What are the mechanical properties of medium carbon steel?
Mechanical Properties
| Mechanical Properties | Metric | Imperial |
|---|---|---|
| Hardness, Vickers (Converted from Brinell hardness) | 170 | 170 |
| Tensile Strength, Ultimate | 565 MPa | 81900 psi |
| Tensile Strength, Yield | 310 MPa | 45000 psi |
| Elongation at Break (in 50 mm) | 16.0 % | 16.0 % |
What is the effect of carbon on the mechanical properties of steel?
In addition to brittleness, yield point, tensile strength and rusting are all affected by increased carbon concentration. Increasing carbon also reduces the weldability, especially above ~0.25% carbon. Plasticity and ductility are similar. Think of a blacksmith, where he’s hammering on a knife blade.
What is CK45?
AISI 1045 Carbon Steel G10450 \ Din CK45 W-Nr. This grade of steel is used for axles, bolts, forged connecting rods, crankshafts, torsion bars, light gears, guide rods etc .
Is standard for forging?
5.1 All forgings shall be manufactured from killed steel produced by the open hearth, electric, basic-oxygen or any other suitable method which will meet the requirements of this standard. 5.2 The raw material for the production of carbon steel forgings shall be in accordance with IS 1875 : 1991.
What is the properties of medium carbon steel?
Types of carbon steel and their properties
| Carbon content (wt.%) | Properties | |
|---|---|---|
| Medium-carbon steel | 0.25 – 0.60 | Low hardenability, medium strength, ductility and toughness |
| High-carbon steel | 0.60 – 1.25 | High hardness, strength, low ductility |
What is a medium carbon steel?
Medium-carbon steels are similar to low-carbon steels except that they contain carbon from 0.30% to 0.60% and manganese from 0.60% to 1.65%. These steels are mainly used for making shafts, axles, gears, crankshafts, couplings, and forgings.
How does carbon increase hardness of steel?
As the carbon content increases, the proportion of cementite in the steel also increases. Since the cementite is relatively hard, the hardness of the steel increases accordingly. Since more cementite is precipitated with increasing carbon content, the fraction of fine lamellar pearlite structure also increases.
How does carbon increase the strength of steel?
The use of carbon makes iron — or steel — stronger by shuffling around its crystal latice. While carbon steel can still stress and break under pressure, it’s less likely to occur than with other types of steel.
Is standard for carbon steel?
This standard covers the requirements for carbon steel castings for general engineering purposes. The Indian Standards listed in Annex A are necessary adjuncts to this standard. General requirements relating to supply of steel castings shall be as laid down in IS 8800.
