astm a537 class 1 chemical composition, mechanical properties

ASTM A537 Class 1 is a normalized, heat-treated carbon manganese-silicon steel plate intended for pressure vessel applications. Here are the typical chemical composition and mechanical properties of ASTM A537 Class 1 steel:

Chemical Composition (Percentage by weight):

Carbon (C): 0.24% max

Manganese (Mn): 0.70-1.35%

Phosphorus (P): 0.035% max

Sulfur (S): 0.035% max

Silicon (Si): 0.15-0.50%

Mechanical Properties:

Tensile Strength: 485-620 MPa (70,300-89,900 psi)

Yield Strength: 345 MPa (50,000 psi) min

Elongation in 2 inches (50mm): 22%

Additional Information:

Thickness: The material is typically available in thicknesses ranging from 6mm to 150mm.

Heat Treatment: ASTM A537 Class 1 material is usually supplied in the normalized condition.

Impact Test Requirement: The material typically requires Charpy V-notch impact testing at specified temperatures.

Please note that these values are typical and may vary slightly based on the specific manufacturer, heat treatment, or exact product form. Always refer to the latest ASTM A537 standard specifications for precise and up-to-date information before using this material in any application.
