M16 M18 Weld Nut Carbon Steel Grade 4.8 ASTM A194 Weld Hexagon Nut White Zinc Plated

M16 M18 Weld Nut Carbon Steel Grade 4.8 ASTM A194 Weld Hexagon Nut White Zinc Plated

Product Description:

This weld nut is made from high-quality carbon steel in grade 4.8, and it is designed to meet ASTM A194 specifications. This ensures the weld nut complies with high-quality manufacturing standards, making it suitable for use in a variety of industrial applications, such as automotive, machinery, and heavy construction. The sizes available are M16 and M18, catering to large-scale applications that require robust fastening solutions.

Grade 4.8 carbon steel is a medium-strength material that is commonly used in applications that do not experience extreme loads but still require reliability and strength. It is ideal for general-purpose fastening and provides solid performance in routine machinery, automotive, and construction applications. The ASTM A194 standard ensures that the weld nut meets rigorous mechanical and chemical property requirements, ensuring a reliable and safe fastening solution.

The white zinc plating provides an extra layer of protection against corrosion, ensuring the weld nut retains its functionality and appearance even in harsh environments. Zinc plating is a commonly used method for increasing the lifespan of metal components by providing a protective layer that helps prevent rust and oxidation. The white zinc finish not only improves the corrosion resistance but also gives the weld nut a distinct, bright finish that is visually appealing.

This weld nut is perfect for applications that require corrosion resistance, such as in construction, machinery, and automotive industries. The white zinc plating ensures that the weld nut will remain functional and resistant to wear, even when exposed to moisture and chemicals.

Applications

Compared with carbon steel, stainless steel fasteners have the characteristics of high temperature resistance and corrosion resistance, stainless steel is also more widely used in our life, what are the advantages of stainless steel in the end?

The first point, high temperature resistance

Stainless steel fasteners high temperature resistance: it is because the hardness of the stainless steel fasteners itself is strong enough, after the production and processing of fasteners have a strong anti-oxidation ability, and it is also able to work properly at high temperatures, so it will not be subjected to high temperatures too much interference. If the stainless steel fasteners can be used after manufacturing at the same time before passivation, then its effect will become better.

The second point, the rate of electric Yin

Stainless steel fasteners electro-negative rate: the physical properties of stainless steel fasteners have a high electro-negative rate, so and carbon steel wire compared to stainless steel fasteners than its electro-negative rate is five times higher. After testing, we concluded that there is a coefficient of expansion in the fastener, if the temperature is higher, then the expansion coefficient of stainless steel fasteners will gradually increase with the temperature.

The third point, force capacity

Stainless steel fasteners stress capacity: for stainless steel fasteners, its stress capacity to carry the load is medium, even if it can not be comparable with high strength bolts, but the stress capacity of stainless steel fasteners can also meet the daily needs of people.

The fourth point, mechanical properties

Mechanical properties of stainless steel fasteners: in the mechanical properties, most of us have learnt that many of the mechanical properties of fasteners have a great relationship with the stainless steel wire. For example: will not rust, high corrosion resistance, etc., these are with the nature of the stainless steel material itself has a great relationship, with the continuous development of fasteners, these mechanical properties have become stronger.

High corrosion resistance: 316 stainless steel contains molybdenum, which can show better corrosion resistance in chloride environment, so it is widely used in marine, chemical, pharmaceutical and other fields. Good high temperature resistance: 316 stainless steel high temperature strength and oxidation resistance are better than 304 stainless steel, can maintain stable performance in high temperature environment. Good mechanical properties: 316 stainless steel has high strength, plasticity and toughness, suitable for manufacturing high-strength mechanical structures. Suitable for welding: 316 stainless steel has good welding performance and can be processed by various welding methods. Disadvantages: higher price: due to the presence of molybdenum and other precious metal elements, 316 stainless steel price is relatively high. Processing difficulty: 316 stainless steel hardness is relatively high, processing is more difficult, need to use higher cutting force and cutting speed. Higher environmental requirements: 316 stainless steel in the manufacturing process requires the use of higher purity gas and water, requiring a clean and dust-free production environment.
