M3 M4 M6 M8 Weld Nut Carbon Steel Grade 4.8 8.8 12.9 Weld Hexagon Nut Black Oxide Coating
Product Description:
Weld nut meets the specific strength needs of different industries, from automotive manufacturing to heavy machinery assembly.
One of the key features of this product is its black oxide coating, which offers enhanced corrosion resistance and a sleek, professional appearance. The black oxide finish also provides some degree of lubrication, making it easier to assemble and disassemble the parts. This coating is particularly useful in environments where the weld nut will be exposed to moisture or chemicals, as it helps protect the nut from rust and wear over time.
In addition to the corrosion resistance, the black oxide coating also improves the weld nut’s overall aesthetic, giving it a polished look that is suitable for applications where the visual appeal of the components matters, such as in exposed mechanical assemblies or automotive products.
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.
