Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, S355ML grade equivelent based on a high starting point and high technology, the company has vigorously developed various steel products S355ML grade equivelent and deep-processed parts, steel structures, precision castings, seamless pipes.

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel S355ML grade equivelent can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

API 5CT N80 casing pipe is important equipment for oil drilling . API 5CT N80 casing pipe main application is to support the sidewall of the oil well during drilling. API 5CT N80 oil casing pipe plays an important role to guarantee the normal operation of the whole well drilling work.

Generally speaking, the higher the strength of S355ML grade equivelent, weathering steel, the greater the hardness, while the plasticity and toughness will decrease. When the carbon content of weathering steel exceeds 1.2%, the hardness will increase, but the strength will not increase, but will decrease. Resilience will also decline quickly. When the carbon content is high, the cementite increases and forms network distribution, which weakens the connection between grains and makes the mechanical properties of steel worse.
