ASME SA 516 Gr 60 vs 70

ASME SA 516 Gr 60 vs 70

ASME SA 516 Gr 60 and Gr 70 are carbon steel plate specifications under ASME SA 516/SA 516M, designed for pressure vessels operating at moderate and lower temperatures. Both grades are normalized for enhanced toughness, but Gr 70 offers higher tensile strength and yield strength, making it suitable for more demanding applications.

As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality ASME SA 516 GR 60 and ASME SA 516 GR 70 plates, ensuring compliance with ASME standards for global projects in boilers and pressure vessels. Our offerings also include related grades like ASME SA 516 GR 55 and ASME SA 516 GR 65 for versatile applications.

Overview of ASME SA 516 Gr 60 and Gr 70

ASME SA 516 Gr 60 and Gr 70 are carbon-manganese steels used for pressure vessel fabrication, normalized to improve notch toughness and suitable for welded applications. Gr 60 has a minimum tensile strength of 60-80 ksi (415-550 MPa), while Gr 70 provides 70-90 ksi (485-620 MPa), making it stronger for higher-pressure environments. Gangsteel's ASME SA 516 GR 60 and ASME SA 516 GR 70 plates are engineered for reliability, complementing other structural grades like asme sa 283/sa 283m and asme sa 36 steel plate for diverse project needs.

The table below compares key specifications:

Chemical Composition Comparison

Both grades have similar compositions, with Gr 70 allowing slightly higher carbon for increased strength. Below is a table of typical compositions (in weight %, maximum unless specified):

Gangsteel's ASME SA 516 GR 60 and ASME SA 516 GR 70 plates adhere to these limits, ensuring performance for pressure vessel applications.

Mechanical Properties Comparison

Gr 70's higher strength makes it suitable for more demanding conditions than Gr 60. The table below details mechanical properties:

Gangsteel's plates, including ASTM A 516 GR 60 and ASTM A 516 GR 70, meet these requirements through rigorous testing.

Applications and Interchangeability

SA 516 Gr 60 is used for moderate-pressure vessels and boilers, while Gr 70 is preferred for higher-pressure applications due to its superior strength. They are not interchangeable where higher strength is critical. Gangsteel's plates, including sa 283 grade c steel plate for less demanding uses, complement SA 516 for varied project needs.
