Malleability is a physical property of a material that describes its ability to deform under pressure or hammering without cracking or breaking. Malleable materials can be reshaped into new forms without losing their internal structure or strength.
18/8 stainless steel is the most widely used and flexible austenitic form of stainless steel. The numbers 18/8 represent the composition of this steel; it is 18% chromium and 8% nickel, making it very resistant to corrosion and oxidation.18/8 stainless steel is also highly durable and easy to...
Shielded metal arc welding (SMAW) is a fusion welding process that uses a consumable, flux-coated electrode to create an arc between the electrode and the work piece. Molten metal travels from the electrode via the electrical arc and is deposited into the work piece. The flux coating is also melted...
Because oxide films produced by corrosion of iron are not self-healing, coatings and cathodic protection methods are generally used to protect ferrous surfaces.
It is essential to understand the advantages and disadvantages of each metal coating type to select the one that is best for your application.
By:Krystal Nanan| Civil Engineer
Commonly used to protect numerous structures such as pipelines, ships, tanks and offshore oil platforms, cathodic protection works by allowing a more reactive, sacrificial metal to corrode instead of the protected metal.

The short answer to the question is yes. Zinc does rust.Like all metals, zinc corrodes when exposed to air and moisture. However, this element does not rust like most other metals.Iron, for example, reacts with water and oxygen in the atmosphere to form hydrated iron (III) oxide on the metal's...

A corrosion rate conversion is a technique to change the measurement units of a given corrosion rate to another unit for comparison purposes or a specific engineering application. When converting a corrosion rate between these units you must keep in mind that a mil is a thousandth of an inch (i.e.,...

Glen Bishop was the Surveyor for Class Society (insurance authority) World-wide. While surveying, he saw ships with electrolysis hull damage, most frequently around the power generation area. Two hundred ships per year were being severely damaged with a high proportion of them sinking. In 1992 over a 3-week period his vessel became porous while docked in a new mooring with a steel post between each vessel. Ten years and 220 tested vessels later he found his answer.Glen has 53 years in marine electronics experience including nine years at sea with the last four years in submarines. As a young man he received his formal training at HMS Collingwood, Portsmouth, England. He then spent 45 years in marine electronics using MPLab, Protel, Multism, and many others constructing circuits.Ten years ago Glen began developing an instrument that would test if electrolysis was occurring on vessels. As regular instruments were not precise enough he created a prototype and then tested 220 vessels. The prototype was perfected and he has been clearing vessels of electrolysis ever since. His early clients were in and around Australia, and he has since expanded to a worldwide presence.Today Glen oversees his electronic engineering company, which does research and development and manufactures special marine products.
