Grade U.S. [SI]
60 [415]	60–80 [415–550]
65 [450]	65–85 [450–585]
70 [485]	70–90 [485–620]

Chemical Composition: ASTM A515 plates typically consist of carbon, manganese, phosphorus, sulfur, and silicon, with specific limits on these elements to achieve desired mechanical properties.

Grade 60: Yield Strength: Minimum 207 MPa (30,000 psi); Tensile Strength: 415 - 550 MPa (60,000 - 80,000 psi); Elongation: Minimum 21% in 200 mm.

Grade 65: Yield Strength: Minimum 241 MPa (35,000 psi); Tensile Strength: 450 - 590 MPa (65,000 - 85,000 psi); Elongation: Minimum 20% in 200 mm.

Grade 70: Yield Strength: Minimum 276 MPa (40,000 psi); Tensile Strength: 485 - 620 MPa (70,000 - 90,000 psi); Elongation: Minimum 19% in 200 mm.

ASTM A515 steel plates are commonly used in:

Manufacturing of pressure vessels for the oil and gas industry.

Construction of boilers and heat exchangers.

Fabrication of industrial storage tanks and other pressure-sensitive equipment.

Applications where high strength and durability are required, especially in high-temperature environments.

In summary, ASTM A515 steel plates provide a robust and reliable solution for various applications in the pressure vessel and boiler manufacturing sectors, ensuring safety and performance in demanding conditions.
