A36 carbon steel Round Bar gives stiffness and strength to projects at a lower cost and is a popular structural steel Round Bar used in a variety of applications and industries compared to other grades. Consider A36 as a starting point. Carbon Steel A36 Round Bar is a popular structural steel Round Bars used in a variety of applications and industries because it gives stiffness and strength to projects at a lower cost than other steel Round Bars grades.
A36 is bolted and nailed in most structural applications, but it can also be welded with shielded metal arc, gas metal arc, or oxyacetylene. One of the notable differences between SA36 and A36 steel is that SA36 has a higher yield strength.
Difference between ASTM A36 and ASME SA36
While ASTM and ASME standards for steel and other metals are quite similar, if not identical, there may be tiny differences between A36 and SA36 grades, depending on the criteria used by the particular organizations. In reality, ASTM A36 and ASME SA36 are the only two standards that exist, ASTM SA36 is not.
For use in bridges and buildings that are riveted, bolted, or welded, as well as for general structural purposes, ASME A36 specifies carbon steel forms, Round Bars, and bars, while the ASME contains design standards for pressure applications. In most cases, ASME regulations are based on ASTM standards, although their numbers are prefixed with the letter ‘SA’ rather than only the letter ‘A’ in ASTM regulations.
A material is designated An A or SA depending on whether it is accredited by the ASME Boiler and Pressure Vessel Code. Materials that are delivered for use in code-fabricated components meet the standard of ASME Boiler and Pressure Vessel Code, Section II. As an A designation, a material is compliant with the weaker ASTM A36 standards – it typically meets the same or similar specifications, but has not been recognized by ASME regarding boilers and pressure vessels.
SA36 may be used in projects that require A36, but ASTM A36 cannot be used in projects requiring ASME Boiler and Pressure Vessel Code approval. To put it another way, A36 and SA36 may be similar, but SA36 may not be permitted to be used when creating code.
