Description
Machining Process
The stainless steel eye bolt is forged as a whole, and normalized and descaled; Forging/forgeable piece without over-burning, or crack defects; The hardness test of stainless steel eye bolt is HRB67~95.
The grade strength of stainless steel eye bolts produced by Yijin Hardware eye bolts suppliers is 12.9. A stainless steel eye bolt must be installed vertically on the workpiece plane, and the joint surface must be flat and tight.
It must be adjusted to the stretching direction to avoid contact between screws and sharp objects. Through the test, the load of the stainless steel eye bolts is 2.5 times the working load, and 20,000 fatigue tests are conducted under 1.5 times the working load.
Stainless steel eye bolts shall meet or exceed ASME B30.26 requirements. Our Stainless steel eye bolts are made of alloy steel which references to the German RUD WBG type, which is exported to Europe and America in large quantities and has passed the local G80 standard inspection.
We adopt better material, higher tension than existing domestic Stainless steel eye bolts, and provide tensile test reports. The Eyebolt screws should be operated by professionals, and please refer to the instructions.
When connecting with the spreader, the connecting part of the spreader and the Stainless steel eye bolts should rotate freely, and regular safety testing should be conducted by professionals.
Stainless steel eye bolts maximum working load of up to 30T and can be custom-inch thread. This kind of Stainless steel eye bolt adopts surface plating blue zinc treatment.
Blue Zinc Knowledge Expansion
The difference between blue zinc-plated and blue white zinc-plated:
Appearance and colour: Blue zinc-plated is blue, blue white zinc-plated is silver.
Corrosion resistance: The corrosion resistance of blue zinc plated is greater than that of blue-white zinc plated.
Blue-white zinc plating is electric galvanizing, electric galvanizing was originally white, being blue after blue plating, which is called blue-white zinc plating.
Compared with other metals, it is a kind of relatively cheap and easy to plating metal, and it is a low-value corrosion resistance electroplating, which is widely used to protect steel parts, especially to prevent atmospheric corrosion, and used for decoration.
Prevent iron from rusting, can be plated on the surface of the iron with a thin layer of zinc, according to the requirements can be blue and white zinc, can also be black zinc, color zinc, etc., this is based on the principle of electric conductor in the solution will absorb the atoms in the solution.
Color galvanized passivation film is used for industrial parts, and colorless galvanized passivation film is used in daily hardware, building hardware and other products requiring a white even surface.
The color depth of galvanized passivation film is also related to the thickness of the film layer. And the film thickness is related to the passivation time or the length of time in the air.
In low chrome and ultra-low chromium passivation solutions, a passivation film is formed in the solution, and if the passivation time is long, the film is thick, and vice versa, if the passivation time is short, the film is thin.
High-quality passivation film should be complete with bright colors. The reddish-brown film layer is relatively loose, and the binding force with the zinc layer is not good enough; Green passivation film may have a thin film layer, which may affect corrosion resistance.
Therefore, we can judge the quality of the passivated film from the appearance of the passivated film, the binding force with the zinc layer, the integrity of the film, brightness and color of the film layer.
