Abstract

The invention discloses 06Cr18Ni11Ti austenitic stainless steel and a preparation method thereof. The alpha-phase area content of the 06Cr18Ni11Ti austenitic stainless steel is 2%-8%, and the effects that welding performance is facilitated, and the use performance of materials is not influenced are achieved.

Description

technical field [0001] The invention relates to the field of preparation of 06Cr18Ni11Ti austenitic stainless steel, in particular to a 06Cr18Ni11Ti austenitic stainless steel and a preparation method thereof. Background technique [0002] 06Cr18Ni11Ti austenitic stainless steel not only has all the characteristics of other austenitic stainless steels, but also has the characteristics of high high temperature yield strength, strong resistance to intergranular corrosion, strong high temperature fatigue resistance, and can work in harsher environments for a long time. The first choice for forgings of internals of sea-mounted nuclear reactors. [0003] In austenitic stainless steel, the ferrite content is usually determined by the chemical composition. In actual equipment manufacturing, according to the performance and environmental characteristics of the material, it is determined which chemical composition of austenitic stainless steel to choose. But no matter what kind of ...
