Corrosion is defined as a refined metal that is naturally converted to a more stable form such as its hydroxide or sulphide state. Metal corrodes when it reacts with another substance such as oxygen, hydrogen or bacteria. Corrosion can also happen when metals are placed under too much stress causing the material to crack. Corrosion leads to deterioration of the material.
Stainless steel is highly corrosion resistant, making it suitable for use in environments where exposure to moisture, chemicals, or harsh conditions such as salt water is expected.
In this section you can find newsitems related to all types of corrosion such as stress corrosion cracking, intergranular corrosion, pitting, and corrosion fatigue. If you wish to include your news release on our website and email newsletter, please feel free to contact the editor.
MMFX® Steel Corporation of America introduced their latest line of high-strength reinforcing steel featuring a 100 ksi yield strength, ChromX™ 4100. This product is targeted at large construction projects in need of high-yield strength at a reasonable material cost.
MMFX Steel Corporation of America appointed Arthur Sakaev as a new regional sales manager. Sakaev will lead activities in the Southwestern U.S., including California, Nevada, Utah, Arizona and Hawaii.

Outokumpu continues to bring new innovations to market and is now expanding its product range with two new high-chromium stainless steel grades, ferritic grade EN 1.4622 and austenitic grade EN 1.4420.
JFE Steel Corporation, together with Marubeni-Itochu Steel, has supplied natural resource developer Freeport-McMoRan Oil & Gas with 1,900 tons of JFE-UHP-15CR-125 heavy-walled casing produced at JFE Steel’s Chita works.
Baosteel has developed 80kg-grade easy-welding high-strength steel that realizes no-pre-heating welding. Baosteel has started the supply of the product in batches to customers.
Easy-welding high-strength steel is used in manufacturing of mechanical equipment used in coalmines, especially for making hydraulic support, which requires corrosion resistance, wear resistance, shock resistance, high strength, lightweight and easy processing.
The Nickel Institute released a new report that highlights nickel’s contributions to technologies for a more sustainable society and economy, to meet the needs of a growing global population.
Nickel’s versatility and robustness make it an ideal material to provide solutions for energy, transport, food and clean water as well as to meet other key sustainability challenges.
Chu Kong Petroleum and Natural Gas Steel Pipe Holdings Group has received accreditation from reputable industry experts for its newly developed clad pipe (Clad pipe). The Clad pipes have qualified API 5LD (2009), DNV OS F101 (2005) and clad pipes technical specification requirements after an examination by the National Quality Supervision and Inspection Center Oil Pipe and CNPC Tubular Goods Research Institute.
Essar Steel, one of India’s largest integrated steel producers, launched high-quality, colour-coated products, specially developed for the Kerala market. These specialised steel products will largely be used in the housing and industrial resorts segment in the region.
Outokumpu will provide stainless steel for the façade on Ping An Finance Center in Shenzhen, China. The skyscraper’s façade will be the largest stainless steel façade in the world.
Corrosion can be a big problem because it can cause significant damage and deterioration to various materials, particularly metals. We have listed below several reasons why corrosion is a significant concern:
Structural Integrity: Corrosion weakens the structural integrity of materials. When metals corrode, they lose their strength and load-bearing capacity, which can lead to failures and collapses in infrastructure, buildings, bridges, pipelines, and other critical structures.
Economic Impact: Corrosion imposes substantial economic costs. The direct expenses associated with corrosion include repairs, replacements, and maintenance of corroded structures and equipment. Additionally, there are indirect costs such as production losses, decreased efficiency, and increased energy consumption due to the effects of corrosion on industrial processes and machinery.
Environmental Consequences: Corrosion can have adverse environmental effects. For example, in the case of pipelines, corrosion can lead to leaks and spills of hazardous substances, causing soil and water pollution and damaging ecosystems.
Health and Safety Risks: Corrosion can create health and safety risks in various ways. For instance, when corrosion affects pipelines or storage tanks carrying toxic substances, it can lead to leaks or releases that endanger the health of workers, communities, and the environment.
Maintenance and Downtime: Corrosion necessitates regular maintenance and inspection programs to detect and mitigate its effects. This requires significant time, effort, and financial resources. Additionally, when corrosion-related issues arise, it often requires shutting down operations, causing downtime and productivity losses.
Given these reasons, it is crucial to understand and address corrosion through preventive measures, protective coatings, corrosion-resistant materials, regular inspections and testing (ASTM B117), and appropriate maintenance practices to mitigate its impact and ensure the longevity and safety of structures and equipment.
