摘要： A spiral wound gasket (20) is disposed between joint members (22, 24) of a hot fluid joint to seal a gap (48) therebetween. The spiral wound gasket (20) includes a first high temperature performance metallic strip (28) formed of a thermally conductive alloy, including, Ni Cr, and Fe, spirally wound around a central axis (A) to present a first high temperature performance metallic winding (30) exposed to hot fluids. A first non-metallic filler strip (32) formed of a mica material is spirally wound outwardly of the first high temperature performance metallic winding (30) to form a first non-metallic filler winding (34). A second high temperature performance metallic strip (36) formed of a stainless steel material is spirally wound outwardly of the first non-metallic filler winding (34). A second non-metallic filler strip (40) formed of a graphite material is spirally wound outwardly of the second high temperature performance metallic winding (38).

摘要： A metal gasket includes embossments that exhibit essentially full functional recovery and full retained internal stress at temperatures up to about 1000° F. which is made from sheet material that is cold rolled and whose embossments are work hardened without any post embossment heat treating that would act to harden the material. This material may also receive a precipitation hardening heat treatment prior to being embossed. The gasket materials include alloys having greater than about 18% Ni, greater than about 14% Cr, from about 0.1 to 10% of at least one of Mo, Ti, V, Al, Co, Nb, Ta or Cu and the balance Fe with incidental impurities, which are cold rolled without any post embossment heat treating that would act to harden the material.

摘要： The invention provides a sheet metal joint and a method for forming a sheet metal joint. The sheet metal joint includes first and second metal sheets disposed in a parallel relation to one another. Each of the first and second metal sheets has a plurality of perforations with a tang extending from each perforation. The tangs of the second sheet and the tangs of the second metal sheet are curled together in opposite rotational directions. The tangs of the first metal sheet space the first and second metal sheets from one another and the tangs of the second metal sheet substantially fixedly engage the first and second metal sheets with respect to one another.

摘要： A metal gasket for use in sealing between a cylinder head and a block of an engine includes at least one layer formed with at least one opening therethrough and a deformation feature in the form of a sealing bead, stopper, or both surrounding the opening. The gasket layer is fabricated of austemper-hardenable steel formed when in an annealed state and thereafter austempered to harden the layer and relieve residual forming stresses. During austempering, the layer is supported in a porous fixture that retains the layer against movement out of its plane while permitting it to move within its plane. The fixture has coarse expanded metal exoskeleton liner with wire mesh panels. The mesh liners maintain molten salt against the layers which acts as a thermal cushion to discourage warpage.

摘要： A heat treat fixture is provided for supporting thin sheet-like work pieces, such as metal gasket layers, during heat treatment to achieve uniform hardness and properties of the work piece while preventing warpage. The fixture has porous, planar support walls that engage the opposite sides of the work piece. The walls include a coarse porous exoskeleton of expanded metal and an inner liner of wire mesh panels that are considerably finer than the coarse exoskeleton. The porous walls permit liquid heating and cooling media during heat treatment to flow freely through the walls for intimate contact with the work piece to achieve rapid uniform heating and cooling. The work piece is supported by the porous walls against movement out of its plane while being permitted to expand and contract within its plane to minimize warpage.
