Types of Alloy Steel Sheets
Alloy steel sheets are made by combining different metals, including iron, carbon, and other elements like chromium, nickel, and molybdenum. The resulting alloy steel sheet is stronger and more durable than traditional steel sheets.
Low Alloy Steel Sheets
Low alloy steel plates are one of the most commonly used types of alloy steel sheets. They contain less than 5% alloying elements such as chromium, nickel, or molybdenum. Low alloy steels have excellent strength and toughness but are not as corrosion-resistant as high-alloy steels. These plates are widely used in construction machinery, mining equipment, pressure vessels, and oil rigs.
High Alloy Steel Sheets
High alloy steel plates contain more than 5% of alloying elements such as chromium, nickel or molybdenum. These plates offer superior strength and durability compared to low-alloy steels. High-alloy steels also have excellent resistance to corrosion and wear making them ideal for applications that require high-performance materials such as aerospace components or medical implants.
Aluminum Killed Steel Sheets
Aluminum killed steel sheets have been treated with aluminum to remove any remaining oxygen from the molten metal during production. This process results in a cleaner material that has improved ductility and toughness compared to other types of steel alloys. Aluminum killed steels are commonly used in automotive parts manufacturing due to their ability to be easily formed into complex shapes.
Chromium-Molybdenum Steel Sheets
Chromium-molybdenum (CrMo) is an alloy that contains both chromium and molybdenum which provides exceptional strength at high temperatures along with excellent corrosion resistance properties. Chromium-molybdenum steel sheets are used in the production of boilers, pressure vessels, and other high-temperature applications.
Nickel-Chromium-Molybdenum Steel Sheets
Nickel-chromium-molybdenum (NiCrMo) steel sheets are a type of high-alloy steel that contains nickel, chromium, and molybdenum. These elements provide excellent corrosion resistance properties along with superior strength at elevated temperatures. NiCrMo steels are commonly used in chemical processing plants and oil refineries.
Latest Price Material Grade
The price of alloy steel plates varies depending on the grade and type of material. The latest price material grade for alloy steel sheets is determined by several factors such as the current market demand, availability of raw materials, and production costs. It’s important to consider all these factors when choosing an alloy steel sheet for your specific application.
Alloy Steel Sheet Grades and Standards: ASTM, AISI, and SAE
ASTM Standards
ASTM International is a globally recognized organization that develops and publishes technical standards for various materials, products, systems, and services. ASTM has established several standards that define the chemical composition, mechanical properties, testing methods, and other relevant aspects of different material grades.
One of the most commonly used ASTM standards for alloy steel sheets is A387/A387M. This standard covers chromium-molybdenum alloy steel plates intended primarily for welded boilers and pressure vessels designed for elevated temperature service. The standard includes several material grades such as Grade 2 (Class 2), Grade 12 (Class 2), Grade 11 (Class 2), Grade 22 (Class 1/2), Grade 5 (Class 1/2), among others.
Another widely used ASTM standard is A1011/A1011M. This standard covers hot-rolled carbon steel sheets intended for use in structural applications such as bridges or buildings. However, it also includes provisions for some types of high-strength low-alloy steel sheets.
ASME Standards
The American Society of Mechanical Engineers (ASME) is another organization that establishes standards related to materials used in engineering applications. ASME has developed several codes and standards that cover various aspects of pressure vessel design and construction.
One of the most commonly referenced ASME codes related to alloy steel sheet grades is Section II Part D – Materials Properties. This code provides information on the allowable stresses, tensile and yield strength, and other mechanical properties of different materials used in pressure vessel construction. It includes several material specifications such as SA-387/SA-387M for pressure vessel plates made of alloy steel.
AISI Standards
The American Iron and Steel Institute (AISI) is a trade association that represents the North American steel industry. AISI has developed several standards related to the chemical composition and mechanical properties of different types of steel.
One of the most commonly referenced AISI standards for alloy steel sheet grades is AISI 4140. This standard covers chromium-molybdenum alloy steel that is widely used in various applications such as oil and gas drilling, automotive components, and structural parts. The material is known for its high strength, toughness, and resistance to wear and tear.
