9SMN PB36K/28K-12L14 LEADED FREECUTTING STEEL
FOREIGN RELATED SPECIFICATIONS
STANDARD
GERMAN MAT. NO		 DIN SAE AISI JIS
- 500492.2 - - -
TYPICAL USES - High speed production of repetition work (e.g. manufacture of bushes, pins, bolts, nuts, studs and couplings) where the major requirements are rapid machining and maximum tool life. Cutting speeds on bright drawn freecutting steel bar are considerably above those of ordinary freecutting quality steel with a far superior surface finish.

070M55 BLACK “55”
CARBON STEEL (EN9)
FOREIGN RELATED SPECIFICATIONS
STANDARD
GERMAN MAT. NO		 DIN SAE AISI JIS
1,1209 CM55 1055 1055 -
TYPICAL USES - Similar in all applicants to 080m40 (EN8), but by virtue of the higher carbon content has the extra strength which is sometimes required. Exhibits good wear-resistance. This material can be successfully flame hardened. (gear and sprocket teeth are often surface hardened in this manner).
