How to choose a high-quality hoist ring?

A hoist Ring is a lifting tool and lifting ring. As a lifting equipment, it is widely used in various industrial fields. Hoist Ring has hoisting capabilities. Compared with traditional lifting eye screws, Hoist Ring can provide greater load-bearing capacity and lifting effect.

Hoist Ring Strength Grade

Hoist Ring bolt strength grades mainly include two standards: 8.8 and 12.9. With the rapid development of the mold industry, rotating lifting rings have been widely promoted and applied. The main service targets include mold factories, factories, machinery factories, and other fields. At the same time, the emerging wind power industry has an even more urgent demand for rotating lifting rings.

Material Selection

In terms of material selection, 35CrMo alloy steel, and 42CrMo alloy steel are commonly used, while imported materials usually use nickel-chromium-molybdenum alloy steel or grade 100 materials.

Why Choose These Two Materials

The composition of 35CrMo alloy steel mainly includes elements such as iron, chromium, and carbon, and contains a certain proportion of manganese, silicon, phosphorus, etc. The precise ratio of these elements makes 35CrMo alloy steel outstanding in terms of strength, toughness, and wear resistance.

In terms of mechanical properties, 35CrMo alloy steel has high tensile strength and yield strength, as well as good toughness, plasticity, and wear resistance. It has outstanding impact absorption capabilities and can effectively cope with various stresses and impacts. In addition, 35CrMo alloy steel has good hardenability and can meet the requirements of different working conditions through heat treatment. Its heat treatment process is simple and easy, including annealing, normalizing, quenching, and tempering, to adjust its mechanical properties.

42CrMo alloy steel is a high-strength, high-toughness low-alloy steel material. Compared with 35CrMo alloy steel, it has a higher carbon content and contains appropriate amounts of chromium, nickel, and other elements, giving it superior strength and toughness. In terms of mechanical properties, the tensile strength and yield strength of 42CrMo alloy steel are higher than that of 35CrMo alloy steel. Its impact toughness is also more outstanding and can better cope with various complex stresses and impacts. In addition, 42CrMo alloy steel also has excellent wear resistance and corrosion resistance and can be used for a long time in harsh working environments.

Why Not Choose Other Materials

Regarding the selection of other materials, because their performance is inferior to 35CrMo alloy steel and 42CrMo alloy steel in terms of strength, toughness, and wear resistance, they are not given priority.

Surface Treatment

In terms of surface treatment, methods such as plastic spraying, spray painting, and galvanizing are often used. These surface treatment technologies were chosen not only for their excellent protective effects but also because they can significantly enhance the overall quality and market competitiveness of the product.

Surface Treatment Classification

Plastic Spray Treatment

Plastic spraying is a process in which plastic powder is electrostatically adsorbed to the metal surface and baked and solidified at high temperatures to form a uniform coating. This method not only enhances the corrosion resistance of the Hoist Ring and prevents the metal from being directly exposed to the external environment, but also greatly improves the durability of its appearance, texture, and color. Suitable for applications with high requirements on aesthetics and durability.

Spray Paint Treatment

Spray painting is a more traditional surface treatment method, which can form a protective film on the surface of the Hoist Ring to prevent oxidation and reduce wear. By choosing different types of paint, different anti-corrosion effects and aesthetic needs can be achieved. In addition, spray paint can also be customized in a variety of colors according to customer needs to adapt to different use environments and aesthetic requirements.

Galvanized Treatment

Galvanizing prevents iron parts from rusting by covering the surface of the lifting ring with a layer of zinc. The zinc layer can sacrifice itself to protect the base metal. Even if the zinc layer is destroyed, it can still slow down the corrosion rate of the base through electrochemical protection. This method is particularly suitable for use outdoors or in other highly corrosive environments, effectively extending the service life of the Hoist Ring.
