ASME SA 515 Gr 60 vs SA 516 Gr 70

ASME SA 515 Gr 60 and SA 516 Gr 70 are carbon steel specifications for pressure vessel plates, but they differ in temperature service, grain structure, and toughness.

SA 515 Gr 60 is a carbon-silicon steel for intermediate and higher temperatures, while SA 516 Gr 70 is a carbon steel for moderate and lower temperatures with better impact properties. As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality ASME SA 516 GR 70 plates for pressure vessels, ensuring ASME compliance for global projects.

Overview of SA 515 Gr 60 and SA 516 Gr 70

SA 515 Gr 60 suits welded boilers and vessels in higher-temperature service, with coarser grain structure.

SA 516 Gr 70 is fine-grained and normalized for low-temperature toughness in pressure vessels.

The key distinction is service temperature: SA 515 for intermediate/high, SA 516 for moderate/low.

Gangsteel's ASME SA 516 GR 70 complements our range, including ASTM A 516 GR 70 for versatile needs.

The table below highlights key differences:

Chemical Composition Comparison

SA 515 Gr 60 has higher silicon for high-temperature strength, while SA 516 Gr 70 focuses on manganese for toughness.

Typical values (in weight %, maximum unless specified):

Gangsteel's ASME SA 516 GR 70 ensures precise control.

Mechanical Properties Comparison

SA 516 Gr 70 has higher yield strength for better performance under pressure.

Key values:

Gangsteel's plates, like ASTM A 516 GR 70, meet these specs.

Applications and Interchangeability

SA 515 Gr 60 is for high-temperature boilers and vessels.

SA 516 Gr 70 suits low-temperature pressure vessels and tanks.

They are not interchangeable due to temperature and toughness differences.

Gangsteel's offerings, including sa 283 grade c steel plate for lower-strength needs, complement SA 515 and SA 516.
