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.

Those are just some of the benefits that our cold rolled, high strength low alloy GS (Greer Steel) formable steels have to offer. Perfect for applications such as bumpers, fasteners, springs, brackets, supports and other formed parts where higher strength is required and greater yields are desired.
Sep 12, 2016· This action results in better shape, but it also increases the strength and lowers the elongation. If you are buying a coil based only on chemistry, the mill can supply you with either coil to satisfy your order. On parts that have potential forming concerns, it is advisable to get a tensile .
Pearlitic Nodular Cast Iron Rolls. Pearlitic and Pearlitic / Sorbitic Nodular Iron are nodular grades alloyed with Cr, Ni, and Mo with Ni ranging between 1.50 % in the softer grades and 4 % in the harder grades.

Aluminum 2024-T3/T4/351/851 Product Guide Applications | Aluminum 2024 Specifications | Related videos | Mechanical and Chemical Data Overview. Copper is the main alloying ingredient in 2024 aluminum. It is very strong compared to most aluminum alloys, and has average machinability, but the copper component of this alloy makes it susceptible to corrosion.
"High Performance Steel" is the designation given to the steel that offers higher performances in tensile strength, toughness, weldability and cold formability and corrosion resistance than those generally used in bridge construc-tion. Some of these high performance steels have already been specified in the Specifications for Highway Bridg-
A type of cold-rolling mill, the tandem mill imparts greater strength, a uniform and smoother surface, and reduced thickness to the steel sheet. Unlike the original single-stand mills, a tandem mill rolls steel through a series of rolls (generally three to five in a row) to achieve a desired thickness and surface quality. Tantalum 5

Nov 19, 2014· Tensile strength of paper is expressed in N/m (Force per unit length) everywhere. I am looking for a way to convert the tensile strength of paper to N/m^2 (Force per unit area). I assume this is because the paper strength might not be proportional to its cross sectional area. It should calculated separately for each paper weight
