Multi-layer graphite with 316SS inserts
GRAPH-LOCK® 3128 HOCHDRUCK® is a multi-layer, high strength sheet material composed of .020” thick layers of high purity flexible graphite (carbon >99.85%) and .002” thick layers of 316 stainless steel foil insert. It provides high compressive strength, blow-out resistance, excellent handling properties, and improved tightness. Depending on the sheet thickness, several layers of graphite and stainless steel are bonded together in a proprietary process; no adhesive is used. Maximum ash content is 0.15%.
