What is the difference between 20MnCr5 and 16MnCr5?
16MnCr5/20MnCr5 Steel is defined as Mn-Cr case hardening steel as per EN10084 Standard. Compared with 16MnCr5,20MnCr5 has a little higher on Carbon, Manganese, and Chromium, both of them have good hardenability, machinability, and wear resistance, but poor in weldability.
What is the chemical composition for 20MnCr5?
Heat to 650-700 oC. Temperature 900-950 oC . Cooing from carburizing temperature: water, oil, air, thermal bath, cooling box. Core hardening 850 – 880 oC….Percentage of Elements in Chemical Composition of grade 20MnCr5 steel (1.7147): EN 10084-2008.
| C | Si | Mn |
|---|---|---|
| max 0.035 | max 0.035 | 1 – 1.3 |
What does 16MnCr5 mean?
16MnCr5 is an alloyed case hardening steel used for e.g. mechanical engineering components. The steel can be M-treated in order to optimize the machinability.

What is hardness of 20MnCr5?
The 20MnCr5|1.7147 Carburizing steel will get Hardness MAX 248 HB （Brinell hardness）.
What is 20MnCr5?
20MnCr5 is a case-hardening steel with low carbon content but good hardenability reaching good wear resistance due to high surface hardness after hardening. The small grain size benefits in good ductility and fatigue strength. Suitable for gearboxes and axle gears.
Is 20MnCr5 low carbon steel?
20MnCr5 is a case-hardening steel with low carbon content but good hardenability reaching good wear resistance due to high surface hardness after hardening. The small grain size benefits in good ductility and fatigue strength.
What is 16MnCr5?
Steel grade 16MnCr5 is a structural steel for parts that are surface hardened. It is made in accordance with the BS EN ISO 683-3 standard (formerly EN 10084). Classification: Special alloy steel.
