摘要： [Problem to be Solved]To provide a novel briquetting roll having excellent performance such as providing both abrasion resistance and spalling resistance, which can also be manufactured at low cost and in a short period of time, and a method for manufacturing the same.[Means for Solving the Problem]A briquetting roll 1 integrally has an inner layer material 4 and an outer layer material 5, which comprise mutually different materials and are in contact with each other at the respective exterior and interior thereof, and has pockets 6 formed at the outer circumference of the outer layer material 5. A chromium-molybdenum forged steel material is used for the inner layer material 4 and a high-carbon high-speed steel material is used for the outer layer material 5. The outer layer material 5 may be formed on the outside of the inner layer material 4 by a continuous pouring process.

摘要： A method for cost effectively case hardening a component formed from a martensitic stainless steel material with a desired metallurgical condition for high temperature, high rolling contact fatigue, corrosion and spall initiation and propagation resistance bearing performance. The method describes a method to significantly reduce the carburization or carbo-nitriding process times for appreciable reduction in manufacturing cost. The Method includes the steps of: forming the component from a martensitic stainless steel material having an ASTM grain size of 9 or finer; and subjecting the component to one of a carburization and a carbo-nitriding treatment with significantly lower case hardening times for manufacturing cost-effectiveness.

摘要： The invention provides a rolling/sliding part that can elongate the service life and can increase the static load capacity to improve the indentation resistance to an indentation due to plastic deformation during rest and low-speed rotation. The rolling/sliding part is formed from a steel that contains C: 0.7 to 0.9% by weight and Cr: 3.2 to 5.0% by weight and has a surface layer portion of which surface is carburized. An area ratio of total precipitated carbide of the surface layer portion is set in the range of 15 to 25%. Of the total precipitated carbide present in the surface layer portion, 50% or more by area ratio of carbide is rendered a M7C3 type and/or M23C6 type. An average grain diameter and a maximum grain diameter of the surface layer portion are set in the range of 0.3 to 0.6 μm and at 4 μm, respectively. The surface hardness is set at 62 or more by Rockwell hardness C. A solid solution carbon amount in residual austenite of the surface layer portion is set in the range of 0.95 to 1.15% by weight.
