“Classically, steel is defined as an iron-carbon alloy with about 2% of carbon. Alloys with greater amounts of carbon have lower melting point and are suitable for casting, being referred to as cast iron. The addition of other alloy elements changes this limit, so a definition based on this limit of chemical composition should only be limited to the so-called ‘carbon steel’.” (Book: Metallography [Metalografia], chapter 2, page 10)

Thick and Extra Heavy Plates

Largely used in capital goods industries, they meet different project requirements and specifications in the most varied segments, such as hydropower, oil and gas, pulp and paper, off-shore, wind power, tooling, metal construction, sugarcane, mining, steel, among others.

At Açobril, we keep a comprehensive stock of 6- to 450-mm-heavy and extra heavy plates of several sizes according to the project.

• ASTM A-36 |ASTM A-515 / 516 | ASTM A-283 / 285 | ASTM A-572 GRAU 50 | ASTM A-131 AH, DH, EH

• SAE 1045 | USI SAR 50 / 60 / 80 | USI SAC 300 / 350 | USI AR 50

• DIN EN 10025 S235, S275, S355 | HARDOX 400 / 450 / 500 among others..

We perform Technological Tests (Tensile Strength, Hardness, Ultrasound, Necking Z25/35, Micro and Macrography, Charpy, Chemical Composition, among others) in accredited Labs, ensuring compliance with the different requirements of each project in a quick and safe manner.

We count on a safe and efficient traceability system, ensuring total safety to our clients.

Our stock, from major Steel Mills, is certified and ultra-sounded, speeding the required acquisition and inspection processes.
