Carbon steel and austenitic stainless steel rolling clad plate manufacturing method therefor

A manufacturing method for a rolled clad plate of carbon steel and austenitic stainless-steel, characterized in that, it comprises the following steps:

• (1) preparing a blank material of a carbon steel layer and a blank material of a stainless-steel layer;
• (2) assembling the blank materials;
• (3) clad rolling;
• (4) cold rolling;
• (5) first annealing:
• wherein the plate is annealed at an annealing temperature of 1050-1150° C. and a holding time of greater than or equal to 30s;
• then cooled to room temperature, wherein in a cooling procedure, rapid cooling is performed in a temperature range of 900-500° C. with a cooling rate controlled to be 20-200° C./s;
• (6) second annealing:
• wherein the plate is heated at a heating rate greater than or equal to 5° C./s to a soaking temperature of 800-950° C., held for 10-100s, and then cooled at a rate of v1=3-20° C./s to a rapid cooling starting temperature T of ≥800-10xv1, and then cooled at a rate of 20-1000° C./s to 150-450° C.;
• and then subjected to an overaging treatment, wherein a overaging temperature is 150-450° C. and the overaging treatment time is 100-400s.
