The A299/A299M-17 steel grade is a standard specification for pressure vessel plates, carbon steel, manganese-silicon. It is commonly used in the construction of tanks and boilers for various applications in industries such as petroleum, chemical, and power generation.
The chemical composition of A299/A299M-17 steel grade is as follows:
– Carbon (C): maximum 0.28%
– Manganese (Mn): 0.90-1.40%
– Silicon (Si): 0.15-0.40%
These elements provide the necessary strength and toughness required for pressure vessel applications. The manganese-silicon combination enhances the overall mechanical properties of the steel grade.
The mechanical properties of A299/A299M-17 steel grade include:
– Tensile strength: minimum 515-690 MPa
– Yield strength: minimum 310 MPa
– Elongation: minimum 19%
– Reduction of area: minimum 35%
These mechanical properties ensure the steel grade can withstand high pressure and temperature conditions, making it suitable for use in pressure vessels.
The standard number for the A299/A299M-17 steel grade is ASTM A299/A299M. This standard specification provides guidelines and requirements for the chemical composition, mechanical properties, and other relevant details for the steel grade.
In summary, the A299/A299M-17 steel grade is a versatile and strong material that is commonly used in the construction of pressure vessels. Its chemical composition and mechanical properties make it suitable for various industrial applications that require high strength and resistance to pressure and heat.
