Fig. 2. Typical oxide found in SAE steel austenitized at °F and salt quenched (X, 2% Nital, oblique illumination) Steel cleanliness has become a topic of great interest to the heat treater given the reality that steel is a global-sourced commodity. Often, the type and distribution of inclusions have a significant influence on mechanical properties. Theoretical and Practical Considerations of Sheet Steel Surface Cleanliness Paint failure on cold-rolled sheet steel occurs by cathodic delamination of the paint film. Steel exposed at discontinuities in the paint coating becomes the anode of an electrochemical corrosion cell, and adjacent areas under the paint become the cathode of that Cited by: 8.

Download the AIST Ladle and Secondary Refining award winning paper written by Eugene Pretorius, Helmut Oltmann, and Brian Schart from Nucor Steel. This paper will focus on how individual and combined analysis techniques are applied in a steel production environment to assess steel cleanliness and to measure the effect of process variables on steel cleanliness.

The definition of ‘clean steel’ varies with steel grade and its end use, as shown in Table II. Table II Steel cleanliness requirements for various steel grades. However, despite the major advances in inclusion control, no rapid and accurate method is available to determine the type, size, and number of inclusions present in steel samples.
RJ Lee Group, Inc., with AMO and steel industry support, has developed the ASCAT, an inclusion analysis tool based on a highly capable scanning electron microscope. For decades, inclusions have been associated with the general problem of fatigue failure in steels.
For steel applications where high fatigue strength under dynamic loading is required such as for bearings, crankshafts and gears, the main focus in production is the control of inclusion characteristics.Non-metallic inclusions reduce the fatigue strength and by: Jim Shaw, EVP of Engineering at Crystal Group, discusses the importance of cleanliness in the production process.

ABSTRACT： The progress in control technology of carbon, nitrogen, total oxygen, phosphorus, and sulphur as well as inclusions in steel is made at Baosteel.
The increasing demand for excellent steel properties has led to the creation of new steel grades such as high manganese TWIP and TRIP steels which are scientifically examined in Germany within the international research framework of the SFB “Steel-ab initio.” The production of these high-technology products, utilizing mainly the ingot-casting method, leads to new challenges in the Cited by: 8.

This paper aims to provide useful information for the production of clean steel, focusing on the control of. Clean steel technology refers to the use of improved manufacturing technology to produce steels with reduced impurities, improved reliability, and a more homogeneous metallurgical structure.
To ensure steel cleanliness and homogeneity, comparative analyses are used to address inclusion type, morphology, distribution, and elemental by: 2.teel cleanliness has become a topic of great interest to the heat treater given the reality that steel is a global-sourced commodity.
