thread rolling bs 970

BS EN 18 steel equivalent ? Material engineering general

Mar 11, 2006· Thread rolling produces a higher quality thread for the following reasons1. Improved surface quality (lower surface roughness) 2. Improved strength and hardness due to strain hardening (cold working) 3. Improved fatigue life due to residual compressive stresses when Copper Bonded Grounding Rod, Grounding Rods, Earthing "HEX" copper bonded earth rod are made from low carbon steel of grade BS 970 or AIS11018 with a high tensile strength of atleast 600 N/mm2 . Low carbon steel core are molecularly tended with 99.9% pure electrolytic copper. Salient Features. Perfectly bonded rod will lost longer, drive easier and will not crack.Stainless Steel Bolts & Nuts 304, 316 Manufacturers bs 970 X 5 CrNiMo 17 12 2 Over the past few years we have manufactured many different kind of stainless steel grades of bolts and nuts, however the the above grades mentioned in the table are the main grades which we are manufacturing consistantly.
