AISI P20 Steel vs. DIN 1.2311 Steel:- Overview
AISI P20 (commonly known as DIN 1.2311) is a versatile chromium-molybdenum alloy steel renowned for its machinability, toughness, and polishability.
It is pre-hardened to 28-34 HRC, making it ideal for molds, dies, and tooling.
Key Features
High Hardness:- Retains strength under stress.
Excellent Machinability:- Reduces production time.
Good Wear Resistance:- Ideal for high-wear applications.
Chemical Composition of AISI P20 / DIN 1.2311 Steel
The superior properties of AISI P20 Steel stem from its balanced composition:-
| Element | Percentage |
| Carbon (C) | 0.28-0.40% |
| Chromium (Cr)| 1.40-2.00% |
| Manganese (Mn)| 0.60-1.00% |
| Molybdenum (Mo)| 0.30-0.55% |
| Silicon (Si) | 0.20-0.80% |
This composition ensures high hardenability, thermal stability, and resistance to deformation.
