Standard and super high grades are the two types of grades used in the steel industry. The most prevalent kind of steel plate is a standard grade, which is created from a combination of iron, silicon, and carbon, the same elements that make up everything around you. Choosing an ultra-high quality grade will, however, make your steel stronger and more resilient. Since only iron and carbon are used to create these plates, they are lighter and less expensive than regular grades.
Difference Between SA516 Grade 70 Plate and SA516 Grade 60 Plate
The point of this discussion is not to discuss grades, you might ask, but to explain why we are talking about grades. For your upcoming project or business venture, you should keep in mind the higher tensile strength of the SA516 GR.60 Steel Plate as compared to its counterpart SA516 Gr.70 Steel Plate. It is stronger and can support a greater amount of weight before breaking.
An iron, chromium, nickel, and molybdenum alloy with a yield strength of 70,000 psi is used to make A516 GR.70 steel plates. It is employed in various sectors of the building industry, most notably the auto sector. Iron, chromium, nickel, and manganese alloy with the yield strength of 60,000 psi is used to make A516 GR.60 steel plate. Due to its high tensile strength, immunity to corrosion, and weldability (it can withstand temperatures of up to 2200°F), it is also employed in the construction sector.
As a result of its high chromium concentration and low carbon content, A516 GR.70 steel plate is perfect for use in engines and other high-pressure or severe applications.
A516 GR.60 has higher carbon content than A516 GR.70 and has lower chromium content than A516 GR.70; it is, therefore, less resistant to corrosion than A516 GR.70 but still offers good resistance to oxidation when exposed to air at atmospheric pressure (approximately 14 psi).
Applications of A516 Gr.70 Steel Plate and A516 GR.60 Steel Plate
GR.70 A516 Steel Plate
One of the most popular grades of high-strength low-alloy steel used in construction is A516 GR.70 steel plate. Boilers, heat exchangers, pressure vessels, boilers, and furnaces are the main applications for A516 GR.70 steel. Additionally, it possesses outstanding toughness qualities, good toughness characteristics, and good oxidation resistance, wears, and corrosion.
GR.60 A516 Steel Plate
Due to its high strength and excellent ductility qualities, A516 GR.60 steel plate is a type of low-alloy grade steel that is frequently used in boiler building. Boilers, heat exchangers, and pressure vessels are the main applications for A516 GR.60 steel, which also offers good resistance to oxidation, wear, and corrosion as well as toughness and outstanding toughness properties.
