Si Shengsheng stainless steel core and a fiber core code (natural or synthetic): FC, such as stainless steel wire rope FC. b natural fiber core: NF, such as NF stainless steel wire rope. c synthetic core: SF, SF such as stainless steel wire rope. d metal rope core: IWR (or IWRC), such as IWR stainless steel wire rope. e wire strand core: IWS, such as stainless steel wire rope IWS. Stainless steel wire rope damage grade stainless steel wire rope criteria Once operational it will inevitably produce damage until retirement, according to a stainless steel wire rope with different degree of damage can be grouped into four damage levels, different grades of stainless steel wire rope damage the security of both the difference . In order to make the majority of users have scientific criteria, reduce security risks, Shengyuan as we put together the following criteria damage grade stainless steel wire rope, for your reference. Grade Ⅰ injury: stainless steel wire rope original flaws or early expansion, basically does not affect the use of safety; stress-section loss rate <2.5%, the degree of harm - a slight degree. Ⅱ grade injury: stainless steel wire rope has produced "exhaustion injury" (bending fatigue), "contact injury" (extrusion plastic deformation, wear) and "erosion damage" (rust corrosion), etc., but it began to affect safety does not constitute a body damage; stress-section loss ratio ≥2.5% but <5% stainless steel wire rope ordering harmful levels - mild. Grade Ⅲ injury: stainless steel wire rope to further expand the existing injury aggravated stainless steel wire rope, and gradually form a destructive threat to the principal; stress-sectional loss ≥5% but <9.5%, the degree of harm to - moderate to severe. Super injury: stress-section loss ratio ≥9.5%, or more than the critical value of the industry to replace the rules of order; the degree of harm are - severe. These four damage grade in grade Ⅰ and Ⅱ injury damage the safety factor is still relatively high, but once you find the stainless steel wire rope used to reach grade Ⅲ injury or even super injury, to be replaced in order to guarantee the safe operation of stainless steel wire rope . Stainless steel wire rope production, Shengyuan stainless steel (certified), stainless steel wire rope provided by the Dongguan City Shengyuan Stainless.
