Edge crack of 5 mm strip coil of S31803 duplex stainless steel ( % :0. 019C
22. 50Cr
5. 40Ni
3. 15Mo
0. 18N) rolled from 200 mm slab is often occurred. It is available to prevent the formation of edge crack of 5 mm hot continuous-rolled strip coil by controlling S content in steel ≤0. 005% and adding RE-Si-Fe alloy to modify sulfide
decreasing oxygen content in steel from 53 x 10
-6
to 26 x 10
-6
increasing equiaxed zone ratio in cast slab
and-controlling slab heating temperature at 1 150 - 1 250℃.
