Abstract
This paper focuses on the influencing factors of stainless steel tensile strength and its improvement measures. First, the basic knowledge of stainless steel, the mechanical properties research, and the basic theory of the tensile properties of the material are summarized. Subsequently, the four major factors affecting the tensile strength of stainless steel: tissue factor, composition factor, heat treatment process parameters and surface modification factor are explored in detail, and the specific influence of these factors on the tensile strength of stainless steel is verified through experiments. Based on this, this paper proposes targeted improvement measures, including optimizing the stainless steel tissue structure, adjusting the optimal allocation ratio of element composition, improving the quality and stability of the heat treatment process, and improving the surface treatment process, to improve the tensile strength of stainless steel. These measures can not only help to have a deep understanding of the performance characteristics of stainless steel materials, but also provide an important theoretical basis and practical guidance for the research and development, production and application of stainless steel materials. The research results of this paper are of great significance for promoting the development and application of stainless steel materials.
