Iron and Steel Vander Voort

TOOL STEELS can be prepared for macroscopic and microscopic examination using the same basic procedures used for carbon and alloys steels. However, because many tool steels are highly alloyed and are generally heat treated to much higher hardness than most carbon and alloy steels, specific aspects of their preparation differ slightly. Metallographic Specimen Preparation - KemetMaterial:50 CrV4 Low alloy steel. Results:The existence of alloy carbides is due ro 1.1% chromium. Very thin carbide particles can be seen in the tempered martensitic matrix in the microstructure. Below given preparation method gives very good scratchfree surface. Etching:3% Nital Metallographic Specimen Procedures and Guidelines for Metallographic Preparation Guidelines. Metallographic specimen preparation requires knowledge of the specimen properties, the most important characteristics are the hardness and ductility of the metallographic specimen.

Metallography and Microstructures of Carbon and Low-Alloy

This article describes the microstructure and metallographic practices used for medium- to high-carbon steels as well as for low-alloy steels. It explains the microstructural constituents of plain carbon and low-alloy steels, including ferrite, pearlite, and cementite. Metallography and Microstructures of Stainless Steels Metallographic preparation is more successful, and easier, if an abrasive cutoff wheel designed for metallo-graphic work with stainless steels is used. Figure 1 illustrates the damage that results when an aus-tenitic stainless steel is sectioned using different procedures. Figure 2 shows sectioning damage in a 26Cr-1Mo ferritic stainless steel. Metallography of SteelsIn some steels containing a strong carbide-forming elements such as Mo or V, tempering at temperatures where these solutes are mobile leads to the precipitation of alloy carbides (Fig. 31).

Metallographic preparation of stainless steel. The majority of stainless steels are soft and prone to deformation and scratching during metallographic preparation, which makes an accurate preparation method essential. Find out how to prepare stainless steel for metallographic examination with reproducible results. Download the full application note Mirror surface machining of high-alloy steels by Jul 01, 2017 · Recently, industrial demands for mirror surface machining of high hardness steels such as cold work die steels or high-speed tool steels (hereinafter called high-alloy steels) are increasing. The high-alloy steels, whose Rockwell C hardness exceeds 60 HRC, are used in forging processes as well as injection molding processes. Preparing Tool Steels for Microstructural ExaminationThis article discusses the metallographic preparation of tool steels. Preparation Procedures 400, and 600-grit. When carbide pullout is an issue, finer grit sizes can be utilized for high-alloy tool steels. Grinding pressure can be moderate to heavy, and the grinding process can be proceed for 1 to 2min for removing scratches and

Mar 15, 2012 · The etchant most widely used for tool steels is nital. Etchants useful with tool steels are listed in Table 1. Concentrations from 2 to 10% have been used. Generally, 2 or 3% nital is adequate for most tool steels while a 10% concentration is required for highly alloyed tool steels, such as the D Standard Specication for Tool Steels Alloy1molybdenum high speed tool steels (Note 1) and have charac-teristics similar to the tungsten types. NOTE 1High-speed tool steels are covered in Specication A 600. 3.1.2 Cold Work Tool Steels, Identication ATypes A2 to A10 cover a wide range of carbon and alloy contents but all have high hardenability and may be hardened in air.
