304 Stainless Steel versus 409 Stainless Steel
304 is an austenitic stainless steel high in chromium and nickel with very high corrosion resistance. It is one of the most commonly produced and used stainless steel grades. 409 is a ferritic stainless steel with less chromium and very little nickel. It less expensive to produce than 304, but
Stainless Steel Production and Processing
We have manufactured steel for a thousand years, but stainless steel is a relative newcomer. It was invented in 1913 by a Harry Brearley, a British metallurgist. Chemists, engineers, and materials scientists have been experimenting ever since. As a rust-resistant alloy, it can offer the same material properties as steel
A Complete Guide to Stainless Steel
In this guide: How is stainless steel made? What is stainless steel made of? Types of stainless steel Stainless steel grades Mechanical properties of stainless steel A technical look – stainless steel’s molecular microstructure Care and maintenance Stainless steel is the common name for a large group of ferrous alloys
Austenitic Stainless Steel
Stainless steel is called “stainless” because of its resistance to rust. Steel contains iron and carbon in certain percentages: adding the element chromium transforms it from steel to stainless steel. Starting with these three basic elements, metallurgists have created a huge range of stainless steels. Types of metals in the
Steel Pipe: An Introduction
Steel pipes are cylindrical tubes made from steel that are used many ways in manufacturing and infrastructure. They’re the most utilized product made by the the steel industry. The primary use of pipe is in the transport of liquid or gas underground—including oil, gas, and water. However, pipes of varying
Ductile Iron vs. Cast Iron
When choosing an iron alloy for a casting, a metallurgist considers the budget, required mechanical properties, and post-casting steps like machining and heat treatment. These requirements decide what alloy to use. These days, the biggest choice is between ductile iron vs. cast iron. Technically, “cast iron” suggests iron alloys that
Globalization of Production
Reliance Foundry’s history spans the rise and fall of manufacturing in the West. From boom times through the 1920s, to decline during the globalization of production, the business of metal casting is closely tied to larger economic trends. The 1995 book “Fire in the Blood” is a detailed look at
Stages of Rust
As a material that satisfies tough, industrial requirements and offers appealing aesthetics, metal is used for products everywhere. Metals boast resilience and strength in heavy-duty applications and hardscape supplies. In infrastructure, metal can be styled in versatile ways to blend in with both the traditional and contemporary. When high-quality new
What Small Municipalities Can Learn from New York’s Street Furniture
The atmosphere of a location is built by a thousand small details. Some of this comes down to geography: the quality of light, plants in the ecosystem, and movement of air make their imprint even in the heart of a city. Cities also construct personality with the materials and design
Business Success: Saved through Innovation
Neither Brent nor Brad Done saw themselves becoming foundry men. Reliance Foundry had always been in their lives: the factory was a hot, smelly, dirty place that was equal parts proud family legacy and tough taskmaster. Their grandfather, Fred, had left the foundry to his children Brian and Barry. A
