The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

When a natural gas or oil pipeline is under repair, it is absolutely necessary to check that the new weld is completely secure. On a fundamental level, the integrity of the weld depends on the total ...

Precipitation-hardenable (PH) stainless steels are turning up in more and more aerospace applications because they can be age hardened, sometimes after being cold worked, to various strength levels ...

Duplex stainless steels are typically known to have a dualphase microstructure that contains both ferrite and austenite grains. This so-called microstructure offers a uniquely beneficial combination ...

Compare popular steel alloys used in modern engineering. Learn where A36, 4140, 304 stainless, A572 Grade 50, and 2205 duplex ...

• AHSS steels have both high strength and good formability. • A mixture of microstructures gives AHSS their properties. • Designers should aim for structural efficiency, thin plates, and strong joints ...
