Elemental Analysis of Metal Powders and Metal Parts Produced by Additive Manufacturing

Introduction An integral part of industrial product development is the manufacture of prototypes and initial samples, regardless whether the product is a simple screw or the complex part of an airplane. To fabricate single pieces, which are often rather small, in a production environment is usually a costly procedure. Based on this cost-benefit calculation a special application field of powder metallurgy has developed in the past few years: additive manufacturing. Additive manufacturing (AM) is the “process of joining materials to make objects from 3D model data.”1 AM creates objects layer upon layer from different metal powders or metal alloy powders.

Carbon & Sulfur Determination in Steel Plants and Foundries with ELTRA’s ELEMENTRAC CS-i Analyzer

IntroductionSteel plants observe the decreasing carbon content during the whole steel production process from raw iron with up to 4-5 % carbon to a few ppm in stainless steel. The carbon content influences not only the texture, but also the material properties of iron, such as magnetism, hardness or elasticity. For example, cast iron (2-4 % C) is brittle but castable; tool steel (0.4-1,7 % C) is elastic and ductile, carbon steel (< 0.4 % C) is forgeable and useable for sheets, tubes and steel girders (1). The element carbon can be present in different forms in an iron matrix,

Effective Quality Control of Steel and Iron Products with Combustion Analysis

 Introduction The element concentration of carbon (C), sulfur (S), hydrogen (H), nitrogen (N), and oxygen (O) in iron products, such as steel, have a significant influence on material properties like ductility, brittleness, or hardness. Hence, reliable determination of the C, H, N, S, O contents is a routine quality control task in steel and iron production. This article explores the application fields and advantages of elemental analyzers, which are also known as combustion analyzers, in the steel industry.  Different analytical methods  A great variety of different analytical methods are used in steel and iron production1. Disregarding analyses of physical parameters,

The development of the first carbon and sulfur analyzer in 1981 marked the beginning of ELTRA’s success story 40 years ago. From day one, the focus was on the design of analyzers for the precise determination of C, H, N, O, S element concentrations in solids. Over the years, the product portfolio was further expanded and refined, for example by adding thermogravimetric analyzers in 2007. Our goal has always been to design combustion analyzers which are characterized not only by high precision and detection sensitivity but are also robust enough to provide reliable measurement results under rough conditions. The new

With the ELEMENTRAC ONH-p 2, ELTRA presents a powerful and robust elemental analyzer for measuring oxygen, nitrogen and hydrogen concentrations in inorganic samples such as steel, iron, copper or ceramics. The high-detection NDIR and thermal detectors reliably measure elemental concentrations from low ppm levels to the high percentage range. Thanks to the innovative sample lock with pulsed chamber flushing and vertical sample drop, user-friendly and convenient analysis of rod-shaped, granular or powdered samples with a sample weight of up to 2 grams is easily possible. The analyzer can be configured for the determination of only one element (O, N or
