corrosion resistance is resistant against chemicals oxidation resisstance is restant against oxigen
State of Hg in Hg2Cl2 is 1
There is not much difference in both of them
Ferrous metals contain iron, which is prone to rusting through the process of oxidation, leading to the formation of iron oxide (rust). Non-ferrous metals, such as aluminum and copper, do not contain iron and therefore do not rust. Instead, they undergo different types of corrosion, such as oxidation or patina formation.
Yes, there is a difference between HCR (High Carbon Steel) and HCRM (High Carbon-High Chromium Steel). HCR typically contains a higher percentage of carbon, making it harder and more wear-resistant, while HCRM includes chromium, which enhances corrosion resistance and improves toughness. This makes HCRM suitable for applications requiring both hardness and resistance to oxidation. Overall, the addition of chromium in HCRM tailored its properties for specific industrial uses.
Corrosion is a chemical oxidative process. Erosion is a physical wear process.
Without getting technical on this, the simple answer is Hastelloy C-276 is a wrought material. Hastelloy is also a trademarked name for the material by Haynes International. CW12MW is an (almost) equivalent material in a cast form. Either sand or investment cast. There is a slight chemistry difference between the two, but for most industrial applications either works for corrosion resistance. Some companies call it Alloy-C.
SS316, SS304, and SS316L are all types of stainless steel. SS316 is known for its increased corrosion resistance compared to SS304, particularly in high chloride environments. SS316L is a low carbon version of SS316, which helps prevent sensitization and subsequent corrosion.
A105 is a carbon steel typically used for forged fittings and flanges in high-temperature applications, while 304 is a stainless steel known for its excellent corrosion resistance and formability. A105 has a lower tensile strength and is more prone to rusting, making it suitable for non-corrosive environments. In contrast, 304 is more versatile due to its resistance to oxidation and is often used in food processing and chemical industries.
dry corrosion is taken place in the presence of gases whereas wet corrosion takes place in the presence of moisture in air
304 and 304L are stainless steel electrodes. but in 304L, L denotes Lower percentage of Carbon content.It improves the corrosion resistance character of filler wire.
corrosion of metals is a chemical reaction between metal and oxygen in atmosphere. Oxidation of metals called corrosion. It affects the physical properties of metal in either way like rusting, colour change, life cycle shortening etc.
SS 321 contains titanium which makes it more corrosion resistant than SS 304. SS 321 is better suited for high temperature applications due to its improved resistance to intergranular corrosion. SS 304 is a general-purpose stainless steel with good overall corrosion resistance but not as high as SS 321.
