For questions related to the alloy steel: Its production, material properties and applications. The carbon content of steel is between 0.002% and 2.1% by weight for plain iron-carbon alloys.

The shear force required should depend upon the shear area: $$N \pi \biggl(\frac{5}{16}''\biggr) \biggl(\frac{7}{16}''\biggr)$$ or number times circumference times height, since the side-walls of $N …

Assume you have a sample of some material, in this case steel, and want to apply a load for an extended period of time, sufficiently long for noticeable relaxation to occur. The load is not sufficient … before relaxation proceeds, all $\varepsilon_{0}$ is recovered and the steel material returns to its original shape. If instead the material experiences the load sufficiently long so that relaxation …

There is a method for plating stainless steel with an Fe-25Ni-16Cr alloy which uses electroplating. The results from the article give a maximal electroplated layer thickness of 23 um. The properties … of the electroplated alloy seem to be of similar quality to their reference sample of SAE 316 stainless steel. Electroplating stainless steel onto substrates is challenging specifically due to the …

. Plain-carbon steel with no other alloying additions should have ferrite density very close to that of pure iron, or about $7870\:\textrm{kg}/\textrm{m}^3$ (from Google), and cementite has a theoretical … maximum carbon concentration in a steel, by definition, is close to 2.14 weight percent, whereas in cementite is 6.67 weight percent. So the volume-weighted density would be a minimum of approximately …

strength. The test does not specify composition, only that the material is plain carbon-steel. BSEN10149 is a British standard grading for steel alloys evidently, and some grades together with mechanical … properties are noted on a commercial site, though none of the grades meet the properties you are looking for. The American Society for Metals has a useful article on HSLA steel grades and associated …

process name. It is worth noting these processing methods are somewhat different from traditional tempering and aging. Different enough to warrant a special name. First a bit of background. When a steel is … with the iron. If the steel is quenched rapidly enough and to a low enough temperature, a speed-of-sound diffusionless process occurs where the dissolved carbon is trapped in the iron BCC lattice …

Stating categorically that bamboo is stronger than steel is a bit like stating that automobiles are faster than planes. On its face, it is a bit shocking, and seems wrong. But a rocket-powered … include ecological factors (bamboo is renewable), environmental factors (bamboo is flammable), loading factors (steel can be made ductile and its high properties are isotropic), and weight considerations …

Summary: The Fe-C system, and thus steel, is unique due to a eutectoid transformation from a high-solubility phase to a low solubility phase that allows for a wide variety of microstructures and … , and ferrite has low carbon solubility. I am picking on first-row transition metals as they tend to have chemical behavior "close" to that of steel, with similar cost, density, and other "obvious …

You are not exactly right. The purpose of Cr and Ni in stainless steel, besides the stainless part, is to tailor the microstructure. Cr promotes ferrite, Ni promotes austenite. Other elements have … course if you want austenite, you can't simply load up the steel with carbon or it will become extremely brittle and hard to work with. The fact that different elements have different efficiencies is what …

copper wiring, or tin-coated steel cans. Antimony and arsenic tend to creep in from low-quality and low-cost primary iron sources. The answer to the question is no. Recycled steel is mixed as evenly as … specific steel grade for a specific product or application. Stainless steels and other high-alloy grades which are known at recycling time are processed separately due to the value of Ni, Cr, etc. It is …
