H and knurling of the sprocket wheels in combination with heat treatment by high-frequency-current heating leads to the formation of a fine-disperse structure of the martensite and its decomposition products during self-tempering; this contributes to a 15–20% increase in the mechanical properties....
Medium-carbon steelsare needed most when the structure or products require higher mechanical properties. Here, the range of carbon and manganese are respectively 0.30%–0.55% C and 0.60%–1.65%. They are often compared with low carbon steels. The increment in mechanical properties, section thicknes...
When we refer to a material as a medium-carbon steel, it's actually more of a term that includes all types of alloys that fall under its umbrella. There are several variations that differ in carbon content, but are all considered medium-carbon steels: 1. 4140 Steel One of Xometry's mos...
The world of carbon steels can be challenging to wrap your head around. There are many different options to choose from, and each type ofsteelhas different benefits.The main differentiating factor is the amount of carbon that is mixed with iron during production.Other materials, mainly metals, ...
The bending properties of a new thermomechanically processed medium-carbon (0.40 wt% C) low-alloy steel, intended for the slurry transportation pipeline application, have been investigated. The studied material was hot-rolled to 10 mm thick strips followed by direct quenching to two different quench...
In response to the growing interest of the automotive industry in warm precision forging, a laboratory study has been conducted to examine the response of selected medium carbon steels to warm working in the range 650–1060°C. The microstructure and tensile and impact properties have been determin...

3.Influence of surface nanocrystallization on running-in and wearing properties ofmedium carbon steel;表面纳米化中碳钢磨合磨损性能研究 英文短句/例句 1.Of course I know. according to the amount of the carbon content, carbon steels can be divided into low-carbon steel, medium-carbon steel and high...
The aim of the present study is to evaluate the influence of nano-sized carbides upon tensile behavior in UFG medium-carbon steels and to develop a material with improved tensile properties. UFG medium-carbon steels with fine carbides were successfully fabricated by multi-pass caliber rolling at ...
Studies have been made of the effect of silicate and alumina inclusions on the machining characteristics of these steels. Although silicates are detrimental in low-carbon free-cutting steels, the higher temperatures generated in cutting medium-carbon grades soften these inclusions, and there is little...
