Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy.

Which of the chemical element has greatest effect on hardenability of steel?
carbon
What has the author M A Grossmann written?
M. A. Grossmann has written: 'Elements of hardenability'
What is the difference between Hardness and Harden-ability of steel?
There are some differences between hardness and hardenability. Hardness is the surface property of material to give resistance to the penetration or plastic deformation and it is measured by one of the tests......Rockwell hardness test,Brinell hardness test and Vicker hardness test. On the other hand,hardenability is defined as the ability how the material would be hardened and it is measured by Jominy hardenability test.
What is the hardness of 1095 steel?
It depends on the heat treatment. 1095 has a high carbon content so it is capable of achieving high hardnesses, but only in thin sections because its low hardenability.
What are 3 limitations of Ferrous Alloys?
Rusting, hardenability and strength all comparative to alloy
What is Molybdenum- vanadium Steel?
CrMoV steel is a heat resistant steel typically used in applications such as shafts and fasteners used in high temperature service. The chromium is used in this steel to increase resistance to corrosion and oxidation, to impart high temperature strength and to increase the hardenability. The molybdenum addition also imparts higher hardenability and increases high temperature tensile and creep strengths. The vanadium addition inhibits grain growth during heat treating while improving strength and toughness. This steel is referenced in the industry specification AMS 6304.
What does the pcm value of steel mean?
The weldability of steels depends on its hardenability.In general, the higher the hardenability, the lower theweldability. Weldability can be evaluated theoretically byuse of the PCM value calculated according to:PCM = C + Si/30 + Mn/20 + Cu/20 + Ni/60+ Cr/20 + Mo/15 + V/tO + 5B.
What is difference between hardness and toughness?
Toughness is the ability of steel to absorb energy. Hardness is the ability of steels to withstand wear. Hardness is the ability of material to withstand the indent and is measured in rockwel or vickers. also it is a measure of stiffness of material. but hardenability is ability of material to become hardened by various methods of hardening such as carburising or quenching. it is firmly dependent on quantity of carbon in that material. and actually it doesn't have any measuring unit !
Alloy composition?
(1) Carbon: CRole: increase the hardness of the quenching organization; the formation of carbide, improve wear resistance; reduce toughness; reduce weldability.(2) Chromium: CrRole: improve the hardness of steel, the formation of hard and stable chromium carbide, thus improving wear resistance; can improve the hardenability of steel; when the Cr content of more than 12%, with corrosion resistance, and provide a good throw spin.

Why hardenibility is not so high in plain carbon steels?
To harden a steel, it is heated to the austenitic region and then quenched to martensite. The rate at which the steel is quenched must be rapid enough to form martensite and not other microstructures (namely bainite, pearlite, or ferrite), which are not as hard. The cooling rate is a function of composition. Adding alloying elements to steel maintains hardenability at slower cooling rates, essentially shifting the TTT diagram. TTT diagram for steel in link below.
What are nitra alloys?
Nitralloy the generic name of a group of structural steels used to manufacture nitrided parts. The main alloying elements of nitralloys are aluminum, chromium, molybdenum, and vanadium, which form fine-crystalline hard nitrides that impart a high hardness (Vickers hardness, up to 1200) and wear resistance to the nitrided surface layer. The most common nitralloys in the USSR are 38KhMIuA and 38KhIu steels. Type 38KhMIuA steel, which is used in the manufacture of critical parts, contains 0.15--0.25 percent molybdenum, in addition to aluminum and chromium. The molybdenum increases hardenability, moderately improves the ultimate strength of the core of the part, and prevents the development of temper brittleness during nitriding.
