Abstract

The invention discloses an austenitic acid-resistant stainless steel pipe. The austenitic acid-resistant stainless steel pipe comprises a steel pipe body. A plurality of antiskid stripes are arranged on the outer surface layer of the steel pipe body. A plurality of inner clamping grooves are formed in the inner surfaces of the two ends of the steel pipe body. The end surfaces of the two ends of the steel pipe body are an outer inclined surface and an inner inclined surface correspondingly. The steel pipe body comprises, by weight, 0.45% of C, 0.7% of Si, 1.8% of Mn, 23% of Cr, 13% of Ni, 1.1% of Nb, 0.01% of S, 0.01% of P, 6% of Ta, 0.3% of Zr and 0.2% of Nb. The austenitic acid-resistant stainless steel pipe is simple in structure, reasonable in design and simple in processing step and has the acid resistance, installation and antiskid operation are convenient, and meanwhile, the hardness is high.

Description

technical field [0001] The invention relates to an austenitic acid-resistant stainless steel pipe and its manufacture.
