Tensile strength is the ability of a material to withstand a pulling (tensile) force and refers to the breaking strength of a material when applying a force capable of breaking many strands of the material simultaneously, at a constant rate of extension/load. It is customarily measured in units of...
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...
Grinding is an abrasive machining process that uses a grinding wheel or grinder as the cutting tool. Grinding is a subset of cutting, as grinding is a true metal-cutting process. Grinding is very common in mineral processing plants and the cement industry.Grinding is used to finish workpieces that...
Corrosion resistance and wear resistance are important factors, but equally significant is the strength of the material. Here are six common ways to measure a material's strength during material selection.
Several factors, such as anticipated traffic, environmental conditions, and durability requirements must be taken into consideration to determine the best floor coating for the given application.

The short 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 surface of the...

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.
A past board member of NACE, Ron Bianchetti has 38 years of professional experience in corrosion engineering design, project management, and construction management. His industry experience includes oil and gas pipelines, water/wastewater facilities, power generation facilities, offshore facilities, and reinforced and pre-stressed concrete structures.
Ted Huck is an electrical engineer and cathodic protection expert with over 25 years of experience in technical sales. He has authored over a dozen articles in a wide range of publications, and is a frequent presenter at corrosion conferences in the United States and internationally.
