STEEL ALLOYS-CASE-HARDENING STEELS

16 MnCr5(1.7131) Steel

16 MnCr5(1.7131) is a low-alloy steel known for its good hardenability, strength, and wear resistance. This steel is commonly used in applications that require components with a combination of these properties. The numerical composition “16MnCr5” indicates its alloying elements and approximate composition:

16 stands for the approximate carbon content (0.16%).

Mn represents manganese as a major alloying element.

Cr represents chromium as an alloying element.

5 signifies the approximate carbon content (0.5%) of chromium.

16MnCr5 steel is commonly used in industries such as automotive, mechanical engineering, and gear manufacturing. It is often chosen for applications like gear wheels, shafts, axles, and other components where a combination of strength, hardenability, and wear resistance is required.

16MnCr5 is a versatile steel that can be adapted to meet specific application requirements through heat treatment processes. Its well-balanced properties make it valuable for various applications in different industries, especially in situations where components need to withstand high stresses and wear.

20MnCr5 Steel

20MnCr5 (1.7147) 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.

The numerical composition “20MnCr5” indicates its alloying elements and approximate composition:

20 stands for the approximate carbon content (0.20%).

Mn represents manganese as a major alloying element.

Cr represents chromium as an alloying element.

5 signifies the approximate carbon content (0.5%) of chromium.

AISI 8620 Steel

AISI 8620, 20NiCrMo2, 1.6523) is a material suitable for cementation and nitration thanks to its low carbon content. 8620 steel is a ductile cementation steel where toughness is required in the core, hard and abrasion resistant on the surface and preferred in impact areas.

AISI 8620, 20NiCrMo2, 1.6523) is used in gear Wheel,pin, shaft,switch sleeve, Chain links and similar parts

18CrNiMo7-6 Steel

AISI 4820, 18CrNiMo7-6,1,6587 is a cementation steel alloyed with nickel, chromium and molybdenum. Surface hardness depth is much higher compared to 8620. Since 6587 steel, chromium and nickel alloy is much higher than 8620, its general mechanical properties are also better.

AISI 4820, 18CrNiMo7-6,1,6587 is used in Bushings wear pins, Bearings, Spr
