Does anyone happen to know of a good reference for ASTM A572 (any grade) that lists temperature effects on yield? The standard only lists room temperature specs.
Thanks
Thanks
Hey Q. Good to see you.Q_Goest said:Hi Fred,

ASTM A572 is a standard specification for high-strength low-alloy (HSLA) structural steel. It outlines the chemical composition and mechanical properties of various grades of steel, including A572 Grade 50, which is commonly used in construction and other applications.
The yield strength of ASTM A572 steel decreases as temperature increases. This is due to the fact that at higher temperatures, the steel undergoes a reduction in its internal strength due to changes in the microstructure. As a result, the steel becomes more ductile and less able to resist deformation, resulting in a lower yield strength.
The maximum service temperature for ASTM A572 steel is 450°F (232°C), according to the standard specification. However, the actual temperature limit for a specific grade of A572 steel may vary depending on its chemical composition and other factors.
Using ASTM A572 at high temperatures can result in reduced strength and stiffness, which can lead to structural instability and failure. It can also cause changes in the microstructure of the steel, such as softening, which can affect its mechanical properties and performance.
The effects of temperature on ASTM A572 can be mitigated by using other materials or grades of steel that are specifically designed for high-temperature applications. Additionally, proper design and fabrication techniques can also help minimize the impact of temperature on the performance of ASTM A572 steel.
