Claims
- 1. A stainless clad steel sheet of about 0.5 to 0.8 mm thickness comprising a carbon steel sheet consisting of not more than 0.0045% of carbon, not more than 0.5% of manganese, not more than 0.080% of aluminum, not more than 0.02% of silicon contained as unavoidable impurity, not more than 0.0050% of nitrogen, and at least one of titanium and niobium under the following conditions:
- (Ti+Nb) . . . not more than 0.15% ##EQU4## with the balance being Fe, and an austenite stainless steel layer on at least one side of said carbon steel sheet.
- 2. The stainless clad steel sheet composite according to claim 1, wherein said stainless steel layer on one side of said carbon steel sheet has a thickness amounting to from 2.5 to 30% of the total thickness of the clad steel sheet.
- 3. The stainless clad steel sheet composite to claim 1, wherein said stainless steel layer contains not more than 0.05% of carbon.
- 4. The stainless clad steel sheet composite according to claim 1, which is obtained by hot rolling a stainless clad steel slab prepared by a continuous casting method.
- 5. The stainless clad steel sheet composite according to claim 1, which is obtained by hot rolling and cold rolling a stainless clad steel slab prepared by a continuous casting method.
- 6. The stainless clad steel sheet composite according to claim 1, which is obtained by hot rolling a stainless clad steel slab, and annealing at a temperature not lower than 900.degree. C.
- 7. The stainless clad steel sheet composite according to claim 1, which is obtained by hot rolling a stainless clad steel slab with a finishing temperature not lower than 900.degree. C. and hot coiling at a temperature not higher than 600.degree. C.
- 8. The stainless clad steel sheet composite according to claim 1, which is obtained by hot rolling a stainless clad steel slab, annealing at a temperature not lower than 900.degree. C., cold rolling with at least 10% reduction, and annealing at a temperature in a temperature range of from a recrystallization temperature of said stainless steel layer to 1100.degree. C.
- 9. The stainless clad steel sheet composite according to claim 1, which is obtained by hot rolling a stainless clad steel slab, hot coiling at a temperature not higher than 600.degree. C., cold rolling with at least 10% reduction, and annealing at a temperature in a temperature range of from a crystallization temperature of the stainless steel layer to 1100.degree. C.
