Case hardening · EN 10084
Carburising steel — hard, wear-resistant skin over a tough core.
1.713116MC5Ø 4 – 19 mm
Why this grade
Low carbon keeps the core tough; manganese and chromium give the carburised case deep, even hardness. It is a standard choice for transmission parts that see both impact and wear.

How we anneal it
Spheroidise / soft anneal
Softens the chromium steel enough for cold forging of pins and gear blanks.
