SA 283 gr c vs sa 285 gr c

SA 283 Gr C vs SA 285 Gr C

ASME SA 283 Gr C and SA 285 Gr C are both low-carbon steel plate specifications with similar mechanical properties, but they differ in intended applications and some chemical limits. SA 283 Gr C is for general structural use, while SA 285 Gr C is specifically for pressure vessels with stricter requirements for boilers and tanks.

As a leading Chinese manufacturer and exporter, Gangsteel offers high-quality sa 283 grade c steel plate under asme sa 283/sa 283m, providing cost-effective options for structural projects where pressure vessel specs are not required.

What is ASME SA 283 Gr C and SA 285 Gr C

SA 283 Gr C is a low to intermediate tensile strength carbon steel under ASME SA 283 for general structural applications, not permitted for pressure-retaining use due to less stringent controls. SA 285 Gr C is a pressure vessel steel under ASME SA 285, designed for fusion-welded boilers and vessels with similar strength but better suitability for high-pressure environments. Gangsteel's sa 283 grade c steel plate is ideal for non-pressure structural needs, complementing our range including sa 283 grade a steel plate, sa 283 grade b steel plate, and sa 283 grade d steel plate.

The table below summarizes key differences:

Chemical Composition Comparison

SA 283 Gr C and SA 285 Gr C have similar compositions, but SA 285 has slightly higher carbon allowance for pressure vessel suitability. Below is a table of typical compositions (in weight %, maximum unless specified):

Gangsteel's sa 283 grade c steel plate adheres to these for optimal performance.

Mechanical Properties Comparison

Both grades have identical mechanical requirements, with no impact testing mandated. The table below details typical values:

Gangsteel's asme sa 283/sa 283m plates provide these properties for structural reliability.

Applications and Interchangeability

SA 283 Gr C is for general structures and low-pressure tanks, while SA 285 Gr C is for pressure vessels and boilers with stricter chemical controls. They are not always interchangeable due to application restrictions. Gangsteel's plates support both with certifications.
