The key difference between austenitic and martensitic stainless steel is that the crystal structure of austenitic stainless steel is a face-centred cubic structure, whereas the crystal structure of martensitic stainless steel is a body-centred cubic structure. There are four major groups of stainless steel according to the crystal structure of the steel: austenitic, ferritic, martensitic […]

The key difference between galvanized and hot dip galvanized is that most galvanized materials have a smooth and sharp finishing, whereas hot sip galvanized structures have a rough finishing. Galvanization is a process of preventing metal surfaces from corrosion. After the completion of galvanization, we say that the surface is “galvanized” if it is done […]

The key difference between low alloy steel and high alloy steel is that low alloy steels have less than 0.2% alloying element, whereas high alloy steels have more than 5% alloying element. An alloy is a mixture of two or more elements. It is produced from mixing metal with some other elements (metals or nonmetals […]

The key difference between mild steel and high tensile steel is that high tensile steel has a high strength than mild steel. Mild steel and high tensile steel are two types of carbon steel. Carbon steel contains up to 2.1% carbon by weight. Mild steel contains a comparatively low amount of carbon by weight. On […]

The key difference between natural rubber and vulcanized rubber is that the natural rubber is thermoplastic, whereas the vulcanized rubber is a thermoset. Natural rubber is the rubber material we obtain as latex from rubber trees. The raw latex is not that much of use since it has less desirable properties. To enhance its properties, […]

The key difference between Inconel and Monel is that Inconel is a nickel–chromium-based alloy, whereas Monel is a nickel-copper based alloy. Inconel and Monel are common tradenames in industry. They are two groups of superalloys which have alloys with extreme corrosion resistance. However, both types are highly expensive as well. It is because of their […]

The key difference between Freon and refrigerant is that Freon is a tradename that refers to halocarbon products, whereas refrigerant refers to a substance or a mixture used in the refrigeration cycle. Freon is a tradename which typically includes halocarbon refrigerants that leads to ozone depletion. Moreover, some Freon compounds are useful as aerosol propellants. […]

The key difference between Hastelloy and stainless steel is that Hastelloy shows an outstanding corrosion resistance compared to stainless steel. Alloys are mixtures of different chemical elements, including metals as the major component and nonmetals as a minor component. Hastelloy and stainless steel are two such alloys which are well known for their excellent corrosion […]

The key difference between ethanol and bioethanol is that ethanol is an organic compound derived from either a chemical routine or a biological routine whereas bioethanol is a form of ethanol which forms from the biological routine of ethanol production. Ethanol or ethyl alcohol (the same compound found in alcoholic beverages) is useful as a […]

The key difference between electropolishing and passivation is that electropolishing gives a superior finish and removes discolouration that passivation would leave behind. Electropolishing is an electrochemical process that removes material from a metallic surface in order to reduce surface roughness while passivation is the process of coating a surface of a metal in order to […]
