Bollards vs. Jersey Barriers

The invention of the combustion engine unleashed great power for our use. We zip goods and people around the world more quickly than most of our ancestors could imagine possible. Yet the wonder of this freedom has come at a cost: greater forces in travel mean more severe accidents when

Ferrous and Non-Ferrous Metals

Any solid metal that can be melted can be cast. Foundries are the factories that do this casting work, developing expertise with a handful of metals and methods, and designing standard products to maximize value and efficiency in production. Metals and casting methods influence each

Introduction to Forging Methods

What is forging? Forging is a manufacturing process involving the shaping of a metal through hammering, pressing, or rolling. These compressive forces are delivered with a hammer or die. Forging is often categorized according to the temperature at which it is performed—cold, warm, or hot forging. A wide range of

Cleaning Stainless Steel

Stainless steels are highly corrosion resistant—however, stainless steel applications can still remain at risk to surface damage. Oxidation, corrosion, rusting, or staining can occur over the long-term in harsh environments without routine cleaning and maintenance. Repeat mechanical damage also contributes to a faster degradation of the metal. All stainless steels

Does Stainless Steel Rust?

Will stainless steel rust? Stainless steel is armed with built-in corrosion resistance but it can and will rust in certain conditions—although not as quickly or severely as conventional steels. Stainless steels corrode when exposed to damaging chemicals, saline, grease, moisture, or heat for prolonged periods of time. Stainless steel’s protection

304 Stainless Steel versus 316 Stainless Steel

Judging by the name, you might assume that stainless steel never stains—but you’d be wrong. Stainless steel stains less easily than other iron-based metals, but it’s not literally “stainless”. Just like standard steel, stainless can get marked up by fingerprints and grease, develop discoloration, and

Cast Iron vs Cast Steel

Casting offers exceptional capacity for design detail, often eliminating the need for additional fabrication and assembly. Many materials can be cast, including several types of metals and synthetics, but iron and steel in particular feature excellent mechanical properties for a wide range of applications. While cast iron and steel may

Hot Rolled vs Cold Rolled Steel

Steel comes in many grades, specifications, shapes, and finishes—the World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more applications. Optimizing
