Effect of Phosphorus on the Properties of Carbon Steels: Part Two
This article examines the impact of phosphorus on the texture (R-value), spot weldability, magnetic properties, and coating behavior of carbon steels. Phosphorus enhances deep drawability and strength while influencing weld characteristics and reducing core loss in electrical applications. Research demonstrates that phosphorus additions up to 0.1% can significantly improve steel performance when properly managed.
Fe-Ni-Mn Maraging Steels: Part One
Maraging steels are a special class of low‐carbon ultra‐high‐strength steels which are produced by precisely controlling the amounts of nickel and manganese in the finished material.Depending on the variation in these two important elements it is possible to make gains in various key characteristics of the finished product including superior hardness properties.
Fe-Ni-Mn Maraging Steels: Part Two
Maraging steels are a special class of low‐carbon ultra‐high‐strength steels which are produced by precisely controlling the amounts of nickel and manganese in the finished material.The maraging response is highly dependent on the manganese content and at precise levels can produce profound hardness visible through classical age hardening curves as a function of aging temperature and time.
Ferritic Creep Resistant Steel: Part One
Ferritic creep resistant steels serve as essential materials in power generation applications, designed to withstand sustained loads at temperatures up to 600-700°C over operational lifetimes of 20-30 years. These specialized steels combat time-dependent deformation (creep) through carefully engineered microstructures containing stable alloy carbides and solid solution strengthening elements.
Ferritic Creep Resistant Steel: Part Two
Steels commonly used in the power generation industry have a finite life and are subject to the phenomena known as creep.Chromium and tungsten have been studied to assess their potential to improve creep life and overall results were positive where optimum inclusion of Cr and W results in much improved creep rupture strength.
From the History of Iron and Steel Making: Part One
The Voelklingen Ironworks was founded in 1883 and developed into one of the leading iron and steel works in Germany and Europe. The singular compactness of the ironworks blast-furnace unit with six blast furnaces and the inclined elevators for transporting iron ore and coke, unparalleled in the world, form a skyline that has made a lasting impression on the German Saar valley for more than 100 years.After its closure in 1986, it was declared as a historical monument, and in 1994 was awarded the status of a World Cultural Heritage by UNESCO. Today, Voelklingen Ironworks is the only plant worldwide surviving in its original form from the heyday of iron and steel industry.
