gcr15 (spheroidizing heat treatment process) metallographic diagram
Introduction
gcr15 steel is a carbon-chromium bearing steel widely used in bearing manufacturing and machine component manufacturing, and is often heat treated for improved strength and wear resistance. Through the process of hardening, quenching, and tempering, gcr15 steel components can be grea......
gcr15SiMn (1100℃×20min+470℃×2s water cooling) metallographic diagram
Heat treatment of gcr15SiMn steel is a special process that helps to improve the performance of steel components. Heat treatment is the process of using heat to correct physical properties of a metal such as material strength, hardness, ductility and formability. gcr15SiMn steel is used in many ap......
Non-metallic inclusions in gcr15SiMn steel
Abstract
The gcr15SiMn steel is a kind of low carbon steel – chromium bearing steel grade. It has been widely used in the production of mechanical components due to its good mechanical performance and wear resistance. It is well known that the nonmetallic inclusions in the gcr15SiMn steel have g......
gcr15 Fracture and Related Cracks
Introduction
A fracture is the term used for a broken part or break. This can be in the form of a crack or any other type of significant structural deformity in a material which does not necessarily break it apart into two or more separate pieces. There are various types of fracture in materials,......
Metallographic diagram of gcr15 steel (930℃ solid boronizing for 4h)
？
This paper studies the microstructural characteristics of medium-carbon bearing steel gcr15 (930℃ solid-state boronizing 4h). It was found that the quenching hardness is higher than HRC 60. The microstructure consists of grains and martensite, and a small amount of borides. It has good wear res......

Analysis of Fracture of AISI52100 Bearing Steel (Annealed After Quenching at 150°C)
Introduction
The AISI 52100 bearing steel is a type of high carbon alloy steel which contains around 1.2 per cent carbon. It is mainly used for the production of bearings and high precision machine components ......
Non-metallic inclusions in gcr15 steel
gcr15 Steel and Non-Metallic Inclusions
gcr15 steel, also known as 70CrMo, is a high-carbon chromium-bearing steel used for applications such as bearings and gears. It is a low alloy steel with good wear resistance and strength, as well as a high level of hardenability. The great majority of GCr1......
