More Details About Each Heavy Steel Plate Grade

  • A36

    A36 is a very popular carbon steel common in structural applications. It has excellent strength, formability, and welding properties, and is suitable for a wide range of applications like welding, fabricating, and bending. You will frequently find A36 in construction and structural fabrications. Due to its wide variety of uses, Kloeckner Metals routinely stocks it in a large variety of thicknesses, widths, and lengths.

  • A572

    A572 is a high-strength, low-alloy steel that is common in applications requiring more strength per unit weight. Compared to regular carbon steels, you’ll need less A572 to meet your strength requirements. A572 is common in structural applications and Kloeckner Metals supplies it in thicknesses of 3″ to 6″ and a wide range of widths and lengths.

  • A516

    A516 is a medium carbon alloy plate that’s typically used in pressure vessels where notch toughness is a requirement. A516 is found in low and moderate temperature applications. It is sometimes called PVQ516. It comes in a number of grades, including 55, 60, 65, and 70.

  • A514

    A514 steel plate is known for its toughness, weldability, and high yield strength. It is a high-value plate that’s high performing in structural and high-wear machine applications. The primary use for A514 is for structural steel in the construction of buildings.

  • A709

    A709 is a common steel plate grade that’s commonly used in the manufacturing of bridges. It is available as heavy plate throughout Kloeckner’s distribution network at thicknesses of up to 4 inches.

  • C1020

    C1020 steel plate is usually machined into parts that are typical in a range of markets, most commonly heavy truck, agricultural equipment, and automotive. Parts can include worm gears, ratchets, shafts, axles, and more. With good weldability and formability, 1020 steel has improved machinability because of its controlled carbon range.

  • 4140

    4140 alloy steel plate has an excellent strength-to-weight ratio. While it’s much stronger and harder than 1020 steel plate, it isn’t easily welded and needs heat treatment before and after welding to avoid cracking. You’ll typically find 4140 in rams, couplings, stubs, fixtures, and more.
