Abstract: A supermartensitic stainless steel having high mechanical strength and corrosion resistance showing the following percentage composition C.ltoreq.0.05; Cr 12-15; Ni 4-7; Mo 1.5-2; N 0.06-0.12; Mn 0.5-1; Cu<0.3; P<0.02; S.ltoreq.0.005; Al<0.02; Si.ltoreq.1; the rest being iron and minor impurities, with the further requirement that the percentages of Cr, Mo and N satisfy the following formula: (Cr+3.3 Mo+16 N).gtoreq.19. Said steel allows to obtain manufactured articles having excellent mechanical strength and corrosion resistance characteristics.

Abstract: This invention is directed to means (40) for severing multiple, electrical connector housings (10) into single units. The apparatus hereof features a cutting or web severing station (40) comprising one or more horizontally reciprocating cutting bars (30), each said bar (30) at one end thereof having means (32) for mounting same on a pivoting lever arm (46, 52), and at the opposite end (34) a 1) hold-down flange (36) which acts to restrain any vertical movement of said webs, and 2) recessed web severance portion (38). Cooperating with said bar(s) is an essentially "L" shaped lever arm (46) mounted for pivotal action at the junction of the arms thereof, where one arm (48) is mounted for vertical movement by means of a hydraulic piston (50). By virtue of said vertical movement, the remaining lever arm (52), to which such cutting bar (30) is mounted, is caused to reciprocate within a given plane between a web severance position "B" and a remote position "A.
