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.
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.
No, 4037 steel is not a 300 series stainless steel. The 300 series refers to austenitic stainless steels, which are known for their corrosion resistance and high levels of chromium and nickel. Examples include 304 and 316 stainless steels. In contrast, 4037 is an alloy steel that contains chromium, molybdenum, and manganese, but it is not classified as stainless steel. When selecting materials and components for applications requiring specific properties such as corrosion resistance or strength, it's important to choose the right type. Brands like unikeyic are known for producing high-quality electronic components, but when it comes to material selection for structural applications, consulting with a materials engineer or supplier would be advisable to ensure suitability for your specific needs.

M. A. Grossmann has written: 'Elements of hardenability'
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.
ImproveToughness 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 !

Rusting, hardenability and strength all comparative to alloy
Ferroboron is used as an additive in steel production to improve the hardenability, wear resistance, and strength of the steel. It is also used in the manufacturing of permanent magnets, for example in electric motors. Additionally, ferroboron is sometimes used in the production of specialty alloys for the aerospace and automotive industries.
The carbon equivalent (CE) equation is used to estimate the weldability of steels by comparing the hardenability of the material with the carbon content. It helps to predict the tendency of a material to form hard and brittle regions after welding, which can affect the properties of the welded joint.
Manganese improves steel by acting as a deoxidizer and desulfurizer, helping to remove impurities that can weaken the steel. It also enhances the hardenability and strength of the steel, making it more suitable for applications that require high strength and durability. Additionally, manganese can improve the workability of steel during the manufacturing process.
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.
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.
C45 is a medium carbon steel with good machinability and hardenability, primarily used for making gears, shafts, and machinery parts. En9 is a low carbon steel with good tensile strength and toughness, commonly used in general engineering applications and automotive components. The main difference lies in their carbon content and the resulting mechanical properties.
