What are Steel Plates?
Steel plates are flat sheets of metal that have a thickness ranging from 3/16 inch to 6 inches. They are made of iron alloyed with carbon and other elements to improve its strength, hardness, and corrosion resistance. Steel plates are classified into different grades based on their chemical composition, mechanical properties, and applications.
Some of the most common steel plate grades are:
- A36: A low-carbon steel plate that is suitable for general structural purposes. It has a minimum yield strength of 36,000 psi and can be easily welded and machined.
- A572: A high-strength low-alloy steel plate that is used for bridges, buildings, and other structural applications. It has a minimum yield strength of 50,000 psi and can resist atmospheric corrosion.
- A516: A pressure vessel quality steel plate that is used for boilers, tanks, and other pressure-containing equipment. It has a minimum yield strength of 38,000 psi and can withstand high temperatures.
- T1: A quenched and tempered alloy steel plate that is used for abrasion-resistant applications. It has a minimum yield strength of 100,000 psi and can resist wear and impact.
Depending on your project requirements, you may need to choose a specific grade of steel plate that meets the standards and specifications of your industry. You can also find custom-made steel plates that have special features such as galvanized coating, diamond pattern, perforated holes, or expanded mesh.
