Metallographic diagram of ZG30CrNiMo (normalized, quenched, tempered)
The microstructure of AISI4140 ZG30CrNiMo alloy steel under normalizing, tempering, and annealing treatments is characterized through optical microscopy and scanning electron microscopy. The results show that when normalizing and tempering, the microstructure of AISI4140 ZG30CrNiMo alloy steel con......

Metallographic Examination of Heat Treated Hydrochloric Acid-Pickled High-Chromium Iron Castings
High-chromium iron castings are used in a variety of applications, such as valve bodies and pump casings, due to their superior wear resistance, impact and corrosion resistance. To further improve the......
35CrMo steel (pit cooling after forging) low microstructure and non-metallic inclusions
Abstract
35CrMo steel is a high-strength alloy steel that is widely used in the forging and heat-treatment industry. It exhibits excellent mechanical properties, making it a popular material for applications such as construction, manufacturing, and automotive components. This paper gives an overv......
Metallographic diagram of 40Cr (1100℃×20min+500℃×4s water cooling)
The microstructure of AISI 40Cr steel after being heat treated at 1100°C for 20 min followed by oil quenching is relatively complex. The structure consists of upper and lower layers of martensite, a bainite/pearlite band in between them, carbide precipitation on the ferrite/austenite grain bounda......

Ferritic Steels and Their Applications
Ferritic steels are a type of steel alloy that are commonly used in many everyday applications. Ferritic steels contain between 10.5 and 27 % chromium along with relatively low amounts of carbon and other alloying elements such as nickel, manganese, and mol......
45Mn2 (1100℃×20min+450℃×20s water cooling) metallographic diagram
Microstructure of 45Mn2 Steel After Heat Treatment
Heat treatment is often used to alter the microstructure of a material. By changing the temperature, time, and cooling rate of a heat treatment, the desired microstructure and strength of material can be achieved. 45Mn2 steel is commonly used for......
Metallographic structure of low carbon carbon steel of pure iron, 10 steel, 20 steel (annealed state)
Different types of materials have different microstructures. From the point of view of steel, it can be divided into low carbon steel, medium carbon steel and high carbon steel. The microstructure of low carbon steel can be divided into three types: pure iron, 10 steel and 20 steel (annealed state......
Metallographic diagram of 15 steel (annealed state)
Fig 1.0 is a metallographic cross-sectional optical microscopy image of a 15 steel sample in an annealed condition. The sample was extracted from an industrial size bar using a standard cutting technique and mounted for examination using a standard light microscopy methodology with oil-immersion. ......
Metallographic structure of 20 steel (tempered at 1800°C) low carbon carbon steel
Introduction
Low carbon steels are an important part of the metals industry and are widely used in the construction, automotive and other industries. There are many types and categories of low-carbon steel, including UNS G1020 steel.
UNS G1020 steel is a type of low carbon steel that has a high ......
