The A285/A285M-17 steel grade is known for its superior properties in various applications. This steel grade is primarily used in pressure vessel applications where low and intermediate tensile strength is required.
The chemical composition of the A285/A285M-17 steel grade includes carbon, manganese, phosphorus, sulfur, and silicon. The carbon content is kept low to improve weldability and formability, while the manganese content enhances the tensile strength and yield strength of the steel. The addition of phosphorus and sulfur helps in improving the machinability and reducing the occurrence of brittleness. Silicon is also added to improve the strength and ductility of the steel grade.
In terms of mechanical properties, the A285/A285M-17 steel grade offers excellent tensile strength and yield strength. The minimum tensile strength for this steel grade is 310 MPa (45 ksi), while the minimum yield strength is 205 MPa (30 ksi). These properties ensure the structural integrity and reliability of the steel grade in demanding pressure vessel applications.
The A285/A285M-17 steel grade conforms to the ASTM A285/A285M standard, which specifies low and intermediate tensile strength carbon steel plates for pressure vessels. This standard ensures that the steel grade meets specific requirements for chemical composition, mechanical properties, and fabrication considerations.
Overall, the A285/A285M-17 steel grade is highly regarded for its superior properties, including its low and intermediate tensile strength, excellent weldability, formability, and machinability. These properties make it a suitable choice for various pressure vessel applications, ensuring long-lasting performance and safety.
