i am looking for a graph of yield strength vs temp for 4130 steel, a bonus if the graph will shows various tempered 4130's too.
Yield strength is the amount of stress or force a material can withstand before it permanently deforms or breaks.
Yield strength is typically measured by subjecting a material to a controlled amount of stress and measuring the amount of deformation that occurs.
The yield strength of 4130 steel decreases as temperature increases. At room temperature, the yield strength for 4130 steel is around 63,000 psi, but at 500 degrees Fahrenheit, it decreases to around 50,000 psi.
As temperature increases, the atomic vibrations within the steel increase, causing the material to become more ductile and less able to resist deformation. This leads to a decrease in yield strength.
The decrease in yield strength at higher temperatures can affect the performance of 4130 steel in certain applications. It may not be suitable for use in high temperature environments where a high yield strength is required, but it is often used in lower temperature applications such as aircraft frames and automotive parts.
