DIN 1652-3 Grade 20CrS4 treated to ferritic-pearlite structure and cold-drawn
DIN 1652-3 Grade 20CrS4 treated to ferritic-pearlite structure and cold-drawn introduction
The steel 20 CrS 4 is used for high wear loaded and better machinable parts in the vehicle and mechanical engineering (e.g. camshafts, piston pins, gears).
The lowest application amounts to -25 °C, the best application from 5 to 10 mm nominal size.
Equivalent material: ISO 20CrS4, DIN 1.7028, JIS SCr22H, JIS SCr420H, JIS SCr420, EN 20CrS4, EN 1.7028
