ASME SA 515 Gr 60 vs SA 515 Gr 70

ASME SA 515 Gr 60 and Gr 70 are carbon steel plate specifications under ASME SA 515/SA 515M, designed for intermediate and higher temperature pressure vessels. Both grades are killed or normalized for improved toughness, but Gr 70 provides higher tensile strength for more demanding service conditions. As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality pressure vessel steels, including equivalents to SA 515, ensuring ASME compliance for global projects.

Overview of SA 515 Gr 60 and Gr 70

SA 515 Gr 60 offers a tensile strength range of 60-80 ksi (415-550 MPa), suitable for moderate-pressure vessels.

SA 515 Gr 70, with 70-90 ksi (485-620 MPa), is preferred for higher loads and temperatures.

Both are low-carbon steels, but Gr 70's enhanced properties make it ideal for critical applications.

Gangsteel's plates, similar to our ASME SA 516 GR 70, support these specs with rigorous testing.

The table below highlights key differences:

Chemical Composition Comparison

Both grades have similar compositions, with Gr 70 allowing slightly higher carbon for strength.

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

Gangsteel's production, akin to ASTM A 516 GR 70, ensures precise control.

Mechanical Properties Comparison

Gr 70's higher tensile strength enhances load capacity.

Key values:

These properties make Gr 70 more robust for elevated temperatures.

Gangsteel's plates match these, similar to asme sa 36 steel plate for structural ties.

Applications and Interchangeability

SA 515 Gr 60 suits moderate-pressure boilers and tanks.

Gr 70 is for higher-temperature vessels and critical service.

They are not fully interchangeable; Gr 70 requires for demanding conditions.

Gangsteel's offerings, including sa 283 grade c steel plate, complement SA 515 for varied needs.

FAQ
