Description
S7 is a general purpose air hardening tool steel having high impact and shock resistance. It has good resistance to softening at moderately high temperatures. This combination of properties makes it suitable for many hot-work and cold-work applications
Applications
Chisels, rivet sets, punches, driver bolts. Hot punching and shearing 
Physical properties (average values) at ambient temperature
Density [g/cm3]: 7.86
Coefficient of linear thermal expansion 10-6 oC-1
