Welcome to BBN High Strength Steels Factory
Shipbuilding steel is a kind of steel plate used by shipyards, shipbuilding companies and dockyards to manufacture hulls of cargo and passenger ships, boats, offshore drilling platforms, gateways and other structures and vessels. The company also supply AB AH36 plates and steel sheets S690QL material specification in coils or cut to length, steel profiles (steel bulb flats, rounds and squares), and round and profiled tubes made from shipbuilding steel grades. Shipbuilding steel is produced under the control of certifying societies, sea and river registers.
The company has S690QL material specification advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience S690QL material specification, we have accumulated a large number of customers at home and abroad, and won unanimous praise.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S690QL material specification are higher than that of annealed S690QL material specification, but the elimination of internal stress is not as good as annealing. The normalizing operation of S690QL material specification is simple, the cost is low, the productivity is high, and it is widely used in actual production.
Sulfur is a very harmful element in {keyword steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of {keyword steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
Our company will accept the product quality objection registration record, pass it to the S690QL material specification production unit and relevant departments, and timely coordinate the supervision of product S690QL material specification quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
