What Is Low Alloy Steel?

Robb Edwards — Thu, 27 Apr 2023 17:47:59 +0000

What Is Low Alloy Steel? In general, there are two categories of steel: Low alloy steel has low percentages of alloying elements such as chromium and nickel compared to stainless steel. As a result, low alloy steel does not have the heat, wear, or corrosion resistance provided by stainless steel. However, low alloy steel provides…

Metal Casting Inspection Methods: What They Tell and What the Limitations Are

Dave Olsen — Wed, 12 Oct 2022 16:14:37 +0000

Metal casting is precise and process orientated. With countless variables potentially affecting the result, casting inspection procedures must be rigorous. Inspection methods can vary between casting type, and different inspection methods are often used for a single casting. More than anything else, metal casting inspections provide customers with confidence that they received a quality casting. …

Ferrous vs. Non-Ferrous Metals

Robb Edwards — Mon, 19 Sep 2022 16:30:38 +0000

From skyscrapers to naval propulsion systems, from automotive parts to petrochemical furnace tubes, there is no shortage of real-world applications for metal. Metals come in a wide range of structures, properties, and applications but are commonly organized into two categories: ferrous metals and non-ferrous metals. Below we explain the definitions, common types, differences, and popular…

Heat Treatment for Metals

Robb Edwards — Tue, 24 May 2022 15:39:23 +0000

What is Heat Treatment? Heat treatment is a thermal process that accomplishes three primary improvements to the material properties of metal castings: Improving mechanical properties Enhancing corrosion resistance Reducing residual stresses The heat treatment process begins with heating the metal casting to the desired temperature before cooling the metal in a controlled way to achieve…

What Is Pitting Resistance Equivalency Number (PREn)?

admin — Tue, 01 Dec 2020 20:47:32 +0000

The Pitting Resistance Equivalency Number (PREn) is an objective way to do an initial comparison of the relative resistance to corrosion of various metals. It is based on a calculation that considers the weight percentage of alloying elements. Pren Number Formula: PREn = % Cr + (3.3 x % Mo) + (30 x % N)…

Examples of Continuous Castings Solving a Problem and Decreasing Costs

admin — Tue, 01 Dec 2020 03:28:27 +0000

The continuous casting process involves pouring molten metal through a die of the desired outside profile. If shaping on the I.D. is also desired, the material may flow around a mandrel to create that profile. As a result, continuous cast product is often chosen to dramatically reduce machining cost. Here are just two examples of…

10 Examples of Choosing the Right Metal Alloy for the Application | Alloy Metal

admin — Tue, 01 Dec 2020 02:00:12 +0000

Sometimes particular alloys work in an application. Sometimes critical components and materials just don’t perform in a certain environment at all. There are factors like strength, resistance to corrosion, environmental temperature extremes, and many others, that help dictate which alloy metal to choose. Often a designer will select a familiar standard “workhorse” grade and keep…

Why Certain Metals Offer Greater Wear Resistance

admin — Tue, 01 Dec 2020 01:37:44 +0000

One regularly hears recommendations about material selection. Use this alloy for superior heat resistance. Or that for seawater corrosion. Or this other one for a high wear application. But what about the alloy actually makes it deliver that performance? In this installment, we will explore some simplified technical reasons – at the microscopic level –…

Material Applications: High-Temperature Corrosion

admin — Thu, 26 Nov 2020 03:37:58 +0000

The Effect of Temperature on Corrosion of Metals As the performance demands on metals tend to increase as temperature increases, so do the types of corrosive attacks to which the metal is likely to be subjected. When we think of significant industries and applications that are most likely to face the combined effects of high…
