Abstract

The invention discloses austenitic stainless steel and a preparing method thereof and particularly relates to the technical field of austenitic stainless steel preparation. Raw materials include, by weight, 18-20 parts of chromium, 8-10 parts of nickel, 0.1-0.3 part of carbon, 1-3 parts of molybdenum, 0.1-0.4 part of copper, 0.02-0.06 part of silicon, 0.02-0.05 part of niobium, 0.4-0.8 part of titanium, 2-4 parts of iron, 8-16 parts of glass fibers, 10-14 parts of carbon fibers, 4-10 parts of aluminum oxide and 8-12 pats of copper oxide, and auxiliary materials include, by weight, 2-8 parts ofepoxy resin and 2-8 parts of colloidal graphite powder. The prepared austenitic stainless steel is good in insulation, high in heat resistance, good in corrosion resistance and high in mechanical strength; besides, spraying liquid prepared by mixing and stirring powder formed by grinding iron, carbon fibers, aluminum oxide and copper oxide, epoxy resin and the colloidal graphite powder is evenlysprayed to castings, the abrasion resistance and the hardness of the austenitic stainless steel are effectively improved, and the service life of the austenitic stainless steel is effectively prolonged.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of austenitic stainless steel preparation, and in particular to an austenitic stainless steel and a preparation method thereof. Background technique [0002] In layman's terms, stainless steel is steel that is not easy to rust. In fact, some stainless steel has both stainless and acid resistance (corrosion resistance). The stainless steel and corrosion resistance of stainless steel are due to the chromium-rich oxidation on its surface. The formation of a film (passive film), this rust and corrosion resistance are relative. There are many classification methods for stainless steel. According to the structure at room temperature, there are martensitic, austenitic, ferritic and duplex stainless steels. According to the main chemical composition, they can be basically divided into two types: chromium stainless steel and chromium-nickel stainless steel. For large systems, there are nitr...
