Lower Carbon

Abstract AK Steel Type 304 is a chromium-nickel austenitic stainless steel. It is a variation of the base 18-8 grade, but with higher chromium and lower carbon content. The lower carbon content minimizes carbide precipitation due to welding and reduces its susceptibility to intergranular corrosion. Type 304 is the most versatile and widely used stainless steel grade. It combines good resistance to atmospheric corrosion and to many chemicals, food, and beverages. It has excellent formability. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties as well as fatigue. It also includes information on low and high temperature performance, and corrosion resistance as well as forming and joining. Filing Code: SS-1317. Producer or source: AK Steel Corporation.

The Impact

This article is a response to the state of the art in monitoring the cooling capacity of quenching oils in industrial practice. Very often, a hardening shop requires a report with data on the cooling process for a particular quenching oil. However, the interpretation of the data can be rather difficult. The main goal of our work was to compare various criteria used for evaluating quenching oils. Those of which prove essential for operation in tempering plants would then be introduced into practice. Furthermore, the article describes monitoring the changes in the properties of a quenching oil used in a hardening shop, the effects of quenching oil temperature on its cooling capacity and the impact of the water content on certain cooling parameters of selected oils. Cooling curves were measured (including cooling rates and the time to reach relevant temperatures) according to ISO 9950. The hardening power of the oil and the area below the cooling rate curve as a function of temperature (amount of heat removed in the nose region of the Continuous cooling transformation - CCT curve) were calculated. V-values based on the work of Tamura, reflecting the steel type and its CCT curve, were calculated as well. All the data were compared against the hardness and microstructure on a section through a cylinder made of EN C35 steel cooled in the particular oil. Based on the results, criteria are recommended for assessing the suitability of a quenching oil for a specific steel grade and product size. The quenching oils used in the experiment were Houghto Quench C120, Paramo TK 22, Paramo TK 46, CS Noro MO 46 and Durixol W72.
