The Ultrasonic flaw detection principle of AH36 ship construction steel plate

BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, AH36 ship construction steel plate plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.

Q355NH material has a protective rust layer that resists atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers, etc. It can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.

The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, AH36 ship construction steel plate. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.

The hot rolling method is to heat the AH36 ship construction steel plate steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of AH36 ship construction steel plate rolling process is usually called semi-finished product production, also called blank production.

JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with AH36 ship construction steel plate SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.

The results of adopting two-level AH36 ship construction steel plate service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and AH36 ship construction steel plate after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
