More recently a modified stainless steels have been used to produce various structural elements that work in complex operating conditions. Stainless steel X8CrNiS18-9 (standard EN 10088-3: 2005) is the most commonly used austenitic stainless steel due to its good machinability. This steel has high mechanical and working properties thanks to a compl...

Metallurgical coke, as a fuel and a reducing agent, also allows for the gas to go through a charge in the blast furnace. The coke must have a strength, porosity, reactivity and a uniform granulation, because reaction of CO2 at high temperatures in the furnace. There are various mathematical models for the optimization of coal blend, which allow the...

Steels for screws, nuts and rivets are usually low carbon steels, carbon steels or quenched and tempered low alloy steels. From these are required precisely defined strength properties, hardness and toughness, which determine the so called class strength of screws. This paper describes the thermal treatment of hexagonal screws with s...
