Ultra-high strength stainless steel grades
We offer stainless steel grades ranging from strength class 8.8 to 15.9 for applications where downsizing, clamping force and strength are critical. Our grades offer a unique combination of strength and good ductility.
Benefits of high-strength fastener grades:
Higher resistance against relaxation.
Opportunities to downsize, decrease weight or reduce the number of fasteners while maintaining clamping load.
Ability to optimise overall assembly or product design.
Ability to withstand higher static or dynamic stresses.
Greater safety.
