What is Monel Steel and its Features Monel is a group of nickel alloys, primarily composed of nickel (from 52 to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Monel is not a true cupronickel alloy, because monel does not contain the necessary 60% copper. Stronger than pure nickel, Monel alloys are resistant to corrosion by many aggressive agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding.[ What is Monel used for? Due to fabrication by hot- and cold-working, machining, and welding, Monel is extensively used in marine and chemical processing fields. However, the material is costly so can only be used where cheaper alternatives are not available. Usually, Monel piping is more than 3 times as expensive as compared to carbon steel pipe. Typical applications of Monel are valves and pumps; pump and propeller shafts; electrical and electronic components; crude petroleum stills, boiler fee

  What is Inconel Steel and its Features Inconel is a great example of a high-performance metal specifically formulated for some of the most rigorous applications . Since it is often more expensive and less widely used, Inconel is generally less familiar than steel or aluminum. This article will provide some basics about Inconel and provide answers to some common questions about this unique metal. What is Inconel? Inconel is the name for a group of nickel-based superalloys . The name Inconel is a registered trademark of Special Metals Corporation out of New Hartford, New York. The company acquired the name through acquisitions of previous companies that originally developed the various Inconel alloys. The first Inconel alloys were originally formulated for demanding, high-temperature environments in the middle of the 20th century. Chemical Composition of Inconel Since Inconel is a group of superalloys and not just one type of superalloy, its chemical composition varies across the dif

  What is Super Duplex Steel and its Features Super duplex stainless steel refers to duplex steel with PREN>40, containing 25% Cr and high molybdenum (>3.5%), high nitrogen (0.22%~0.30%), the main grades are UNS S32550 (UR52N+), S32750 (SAF 2507) And S32760 (Zeron 100) were developed by companies such as French CLI, Swedish SANDVIK and British MATER+PLATT. Their deformed materials came out around 1990 and 1991, and entered the market in recent years. The composition of these three steels is similar, the difference is the content of tungsten and copper. Outlining Super Duplex Stainless Steel Super duplex stainless steel is differentiated from standard duplex grades by its significantly improved corrosion-resistant properties. It is a highly alloyed material with elevated concentrations of anti-corrosive elements such as chromium (Cr) and molybdenum (Mo). The primary super duplex stainless steel grade, S32750, comprises as much as 28.0% chromium, 3.5% molybdenum, and 8.0% nickel

  304 vs 316 Stainless Steel Grades - The Difference The most basic difference between grade 304 and grade 316 stainless steels is that 316 tends to have more nickel and a bit of molybdenum in the mix. The general mechanical properties of the two metals are mostly comparable. The increased nickel content and the inclusion of molybdenum allows for grade 316 stainless steel to have better chemical resistance than 304 stainless steel . It’s ability to resist acids and chlorides, including salt, makes grade 316 ideal for chemical processing and marine applications. However, the addition of nickel and molybdenum also makes grade 316 a more expensive alloy than stainless steel 304 per ounce of material. Additionally, the melting point of grade 304 stainless steel is a bit higher than that of grade 316 . The melting range of 316 is 2,500 °F – 2,550 °F (1,371 °C – 1,399 °C), roughly 50 to 100 degrees Fahrenheit lower than the melting point of grade 304 stainless steel . Though the stain

  What is Duplex Steel and its Features Duplex stainless steels are called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel . The picture shows the yellow austenitic phase as “islands” surrounded by the blue ferritic phase. When duplex stainless steel is melted it solidifies from the liquid phase to a completely ferritic structure. As the material cools to room temperature, about half of the ferritic grains transform to austenitic grains (“islands”). The result is a microstructure of roughly 50% austenite and 50% ferrite. Duplex stainless steel is not a modern day concept. In fact, the idea of creating duplex stainless steel goes back to the early 20th century. The first cast was manufactured in Avesta in Sweden in the year 1930. With that being said, duplex steel has rose to prominence only in the last 3 decades. The popularity that it has achieved is based on the fact that steel making techniques are being improv

  Properties And Uses Of Copper Alloy Steel Copper is a soft, tough, ductile and malleable material. These properties make copper extremely suitable for tube forming, wire drawing, spinning and deep drawing.   Copper (Cu) provides interesting alloying advantages to steel and steel welds. Cu (atomic no. 29 and atomic weight 63.54) has a density of 8.96 gm/cc. The melting point of Cu is 1083 deg C while the boiling point is 2570 deg C. Cu is normally added to steel to increase corrosion resistance. Experimentation with the addition of Cu to structural steels for its ability to impart good atmospheric corrosion resistance properties began in the year 1916 in the USA. The first commercial use of Cu bearing steel as atmospheric corrosion resistant steel was during the period 1933 to 1935 . Cu is beneficial to atmospheric corrosion resistance when present in amounts exceeding 0.20 %. The atmospheric corrosion resistance steels are also called weathering steels. Uses of Copper and Coppe

  Properties And Uses Of Carbon Steel Carbon steel is steel with carbon content up to 2.1% by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: Steel is considered to be carbon steel when: no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; the specified minimum for copper does not exceed 0.40 percent; or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. The term “carbon steel” may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels. Carbon Steel Steel is one of the most commonly found and important metals for mankind. When you look around you, you will see that almost everything in your house has some element of steel in it. S
