Material selection and product - Steel Construction

Steel material is supplied in two product forms flat products (steel plate and strip) and long products (rolled sections,either open beams,angles,etc or hollow sections).For structural use in bridges these products are inevitably cut (to size and shape) and welded,one component to another.In the structure,the material is subject to tensile and compressive forces.Mechanical properties and microstructural features ofquenched-and-tempered steel depends strongly on its microstructure.Thus,the study of effects of the mi-crostructure and dislocation structure of a steel on its strength,ductility and fracture characteristics is of great importance from the viewpoint of both theory and practice.Although AISI 4340 steel is aMetallic grain structures and microscopic analysis insight The spherical form results in improved strength in comparison to lamellar cast iron,but the hardness of the material is lower due to the lack of cementite in the purely ferritic matrix.Image taken with ZEISS Smartzoom 5,at approx.500x magnification.Fig.5 Ferritic steel with approx.0.1 % C,etched with Nital.

Metallurgy Matters Making steels stronger

As we get into modifying a steel's strength and hardness,keep a couple things in mind.First,don't confuse hardness with hardenability.A steel's maximum hardness is a function of its carbon content more carbon,more hardness.Hardenability,on the other hand,refers to the amount of martensite that forms in the microstructure during cooling.Second,low-hardenability steels require rapid cooling toMild Steel - All You Need to Know FractoryThe following are some of the common steel grades.A common denominator for all of them and other similar metals is their universal nature.Their properties make them a popular choice for a wide range of applications.EN 1.0301.Equivalent grades AISI 1008; C10; DC01.EN 1.0301 carbon steel contains 0.1% carbon,0.4% manganese and 0.4 percent Mild Steel vs Medium vs High-carbon Steel - Comparison The 10xx series (e.g.1095 steel) is the most popular choice for carbon steel used in knives as well as katanas.AISI 1095 carbon steel is brittle,and has high hardness and strength.1095 steel,when used in knives,holds a great edge and is very easy to sharpen.However,the properties of this type of steel give it a tendency to easily rust
