Low alloy steel with 0.12–0.20% carbon, 0.60–0.90% manganese, 0.25–0.60% molybdenum, and 0.40–0.90% chromium makes up ASTM A204 Grade B sheets and plates. Strength, durability, and resistance to corrosion and high temperatures are all improved by this well-balanced composition. The mechanical characteristics include an elongation range of 20–22%, a yield strength of 205 MPa, and a tensile strength of 415–550 MPa. Because of these qualities, ASTM A204 Grade B is perfect for high-temperature and pressure-bearing settings in crucial industrial processes. It also has outstanding weldability and thermal stability.
