Ruukki's Optim portfolio of high-strength structural steels has been expanded with yet another new Optim grade. The new Optim 700 QL1 is a structural steel with improved impact strength properties. The impact strength of Optim 700 QL1 has been tested at a temperature of -60oC making it ideal for use in very demanding conditions and at sub-zero temperatures. Applications include cranes, load-bearing structures as well as frame structures and components of heavy machinery.

"The strength and impact toughness of Optim 700 QL1 structural steel ensures the load-bearing capacity of even the most demanding lifting equipment and meets the applicable safety criteria also at low temperatures," says Josu Piña, Vice President, Americas at Ruukki.

Ruukki is a leader in the development of high-strength special steels and has been manufacturing Optim high-strength steels since 2002. Ruukki's manufacturing programme includes the thinnest ultra-high-strength structural steels on the market. The new Optim 700 QL1 steel complies with the EN 10025-6+A1 standard. The steel is available in a thickness range of 6.00 - 60.00 mm. Processing of Optim steels is easy thanks to good formability, bendability, and weldability.

Ruukki also provides local technical and application support to help customers to get the most out of using special steels. Prompt and reliable deliveries are guaranteed by an extensive distribution and dealer network across some 30 countries.

DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and...

Companies are harnessing data in ways we once associated with science fiction. Analysts have access to a plethora of visualization and reporting tools, but considering the vast amount of data businesses collect and limitations of CPUs, end users are forced to design their structures and systems with limitations. Until now. As the cloud toolkit to analyze data has evolved, GPUs have stepped in to massively parallel SQL, visualization and machine learning.
"Evatronix provides design services to companies that need to integrate the IoT technology in their products but they don't necessarily have the expertise, knowledge and design team to do so," explained Adam Morawiec, VP of Business Development at Evatronix, in this SYS-CON.tv interview at @ThingsExpo, held Oct 31 – Nov 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA.
To get the most out of their data, successful companies are not focusing on queries and data lakes, they are actively integrating analytics into their operations with a data-first application development approach. Real-time adjustments to improve revenues, reduce costs, or mitigate risk rely on applications that minimize latency on a variety of data sources. In his session at @BigDataExpo, Jack Norris, Senior Vice President, Data and Applications at MapR Technologies, reviewed best practices to ...
Widespread fragmentation is stalling the growth of the IIoT and making it difficult for partners to work together.

Large industrial manufacturing organizations are adopting the agile principles of cloud software companies. The industrial manufacturing development process has not scaled over time.

Enterprises are adopting Kubernetes to accelerate the development and the delivery of cloud-native applications. However, sharing a Kubernetes cluster between members of the same team can be challenging. And, sharing clusters across multiple teams is even harder. Kubernetes offers several constructs to help implement segmentation and isolation. However, these primitives can be complex to understand and apply. As a result, it’s becoming common for enterprises to end up with several clusters. Thi...
