In recent years, in line with the development trend of iron and steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
The company has a group of mature steel plate production and processing line construction and production management experience In addition, the company has professional and technical personnel BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team At the same time, it also adheres to international standards and adheres to the international line,A514 Gr E structural steel.
Weathering steel plate is a kind of natural weathering steel plate with atmospheric corrosion resistance, characteristic corrosion and oxidation, which has been obtained in many fields. The common basic properties and the state of various weathering steel plates have been well reflected in the construction. At present, it is mainly used for welding and manufacturing of traffic vehicles, construction machinery, bridges, towers, containers, steel containers and other low alloy structural steel. Features: strong toughness, rust resistance, corrosion resistance, thinning and consumption reduction, energy saving.
The hot rolling method is to heat the 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 rolling process is usually called semi-finished product production, also called blank production.A514 Gr E structural steel

The Steel Quality Had Been Get Customers’Praise."
The final heat treatment of quenched and tempered alloy steel is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
