Crack detection on sheared-edge of ultra-high strength steel sheet by using acid immersion
t. In trimming of ultra-high strength steel (UHSS) sheet, the high strength of the sheet usually results in large fracture and low burnish surfaces on the sheared-edge.

description |
t. In trimming of ultra-high strength steel (UHSS) sheet, the high strength of the sheet
usually results in large fracture and low burnish surfaces on the sheared-edge. For metal
stamping industries, large fracture surfaces are unwanted, as it not only deteriorates shearededge quality but also leads to delayed-crack. In this study, crack detection by using acid
immersion on the sheared-edge of ultra-high strength steel sheet caused by the trimming process
was investigated. The ultra-high strength steel sheet of JSC780YN, JSC980YN, and
JSC1180YN having different strengths were trimmed and immersed in 35% hydrochloric acid
under a controlled time interval. The steel sheet with higher strength was found to produce larger
fracture surface after trimming, i.e. more than 50% of the entire sheared-edge is fracture surface.
Besides, the larger fracture surface of the steel sheet results in higher crack exposure and higher
crack propagation, which in the long run, it can cause failure to the part manufactured using
UHSS. |
