Example: A mining company achieved improved machine lifespan and profitability with superior wear-resistant steel plates.

As a result of trying various brands, the one that clearly demonstrated superior performance was SSAB's Hardox(R) 550/600!

Asia's leading open-pit copper mine, the Dexing Copper Mine, was searching for more durable wear-resistant steel plates for its hopper liner plates. **Challenges** - The hopper liner plates wear out quickly due to the harsh daily operations. - Replacing the plates takes two weeks, and maintenance is not easy. - Frequent replacements lead to increased workload and downtime. ~Adoption of Hardox® wear-resistant steel plates~ 1. Hardox® 550/600 was used on the sides and bottom of 18 ore extraction machines. 2. The lifespan of the liner plates has been extended by 2 to 3 times. 3. Maintenance frequency has decreased, and the plate replacement frequency has improved to every two years. 4. The use of thinner wear-resistant steel plates has reduced engine load. By adopting SSAB's Hardox® 550/600, work efficiency has increased, leading to higher production and increased revenue. *For more details, please contact us or download the PDF document to view.*

Example: Gjerstad takes a step ahead with design and Hardox(R)

Example: Gjerstad takes a step ahead with design and Hardox(R)

The steel plate and new design have met our company's and customers' expectations in every aspect!

Norwegian excavator bucket manufacturer Gjerstad decided to improve the performance of its products just over a year ago. Gjerstad is known for using a wide range of SSAB steel plates. For over 20 years, the company has supplied steel plates for bucket wear parts. [Gjerstad's Wishes] - Emphasis on important financial aspects for customers - Being more than just a sticker that meets customer expectations - Reduction of maintenance costs - A completely new design - Valuable support ~By using Hardox(R)500, far ahead of competitors~ 1. Manufacturing lighter buckets by switching from Hardox(R)450 to Hardox(R)500 2. Lighter and stronger than buckets of the same size = reduced fuel consumption 3. This experience has led to a noticeable reduction in maintenance costs 4. A comprehensive redesign has improved performance Since SSAB operates in all regions where Gjerstad outsources manufacturing, it has been easy to arrange visits to manufacturing sites and on-site seminars. *For more details, please contact us or download the PDF materials.

Example: Blades made of Hardox® wear-resistant steel are active in a sugar factory.

Example: Blades made of Hardox® wear-resistant steel are active in a sugar factory.

By switching the blade material to Hardox(R)500, we achieve improved efficiency.

The knife used to cut the fibrous stalks before crushing the hard sugarcane in a large press needed to withstand the acid-like juice of the sugarcane. Only robust and wear-resistant blades can achieve this. **Challenges at the Ingenio de Atencingo sugar factory in Mexico:** - Short knife lifespan - Time-consuming knife maintenance - Resulting unnecessary downtime ~Switching the blade material to Hardox(R)500~ 1. Knife lifespan increased threefold 2. Reduced maintenance time 3. Avoidance of unnecessary downtime 4. Improved final results By changing the material of the cutting knife previously used to Hardox(R)500, Ingenio de Atencingo was able to enhance efficiency and ultimately improve final results. *For more details, please contact us or download the PDF materials to learn more.*
