AH36 hull structure steel standard for carbon steel plate

SA517GrQ material is a high-strength quenched and tempered alloy steel plate, which belongs to the steel for offshore oil drilling racks. The upper limit of SA517GrQ steel plate thickness is 150mm, and the upper limit of rack steel is 177.8mm. BBN STEEL has opened up a new heat treatment process route for the 177.8mm thick offshore platform rack steel A517GrQ, and strives to improve the production capacity of this product.

Based on the main AH36 hull structure steel business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel AH36 hull structure steel products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the AH36 hull structure steel steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of AH36 hull structure steel extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in AH36 hull structure steel steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of AH36 hull structure steel steel.
