Product Description:
ASTM A537 carbon steel plates are known for their superior tensile and yield strength compared to pressure vessel plates supplied under the ASTM A516 standard.
Our company can provide ASTM A537 Class 1 plates either from our existing stock or directly from the mill. We also offer a convenient in-house profiling service that allows for customized cutting to your desired size or shape.
Features:
ASTM A537 is a steel standard that specifies the chemical composition of the material along with its mechanical properties. The chemical composition of this grade of steel typically includes carbon, manganese, phosphorus, and sulfur. The aim is to maintain specific ranges of these elements to achieve the desired mechanical properties.
The mechanical properties of ASTM A537 are crucial in determining the suitability of the material for specific applications. The minimum yield strength for class 1 plates is 265 MPa (38,000 psi), but this increases for higher classes. This minimum yield strength denotes the amount of stress that the material can withstand before experiencing permanent deformation.
Another essential mechanical property is the tensile strength, which varies from 450 MPa (65,000 psi) to 620 MPa (90,000 psi) based on the class of the plate. Tensile strength is a measure of the maximum amount of stress that the material can withstand before breaking under tension.
Lastly, the minimum elongation tested in 200 mm is about 21%. This elongation value indicates the material's ability to deform plastically before fracturing. Therefore, this value is an indication of good ductility, a vital feature of materials that undergo plastic deformation under cyclic loading.
