AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. Annealing ASTM 4130 alloy steel offers excellent ductility. AISI 4130 steel is usually supplied as round bar commonly in the hardened and tempered condition.
AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications. AISI 4140 steel gives greater strength and heat treatment capabilities in comparison.
AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. AISI 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed.
Incoloy alloys have more iron contents than inconel alloys. These alloys show outstanding corrosion resistance, strength, durability, and high-temperature stability.
Monel refers to a group of nickel alloys that have copper as the main alloying element. In addition to these two primary metals, Monel alloys may also contain small amounts of iron, manganese, carbon, silicon, sulfur, aluminum, and titanium. The specific composition of a Monel alloy depends on its desired properties and applications. In general, Monel alloys are known for their high strength and resistance to corrosion in both fresh and saltwater while also having excellent high and low-temperature resistance.
Inconel alloys are high-performance nickel/chromium superalloys developed for high temperatures, corrosive environments, and oxidation resistance. They are used in the harshest environments such as: in chemical processing reaction chambers/valves, polymer granule manufacture, military applications, gas turbine components, oil fields, and high-grade marine applications.
Inconel alloys include:
Inconel 600: solid solution reinforcement
Inconel601
Inconel 625: Acid resistance, good weldability. The LCF version is commonly used for bellows.
Inconel 690: Low cobalt content and low resistivity for nuclear applications
Inconel 713C: Precipitation-hardened nickel-chromium base cast alloy Inconel
718: Gamma double prime reinforced with good weldability
Inconel 751: Increased aluminum content to increase fracture strength in the 1600 °F range
Inconel 792: Increased aluminum content to improve high-temperature corrosion performance, especially for gas turbines
Inconel 939: Gamma prime reinforced to improve weldability
Hastelloy is a kind of nickel based alloy. Hastelloy Alloy can be divided into two groups; one contains more molybdenum and the other contains more chromium. They all have excellent resistance to strong oxidizing solutions and high durability in reducing agents. Because of the low carbon content and less carbide precipitation during welding, they also have the ability to resist intergranular corrosion.
Incoloy alloys are known for their iron content. Nickel, iron, and chromium are the main and vital ingredients for Incoloy alloys.
The term nickel alloy refers to a metal that has nickel as one of its primary elements. Some types of nickel alloys are referred to as superalloys because of their superior oxidation and creep resistance, allowing them to be used at temperatures of more than half their melting points. Nickel alloys can be machined and welded but tend to pose some processing difficulties, as some alloys will work harden during machining, and their high melting points can make them difficult to weld.
