304 stainless steel is a material widely used in various industrial fields, and the performance of its stamping parts is also of great concern. Regarding the yield point and hardness of 304 stainless steel stamping parts, the following is a detailed analysis.
1. Yield point
The yield point of 304 stainless steel, also known as yield strength, is a key indicator for measuring the plastic deformation of a material under the action of external force. For 304 stainless steel stamping parts, there is no fixed value for its yield point because it is affected by many factors, such as the composition of the material, processing technology, etc. However, in general, the yield strength of 304 stainless steel ranges from 200 to 550 MPa.
It is worth noting that since 304 stainless steel has no obvious yield strength, in some cases, people use conditional yield limit or yield strength to describe its performance. This refers to the stress value that produces 0.2% residual deformation when the material is subjected to external force. For 304 stainless steel, its conditional yield limit or yield strength is usually taken as 205 MPa.
2. Hardness
Hardness is an indicator of the material's ability to resist local deformation. For 304 stainless steel stamping parts, its hardness is also affected by many factors. In terms of hardness standards, the hardness of 304 stainless steel is usually expressed in HRB or HRC. Specifically, the HRB hardness range of 304 stainless steel is between 90100, while the HRC hardness range is between 2025.
In addition, the hardness of 304 stainless steel is also affected by its processing state and heat treatment process. For example, the hardness of 304 stainless steel after cold processing will increase, while the hardness of 304 stainless steel after heat treatment may decrease.
In summary, the yield point and hardness of 304 stainless steel stamping parts are important indicators of its performance. In practical applications, it is necessary to select appropriate materials and processing technology according to the specific use environment and requirements.
