Problems solved by technology

The invention has good heat resistance, but the alloy contains more expensive Ni elements, and the production cost is higher
[0005]Application No. 200910227928.2 Chinese invention patent discloses a continuous casting method for austenitic heat-resistant stainless steel, through ladle casting and tundish casting , billet drawing and billet cutting steps to obtain an austenitic heat-resistant stainless steel. The upper and lower surfaces of the slab produced by the invention are smooth and smooth without longitudinal cracking, but the annealing process is not used, and the heat-resistant effect is not good
[0006] Through the comparison and analysis of the above patents, it can be seen that the stainless steel in the prior art cannot fully meet the current use and manufacturing requirements, and has disadvantages such as poor heat resistance and high cost, so it is necessary to Development of a stainless steel material with high heat resistance and low cost
