A corrosion-resistant alloy (CRA) is an alloy consisting of metals such as: Chrome. Stainless steel. Cobalt. Nickel. Iron. Titanium. Molybdenum.
Some alloys are resistant to oxidation at the specific temperatures but increasing the limits, the protection degree reduces significantly. For example SS 321 offers sufficient performance up to 870oC or 1600of but at 980oC or 1800of, its service is inadequate, on the other hand SS 309 is suitable for use up to 1040oC or 1900of.
Chromium is the main alloy element in stainless steel, acid-resistant steel and heat-resistant steel. Chromium can improve the strength and hardness of carbon steel under rolling, reduce the elongation and shrinkage of cross-section.Machinemfg
Resistance wire can be classified as Iron Chrome Aluminum (FeCrAl), Nickel Chrome (NiCr), Copper Nickel (CuNi), and Nickel Iron (NiFe) alloys. If your application demands extremely high temperatures, an Iron Chrome Aluminum alloy may be the best choice, where as if your application requires the wire to maintain sufficient mechanical strength at temperature, Nickel Chrome may be a better option.
5 Common Alloying Elements Chromium. Chromium added to carbon steel in percentages usually greater than 11% creates stainless, element resistant alloy Molybdenum. Molybdenum, like chromium, has an effect on the corrosion resistance of steel. Vanadium. Vanadium is used to help control the grain size of the steel, , element resistant alloyMarketing
The alloy has good corrosion resistance except in sulfur containing atmospheres and certain controlled atmospheres. The high electrical resistivity, relatively low TCR, and its ease of fabrication have made this alloy widely used in "edge-wound" power resistors.
In many environments, alloy 27-7MO offers resistance approaching or exceeding that of much more highly alloyed materials such as INCONEL alloys 625, 22 and C276. Applications for this allow are found in the pollution control, power, marine, chemical processing, pulp and paper, pharmaceutical and oil and gas industries.

Molybdenum alloys. Molybdenum is used in mercury wetted reed relays, because molybdenum does not form amalgams and is therefore resistant to corrosion by liquid mercury. Molybdenum is the most commonly used of the refractory metals. Its most important use is as a strengthening alloy of steel.
environments,nickel is more corrosion resistant than iron, but not as resistantas copper. Alloying with chromium provides resistance to oxidation thus providing a broad spectrum of alloys for optimum corrosion resistance in both reducing and oxidizing environments. Nickel-based alloys have a higher tolerance for alloying elements in
An alloy is a combination of metals or a combination of one or more metals with non-metallic elements. For example, combining the metallic elements gold and copper produces red gold, gold and silver becomes white gold, and silver combined with copper produces sterling silver. Elemental iron, combined with non-metallic carbon or silicon, produces alloys called steel or silicon steel. The resulting mixture forms a substance with properties that often differ from those of the pure metals, such as i
The benefits of the low resistance and low temperature coefficient of resistance copper nickel alloy heater element are most significant when the heater is one which applies heat over large intervals of subterranean earth and at a temperature level of 600 C. to 1000 C. lntervals of 1000 feet or more can be heated with these heaters.
If Cu is added to a Ni-Cr-Mo-Fe alloy, resistance to hydrochloric, phosphoric and some concentrations of sulfuric acids is improved. Cobalt (Co) Cobalt imparts unique strengthening characteristics to high temperature alloys. Cobalt also increases the resistance in nickel alloys to carburization and sulfidation.
Although titanium and its alloys are resistant to corrosion in many media, including aqueous solutions of chlorides, stress corrosion of commercially pure titanium and of titanium alloys can take place in a limited number of highly specific environments.
In general, copper reduces the resistance to general corrosion of aluminum-zinc-magnesium alloys, but increases the resistance to stress corrosion. The minor alloy additions, such as chromium and zirconium, have a marked effect on mechanical properties and corrosion resistance.
Nickel-Chromium Heating Element and Resistance Alloys in Wire Bar Strip Ribbon. These alloys are especially characterized by high resistivity and high resistance to oxidation and chemical corrosion. They are suitable for making high-value electrical resistors, heating wires, heating cords and cables.
Elements experts test for dezincification resistance in accordance with ISO 6509, the most widely used test method for determination of dezincification resistance of copper alloys with zinc. This test has proven useful to correct alloy selection for new applications and guide corrective actions to address field failures.
Magnesium is the primary alloying agent in the 5xxx series and is one of the most effective and widely used alloying elements for aluminum. Alloys in this series possess moderate to high strength characteristics, as well as good weldablility and resistance to corrosion in the marine environment.
In addition to resistance alloys, we carry ceramics, heating racks, insulators, laboratory furnaces, plus spare parts for older units. Performance Standards. National Element Inc. stocks only top quality resistance alloy, ceramics and molybdenum to ensure manufactured parts work, last and perform to specifications.

FeCrAl Iron Chromium Heating Element and Resistance Alloys in Wire Bar Strip Ribbon forms. These are ferromagnetic alloys whose electrical resistance properties are similar to those of the Nickel-Chromium alloys, making them suitable for electrical heating applications.
High Temperature Corrosion Resistant Alloys. The 80/20 nickel chromium alloy is often used for wrought and cast parts for high temperature applications, as it has better oxidation and hot corrosion resistance compared to cheaper iron-nickel-chromium alloys. This nickel chromium alloy is highly suited to applications that are subject to oxidation.
The nickel-base alloys range in composition from commercially pure nickel to complex alloys containing many alloying elements. A distinction is usually made between those alloys that are primarily used for high-temperature strength, commonly referred to as superalloys, and those that are primarily used for corrosion resistance.

416 - Free-machining variation of 410 with useful corrosion resistance to natural food acids, basic salts, water and atmospheres. 430 - Is the most popular of the non-hardenable chromium stainless steels. It combines good corrosion and heat resistance with good mechanical properties.
The predominant metal in the alloy is called the base metal. The other metals or elements added to the alloy are called alloying elements. Examples of Alloys. In addition to increasing the strength of a metal, alloying may change other properties, including the resistance to heat, corrosion resistance, magnetic properties, or electrical , element resistant alloy
Alloying elements are added to change their properties. Stainless Steels are iron-based alloys that meet the ASTM A941 definition for this alloy family, specifically a steel that conforms to a specification that requires, by mass percent, a minimum chromium content of 10.5 or more, and a maximum carbon content of less than 1.20.
