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. Proper management of phosphorus can significantly improve performance across various steel applications.

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

Steels commonly used in the power generation industry have a finite life and are subject to the phenomena known as creep.
The materials are designed to possess specific properties to withstand loads at high temperatures over a defined period of time by creating an extremely stable microstructure that can cope with relatively extreme thermal exposure.

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.
