Strenx 960 Uses

Strenx 960 is ideal for applications requiring high strength and durability. Some common applications of Strenx 960 include heavy-duty trucks and trailers, cranes and booms, construction equipment, and pressure vessels. It also has applications in aviation, automotive, mining, and other heavy-duty industries.

Strenx 960 Corrosion Resistance

The addition of trace amounts of copper and chromium in the composition of Strenx 960 enhances its corrosion resistance. This makes it ideal for use in harsh and corrosive environments, such as marine environments. However, you should always ensure proper maintenance and upkeep to keep the steel rust-free.

Strenx 960 Heat Treatment

Strenx 960 can be heat-treated to enhance its mechanical properties. The steel can be quenched and tempered to achieve properties such as high tensile and yield strength, high toughness, and improved endurance.

Strenx 960 Machining

Strenx 960 has excellent machinability, despite its high strength. The steel can be machined with standard tools, but if you’re working with thicker plates, it’s ideal to use carbide and ceramic tools. You can also use water-based coolants to help to reduce heat damage.

Strenx 960 Welding

Strenx 960 has excellent weldability thanks to its low carbon content. The steel can be welded with all welding techniques, including MIG, TIG, and SAW. However, it’s important to ensure that the welding process is properly designed and executed to guarantee the integrity of the joint.


Strenx 960 is a high-strength steel with a composition that makes it ideal for use in various heavy-duty applications. It has impressive mechanical and physical properties, making it one of the strongest steels available on the market. Strenx 960 also has excellent corrosion resistance, heat treatability, and machinability, which make it an ideal choice for use in challenging and harsh environments.
