Yield Strength of Grade E Steel and Comparison with Other Grades

TAGS: steel | grade | strength |

Yield strength is an important factor to consider when selecting a steel grade for a particular application. It represents the maximum stress that a material can withstand before it begins to deform permanently. In the steel industry, yield strength is typically measured in pounds per square inch (psi) or megapascals (MPa). In this article, we will discuss the yield strength of grade E steel and how it compares to other grades.

Grade E steel is a low carbon, pressure vessel quality steel that is commonly used in the construction of tanks, boilers, and other similar applications. According to the American Society of Mechanical Engineers (ASME) code, the minimum yield strength of grade E steel is 34,000 psi (234 MPa). This means that the material can withstand a maximum stress of 34,000 psi before it begins to deform permanently.

Compared to other grades, the yield strength of grade E steel is relatively low. For example, grade A514 steel, which is commonly used in structural applications such as bridges and buildings, has a minimum yield strength of 100,000 psi (690 MPa). Grade 70, another commonly used pressure vessel quality steel, has a minimum yield strength of 38,000 psi (260 MPa).

However, it is important to note that yield strength is not the only factor to consider when selecting a steel grade. Other factors such as tensile strength, ductility, and weldability should also be taken into account. In addition, the specific application will also play a role in determining the appropriate grade of steel to use.

the yield strength of grade E steel is 34,000 psi according to ASME code, which is relatively low compared to other grades such as grade A514 and grade 70. However, yield strength is just one factor to consider when selecting a steel grade for a particular application. Other factors such as tensile strength, ductility, and weldability must also be taken into account.
