High Strength chains are made from heat-treated carbon steel

High Strength Chains
High Strength chains are links with high tensile strength, used for hauling and drawing loads. They are usually made of broad metal links. There are many different types of High Strength chains. Learn about them, and find one that's right for your needs. Choosing the right type of High Strength chain is critical to your business's success.
High Strength chains are manufactured to meet ANSI standards and are available in three styles. Each has unique properties to increase its strength and reduce wear. These chains are produced using innovative manufacturing processes that make them the best in the industry. They feature through-hardened pins and after heat-treated ballized link plates for increased fatigue strength and wear resistance.
High Strength chains are available in various grades, which indicate their tensile strength in N/mm. Chains in the highest grade have higher breaking strength than those with lower grades. For example, a grade 30 chain has less carbon than a grade 40 chain. This makes it a good choice for service duty applications.
High Strength chains are made from heat-treated carbon steel. They are ideal for heavy towing and securing. High Strength chains are also popular for overhead lifting. They also come in gold chromate finish, making them easy to identify for DOT officials. These chains are also the most economical option available. They are commonly used in construction, manufacturing, and rigging applications.
When purchasing High Strength chains, remember to choose one that is rated for the weight of the load. It's crucial to select the right one, because a poor rated chain can cause severe injuries or even death. Inspecting the chains before you buy is very important because you don't want to make a costly mistake and end up ripping them apart.
There are three main types of High Strength chains available in the market. The first is the Grade 80 chain. It is the most popular type of chain for overhead lifting applications. Despite its name, it's made of tempered alloy steel, which makes it more resistant to extreme heat. It has a strength to weight ratio of up to 25 percent, making it the perfect choice for any overhead lifting application.
High Strength chains come in stainless steel and alloy steel. These materials have higher tensile strength and are also more corrosion-resistant. In general, stainless steel chains range from 375 pounds to 23,000 pounds. For general-purpose use, the highest-grade chain is the Grade 30 chain, while the Grade 43 chain is the next toughest type. These chains are not for overhead lifting, but they are still strong enough to handle heavier loads.
Flash butt welding is the common welding process for large-diameter steel chains. However, it's inefficient due to its high cycle time and produces low-quality welds. Further, the heat-treated material used in flash butt welding requires expensive quality control. Therefore, engineers developed a new welding process.
