A Simple Overview of Cracking
Why do things crack? A stress is applied that is strong enough to separate the material. Metals are theoretically much stronger than we find in practice, and this is due to “artifacts” within the microstructures that act as stress concentrators.
A Tour of the City of Hamilton’s Water and Wastewater Treatment Plant
The City of Hamilton, Ontario began treating its water in 1859. The facility started the way most water treatment plants did, as a resource for fire protection.
Understanding the Connection Between Reliability and Safety
Reliability goes beyond the technical details of industrial assets; it is a mindset. Enhancing equipment performance not only optimizes operations but also impacts human lives. The lack of reliability results in leaks, uncontrolled releases, and catastrophic equipment failures that could jeopardize the workplace. Tami Glasper, the Reliability Manager at Air Products and Chemicals, Inc. spoke to Stainless Steel World Americas and provided valuable insights into her role and the critical intersection of reliability and safety.
Comparing the Passivation Performance of Common Stainless Steels in Green Leaching Solutions for Metal...
For decades, the use of extremely toxic and environmentally detrimental cyanide in the hydrometallurgical extraction of gold has been a target of research looking for greener alternatives. One promising alternative for cyanide is non-toxic thiosulfate solutions. In fact, for carbonaceous gold ores, the recovery of gold has been shown to improve with thiosulfate solutions versus cyanide. This is attributed to the thiosulfate compound with gold not adsorbing on the carbonaceous ore, unlike that of cyanide compound with gold. In addition, hydrometallurgical leaching with thiosulfate is more economically viable versus cyanide due to the lower costs of thiosulfate salts versus that of cyanide.
Corrosion and Cracking of Stainless Steel
Stainless steel is used in multiple industries (e.g., food, medical, chemical, oil and gas) and various manufacturing processes for aesthetic purposes and high resistance to corrosion in harsh environments. There are five basic families of stainless steel: austenitic, ferritic, martensitic, duplex, and precipitation hardened. Of these, austenitic is considered the most resistant to corrosion.
