Tensile Strength The tensile force required to produce a rupture in a strip of paper or paperboard, measured in MD CD, expressed in kN/m. Tensile strength is indicative of fiber strength, fiber bonding and fiber length. Tensile strength can be used as a potential indicator of resistance to web breaking during or converting.
Bolts are manufactured by forging from round bar sections, usually with a hexagon shaped head. The steel material for bolts has a higher strength than ordinary structural steel, usually with an ultimate tensile strength of 800 or 1000 N/mm² and the material for nuts has a similar or higher strength.
