Spectrographic Analysis Micrographic Analysis Magnaflux Crack Detection Fatigue Cycle Test Dimension Examination Tensile Test, Capacity 200 tons ■ ■ Magnaflux Crack Detection: All forged components, each individually magnaflux detected after heat treatment. ■ ■ Proof Load Testing: Chain and components are proof load tested at 2.5 times the Working Load Limits with resultant permanent deformation within 1%. ■ ■ Dynamic Fatigue Testing: Batch samples of chain and components are Dynamic Fatigue Tested at 1.5 times Working Load Limit for 20,000 cycles. ■ ■ Ultimate Breaking Load Testing: Batch samples are Break Load Tested in a static tensile testing machine to ultimate failure. The minimum ultimate force is equal to the Working Load Limit times the safety factor. ■ ■ Spectrographic Analysis: To assure of the proper metallurgy content of all raw materials. ■ ■ Eddy Current Detection: All load pins are 100% individually inspected after heat treatment.
