless steel, the bolt, nut, and washer set are highly resistant to corrosion. Stainless steel is known for its durability and ability to withstand the effects of rust and environmental degradation, but SS316L takes this a step further. SS316L is a low-carbon variant of SS316, which improves weldability and reduces the risk of carbide precipitation. This material is particularly resistant to chloride corrosion, making it an ideal choice for applications in saltwater or highly acidic environments, such as those found in marine industries or chemical plants. The "A4-70" designation further signifies the material's strength and composition; the "A4" indicates a grade of stainless steel commonly used for highly resistant bolts and fasteners, while "70" refers to a yield strength of 700 MPa, a metric used to determine the material's ability to resist deformation under stress.

• Vibration Resistance - Due to their strong structure and tight threading, hex bolts offer excellent vibration resistance, making them suitable for environments with heavy vibration or shocks, ensuring a secure connection.
• Resistant to Environmental Changes - Stainless steel and galvanized hex bolts can withstand harsh outdoor environments, including exposure to marine conditions and chemicals. Their anti-corrosive and oxidation-resistant properties provide long-lasting performance.
• Aesthetic and Functional - Hex bolts, especially stainless steel varieties, offer a smooth, polished appearance, making them ideal for applications where aesthetics matter, such as in architectural designs and decorative structures.

Hex bolts are indispensable in various industrial and consumer applications due to their strength, versatility, and ease of use. They provide reliable and durable fastening solutions across multiple sectors.

Stainless steel material has the ability to resist atmospheric oxidation - that is, stainless steel, but also has the ability to resist corrosion in media containing acids, alkalis and salts - that is, corrosion resistance. Although stainless steel corrosion resistance is good, but not rust-free, if long-term exposure to corrosive environments, will eventually be corroded. Therefore, it is particularly important to understand the corrosion mechanism of stainless steel, the causes and maintenance methods.

Cr and Ni are the most important alloying elements of stainless steel to obtain corrosion resistance. When the Cr content of steel more than 10.5%, steel in the atmosphere basically does not rust. This is because Cr and Ni make stainless steel and oxygen in the air to generate a layer of very dense oxide film, so that the stainless steel passivation, reducing the corrosion rate of stainless steel materials in oxidising media, so that the corrosion resistance of stainless steel, and S30408, S31603 material Cr content of 16% or more, the corrosion resistance of stainless steel has been improved accordingly.

When the pipe is in the stray current or acid and alkali salt corrosive environment, the material itself since the passivation rate is lower than the rate of corrosion, with the role of time, there is the phenomenon of material destruction.
