Process Practice to Prevent Edge Crack of 5 mm Hot Continuous-Rolled Strip Coil of S31803 Duplex Stainless Steel
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 add...

| Summary: | 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<sup>-6</sup>to 26 x 10<sup>-6</sup>increasing equiaxed zone ratio in cast slab, and-controlling slab heating temperature at 1 150 - 1 250℃. |
