Abstract

The invention relates to the field of metallic materials and discloses austenitic nonmagnetic steel. The austenitic nonmagnetic steel comprises the following components: 0-0.12 wt% of C, 6-9 wt% of Cr, 17.5-22.5 wt% of Mn, 0-1.0 wt% of Cu, 0.1-1 wt% of Si, 0-0.05 wt% of S, 0-0.7 wt% of Ni and the balance of Fe. The invention further discloses a balance block which is made of the austenitic nonmagnetic steel and used on a compressor, the compressor adopting the balance block, and application of the balance block in preparing the air condition compressor. The invention has the advantages that the prepared austenitic nonmagnetic steel is less susceptible to rustiness, small in magnetism, fast in demagnetization, high in toughness and applicable to producing the balance block used on the compressor, and has high application value.

Description

technical field [0001] The invention relates to the field of metal materials, especially stainless steel materials, in particular to an austenitic non-magnetic steel with relatively high manganese content. Background technique [0002] The compressor is the core component used in air conditioning devices such as air conditioners and refrigerators, and plays the role of compressing and driving refrigerant in the refrigeration circuit of air conditioners or refrigerators. In the compressor, the piston is usually used to compress and drive the refrigerant, that is, the reciprocating piston type. The piston reciprocates in the cylinder to change the working volume of the gas to achieve the purpose of compressing and driving the refrigerant. In addition, rotary compressors or screw compressors suitable for large refrigeration equipment use scrapers, also known as sliding vanes, to achieve compression. In a piston compressor, the movement of the driving piston requires the use of...
