ASTM A573 Grade70 Carbon Steel A573Gr70 Boiler Steel

ASTM A573 Grade 70 Carbon steel plates

ASTM A573 Grade 70 Carbon steel plates are widely used materials for industrial structures such as buildings, ships and bridges. ASTM A573 gr70 carbon steel has excellent notch toughness and weldability, making it an ideal choice for pressure vessels and boilers. A573gr70 carbon steel is heat-treated and contains manganese, phosphorus, sulfur and silicon, ensuring the material is fully hot-rolled and highly durable. The material is designed to be used at high temperature or in extreme pressure situations and is able to stand up to the task.

The carbon content in ASTM A573Gr70 carbon steel is usually around 0.2%, with a range from 0.15 - 0.25% to ensure the strength and ductility of the material. Its low carbon content also makes it more resistant to corrosion compared to other boiler steel plates, making it a great choice for tanks and pressure vessels. A573 grade 70 steel has an excellent combination of strength and ductility, making it highly resilient for various applications.

The mechanical properties of ASTM A573 grade 70 carbon steel include its yield strength, which ceiling is round 450MPa; its tensile strength, which is round 585-760MPa; and its elongation, which is round 18%. Furthermore, its hardness varies between 171-229 Brinell (HB) and a Charpy impact value of around 28J at 0°C.

A573 Grade 70 carbon boiler steel is often used in boiler construction, bridge construction, shipbuilding, and a variety of other construction applications. As it is heat-treated and quenched, it can be formed and bent easily to the desired shape. This makes ASTM A573 grade 70 carbon steel an ideal choice for pressure vessels and boilers.
