ABS DH36 Steel Plate Supplier

ABS-certified material serves the shipbuilding industry with some of the most high-performance steel available, with properties optimized to meet all the challenges associated with shipbuilding and offshore fabrication projects. GNEE Steel carries a full inventory of the H-series shipbuilding steels, including AH36, EH36, and DH36 in the most widely used formats.

DH36 steel is designed to resist the harsh saline conditions of marine environments, and DH36 steel plate is typically employed for fabricating ship’s hulls, bulkheads, upper decks and hatch covers. DH36 steel contains elements such as Nb, V, Ti, and other alloying metals, and micro-alloying technology is used to enhance its mechanical properties. The controlled rolling process refines the grain of the alloy, and improves durability. Simply put, the H series of shipbuilding-grade plate offers some of the highest performance steel in the world.

FAQ

Q:Why don’t steel ships rust?

A:Steel ships are protected from rust by coatings, such as paint, and cathodic protection systems that prevent corrosion.

Q:What steel is used in shipbuilding?

A:Shipbuilding primarily uses high-strength low-alloy steels, including grades like AH36, DH36, and EH36.

Q:What grade of steel is used in shipbuilding?

A:Common grades used in shipbuilding are AH36, DH36, and EH36.

Q:What is the difference between EH36 and DH36 steel?

A:EH36 steel has higher strength and toughness compared to DH36 steel, making it suitable for more demanding applications.

Q:What is the steel grade DH36 equivalent to?

A:DH36 steel is equivalent to ASTM A131 Grade DH36 and can be compared to other international standards like ABS Grade DH36.

Q:What does ABS stand for?

A:It stands for American Bureau of Shipping and indicates that the grade was certified by the Bureau.

Q:What is the difference between ABS A/B and ABS AH36/DH36/EH36/FH36?

A:Ordinary-strength steel comes in a various number of grades, including A, B, D, E, and F. Each of these grades have different alloy chemical ingredients and a different fracture toughness.
