A36, also known as ASTM-A36, is a type of steel under the American standard ASTM with a yield strength of 36KSI (≈250Mpa). Comparing its physical and chemical properties standards with several common types of steel in domestic standards:
Summary of comparison:
1. Because Q235B is resistant to impact, Q235B is used instead of SA36 materials in the steel structure.
2. Q235A, because the material performance cannot meet the pressure container requirements, now Q235A has been banned from being used in pressure vessel manufacturing, which makes it difficult to purchase Q235A on the market. Therefore
Therefore, it is generally recommended to replace A36 with Q235B.
