Products Description
Standard regulations
According to the ASTM A387/A387M standard, the upper limit of the service temperature of A387 Gr.11 steel plates varies under different service environments and design conditions.
Generally speaking, under the condition of reasonable design and meeting the corresponding manufacturing specifications, the upper limit of the long - term service temperature of A387 Gr.11 steel plates is approximately 550 - 593 °C (1022 - 1100 °F).
Influencing factors
Chemical composition stability: Elements such as chromium and molybdenum in the chemical composition of A387 Gr.11 steel plates improve the oxidation resistance. However, if it is used in a high - temperature environment for a long time, the chemical composition may undergo microscopic changes, affecting its performance. For example, an excessively high temperature may lead to the aggregation and growth of carbides, thereby reducing the strength and toughness of the material.
Change in mechanical properties: As the temperature rises, the mechanical properties such as yield strength and tensile strength of the steel plate will gradually decrease. When approaching or exceeding the upper limit of the service temperature, the material may not be able to bear the designed load, resulting in structural failure.
Limit of oxidation resistance performance: Under a high - temperature environment, an oxidation reaction will occur on the surface of the steel plate. Although the A387 Gr.11 steel plate has good oxidation resistance, after exceeding a certain temperature, the oxidation rate will accelerate and the thickness of the oxide layer will increase, which may cause the oxide scale to peel off and affect the service life of the material.

Creep phenomenon: Under high temperature and continuous stress, A387 Gr.11 steel plates will undergo creep. Creep refers to the phenomenon that the material undergoes slow plastic deformation over time under a constant stress. When the temperature approaches or exceeds the upper limit of the service temperature, the creep speed will accelerate, which may cause the deformation of the material to exceed the allowable range of the design and affect the normal operation of the equipment.
