SA 283 gr c vs sa 516 gr 70

What is SA 283 Gr C vs SA 516 Gr 70?

ASME SA 283 Gr C and SA 516 Gr 70 are both carbon steel plate specifications, but they differ in strength, heat treatment, and applications. SA 283 Gr C is a low-carbon steel for moderate-strength structures, while SA 516 Gr 70 is a normalized steel for higher-pressure vessels with superior toughness. 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 projects requiring moderate performance compared to SA 516 Gr 70.

Overview of SA 283 Gr C and SA 516 Gr 70

SA 283 Gr C is a low-carbon steel under ASME SA 283 for general structural and low-pressure vessel use, offering good weldability without heat treatment. SA 516 Gr 70 is a carbon-manganese steel under ASME SA 516, normalized for improved toughness in moderate and lower temperature pressure vessels. Gangsteel's sa 283 grade c steel plate is ideal for less demanding applications, 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 has lower carbon for better weldability, while SA 516 Gr 70 includes more manganese for toughness. 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

SA 283 Gr C has lower strength than SA 516 Gr 70, making SA 516 suitable for higher pressures. The table below details typical values:

Gangsteel's asme sa 283/sa 283m plates provide moderate strength close to SA 516 for cost-effective use.

Applications and Interchangeability

SA 283 Gr C is used in low-pressure vessels and structures, while SA 516 Gr 70 is for boilers and high-pressure vessels with better toughness. They are not interchangeable due to strength differences. Gangsteel's plates support both with certifications.
