摘要

Given the significant impact of temperature on the forming and service performance of austenitic stainless steel components during manufacturing and operation, this study focuses on 304 stainless steel. The effects of temperature environments, such as forming, welding, and service, on the parts were simulated by hot tensile tests and room temperature tensile tests after temperature treatment, and the influence of different temperature environments on the mechanical properties of 304 stainless steel was revealed. The hot tensile test results indicate that the tensile properties of the specimens are negatively correlated with temperature. The maximum reductions in ultimate tensile strength and yield strength are 95.64% and 91.552%, respectively. The decline trends follow an ExpLinear function relationship below 400°C and a linear function relationship above 400°C. After temperature treatment, the room-temperature tensile test results show that the overall tensile properties are less affected by the treatment temperature, with variations in ultimate tensile strength, elastic modulus, and elongation all within 10%. The yield strength decreases continuously when the temperature exceeds 500°C, with a maximum reduction of 18.332%, following a trend that fits a Gaussian function relationship.
