What is EN9 material?
EN9 (070M55) grade steel is a medium carbon steel with good tensile strength. Although this grade is capable of through hardening by quenching and tempering , it is more commonly supplied in the untreated or normalised condition. It possesses good wear resistance, but poor weldability.
What is the composition of mild steel?
Chemical Composition
| Element | Content |
|---|---|
| Carbon, C | 0.25 – 0.290 % |
| Copper, Cu | 0.20 % |
| Iron, Fe | 98.0 % |
| Manganese, Mn | 1.03 % |
What is EN9 steel used for?
EN9 is used commonly for many general engineering applications. Typical applications include, shafts, axes, knives, bushes, crankshafts, screws, sickles, wood working drills and hammers.
What is the hardness of EN9 material?
EN9 CARBON STEEL

What is the difference between EN8 and EN9?
A. EN-9 is better, compared to EN-8, for Low Wear rate in rotating parts. C : higher carbon content results in an increase in yield strength and ultimate strength. 0.5% carbon steel giving higher tensile than EN8.
Which material is best for shaft?
The material used for shafts is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts are generally formed by hot rolling and finished to size by cold drawing or turning and grinding.
How can you tell if material is EN8?
EN8 engineering steel, also know as 080M40, is an unalloyed medium carbon steel. EN8 is a medium strength steel with good tensile strength. It is suitable for shafts, stressed pins, studs, keys etc. AISI 1040.
Is EN24 a mild steel?
EN24 steel is a kind of alloy structural steel – mechanical steel. The first is to improve the hardenability of steel, to ensure that the steel after heat treatment to obtain a good comprehensive mechanical property, with high strength and enough toughness.
What is the full form of EN8?
The term “Mild” is used to cover a wide range of specifications and forms for a variety of Steel. EN8: unalloyed medium carbon Steel (BS 970 080m40) has high strength levels compared to normal bright Mild Steel, due to thermo mechanical rolling.
What does EN stand for in steel?
The original ‘EN’ or ‘Emergency Number’ material designation was developed during the years of WW2 to aid the standardisation of steel reference specification and production of components produced from materials.
Is EN8 tool steel?
EN8 is an unalloyed medium carbon steel which is used in applications where better properties than mild steel are required but where the costs do not justify the purchase of a steel alloy.
What is EN8 R condition?
EN8: unalloyed medium carbon Steel (BS 970 080m40) has high strength levels compared to normal bright mild steel, due to thermo-mechanical rolling. EN8 is suitable for all round engineering purposes that may require a steel of greater strength. Heat Treatment.
Is EN8 magnetic?
The mechanisms of the effect of magnetic field treatment may vary depending on the magnetic properties of the material; EN8 steel is ferromagnetic, while aluminium AA2014-T6 alloy is paramagnetic.
What is the HRC of EN8?
34-35 HRC
Does EN8 steel rust?
EN8 and EN24 grades of steel are widely used in automobile sector in the form of shafts, studs, bolts, connecting rods, screws and rollers but they possess low corrosion resistance. Normalizing, oil quenching and water quenching exhibit lesser degree of corrosion resistance compared to that of annealed specimen.
