Abstract

The invention discloses a stainless material. The stainless material comprises following chemical compositions in terms of weight percentage: no more than 0.08 percent of C, no more than 1.00 percent of Si, no more than 2.0 percent of Mn, no more than 0.035 percent of P, no more than 0.03 percent of S, 24 percent to 26 percent of Cr, 18 percent to 20 percent of Ni, 1.5 percent to 2.5 percent of Cu and the balance of Fe. The invention has the following advantages: firstly, the casting technique property of the material is good, no great number of casting defects exist and the technique yield is high; and secondly, the alkali-resistant and acid-resistant properties of the material are good, being equal to the 310S of national grade.

Description

technical field [0001] The invention relates to the field of materials, more specifically, it relates to a stainless steel material. Background technique [0002] Although the national grade 310S stainless steel material has excellent performance in acidic and alkaline environments, its cost is high, its process performance is poor, and its performance in casting fluidity, casting process yield and processing technology is not good. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a stainless steel material with excellent corrosion resistance and superior artistic performance in acid-base environment. [0004] The purpose of the present invention is achieved through the following technical solutions. For this stainless steel material, the chemical composition weight percentage of the stainless steel is: C is ≤0.08%, Si is ≤1.00%, Mn is ≤2.0%, P is ≤0.035%, S is ≤0.03%, and Cr is 24-26%. ...
