Molybdenum (Mo) metal is silvery white, very hard, but softer and more ductile than tungsten. It has a high elastic modulus, and only tungsten and tantalum, of the more readily available metals, have higher melting points. Molybdenum is added to stainless steel to increase resistance to pitting and crevice corrosion resistance, particularly in marine and acidic environments. 304 stainless steel contains no molybdenum while 316 stainless steel requires a molybdenum content of 2-3% which improves its resistance to chloride corrosion.

Molybdenum is a metal added to 316 stainless steel, sharply increasing its corrosion resistance to chlorides and sulfates especially various sulfurous acids in the pulp industry. Molybdenum helps reduce hardness and increase tensile strength at higher temperatures.

A gray metal or black powder. Used as an alloying agent in steels and cast iron, pigments for printing inks, paints, and ceramics and hair dye. Essential for life. Hazard: Flammable in form of dust or powder. Acute exposures may include severe gastrointestinal irritation with diarrhea, coma, and death from heart failure.

A hard white metallic element (symbol Mo; atomic number 42; atomic mass 95.94) which forms hard steel and/or chromium alloys to make piston rings and bicycle frames. See moly.

A brittle silver-grey metal used in some alloy steels.

Molybdenum increases hardenability of steels and helps maintain a specified hardenability. It increases high temperature tensile and creep strengths. Molybdenum hardened steels require higher tempering temperatures for softening purposes.

a polyvalent metallic element that resembles chromium and tungsten in its properties; used to strengthen and harden steel

A silvery white, very hard metal; element number 42 [Mo].

An alloy metal obtained from the ore mineral molybdenite.

An element often found in porphyry deposits. It is used extensively as an additive to steels.

A metallic element added to steel which goes into solid solution and also forms carbides. Molybdenum effectively increases the strength of steel at elevated temperatures and reduces the susceptibility to temper brittleness in chromium steels. It also retards graphitization in steels designed for service at elevated temperatures. In stainless steels it improves resistance to certain types of corrosive media.

An element added to steel to improve hardenability, tensile strength and resistance to corrosion and pitting.

An element (Mo), usually in the form of molybdenite, primarily used in alloys and lubricants.

An alloying element that enhances corrosion resistance along with chromium in stainless steels.

Its use as an alloying element in steel increases hardenability and in low alloy steels reduces the risk of temper brittleness. When added to stainless steels it increases their resistance to corrosion. It is also used in high speed steels.

a naturally occurring trace element mined for use primarily in hardening steel and cast iron. In and of itself, molybdenum is not a toxic substance. The environmental concern is how it is mined, where it is mined, and the subsequent effects on the communities in which it is mined.

An element (Mo) used in some steel alloys to add hardness and strength.

Its use as an alloying element in steel increase hardenability and in low alloy steels reduces the risk of temper brittleness. It is used in stainless steels as well as high speed steels. Chemical symbol for Nitrogen

A silvery gray, relatively rare metal with a high melting point (4,730°F, or 2,610°C) that does not occur uncombined in nature. Since molybdenum and its alloys have useful strength at temperatures that melt most other metals and alloys, they are used in high-temperature steels.

A metal used widely in alloying of other metals. It is used as hardening element for steel, and for diecasting dies. The melting point is 2,620°C (4,748°F), and the atomic number is 42.

(Chemical symbol Mo) Element No. 42 of the peridic system; atomic weight 95.95. Hard, tough metal of grayish-white color, becoming very ductile and malleable when properly treated at high temperatures; melting point 4748 (degrees) F.; boiling point about 6600 (degrees) F.; specific gravity 10.2 . Pure molybdenum can best be obtained as a black powder, by reduction of molybdenum trioxide or ammonium molybdate with hydrogen. From this powder, ductile sheet and wire are made by powder metallurgy techniques; these are used in radio and related work. Its principal functions as an alloy in steel making: (1) Raises grain-coarsening temperature of austenite. (2) Deepens hardening. (3) Counteracts tendency toward temperbrittleness. (4) Raises hot and creep strength, red hardness. (5) Enhances corrosion resistance in stainless steel. (6) Forms abrasion-resisting particles.

Molybdenum (IPA: , from the Greek meaning "leadlike"), is a chemical element. Its symbol is Mo and its atomic number 42.

Molybdenum is a trace mineral necessary for the metabolism of sulfur compounds. Organ meats, whole grains, legumes.

Good to know: Deficiency and toxicity are rare in the U.S. Recommendations: Safe and adequate amounts for ages 11-51+: 75-250 micrograms/day. Benefits: Part of many body enzymes Food sources: Milk, legumes, liver, unrefined cereals and grain products. Day's supply in: Usually attained in the course of a healthy diet. Watch out: No Warnings

An essential mineral. It is a key component of at least three enzymes: xanthine oxidase, aldehyde oxidase and sulfite oxidase. These enzymes are involved with carbohydrate metabolism, fat oxidation and urine metabolism. The average adult has about nine milligrams of molybdenum concentrated mostly in the liver, kidney, adrenal glands, bones and skin. Molybdenum deficiencies are associated with esophageal cancer, sexual impotency and tooth decay.

Molybdenum is an essential trace mineral in animal and human nutrition. It is found in several tissues of the human body and is required for the activity of some enzymes that are involved in catabolism, including the catabolism of purines and the sulfur amino acids. Molybdenum is a transition metal with atomic number 42 and an atomic weight of 95.94 daltons. Its symbol is Mo. Compounds of molybdenum are among the scarcer constituents of the earth's crust. In fact, molybdenum is only about three times more abundant than gold. The principal ore of molybdenum is molybdenite (molybdenum disulfide). Organic forms of molybdenum are found in living matter, from bacteria to animals, including humans.

Trace element that assists in the metabolism of iron in the liver, as well as being a co-factor in many enzyme systems.

A Metabolic mineral necessary in mobilizing enzymes. New research is showing anti-cancer benefits.

Molybdenum is a trace element which asists in the take-up of nitrogen. Deficiency in tomatoes and lettuce can lead to chlorosis in older leaves, necrosis and infolding of the leaves. In brassicas, leaves develop whiptail (which describes the shape of the leaves).
