Welcome to BBN High Strength Steels Factory
ASTM A514 steel plate is a high yield strength, quenched and tempered alloy steel plate suitable for welding. A514 steel plate has high strength, and EN 10025-6 high strength steel S460QL1 it can maintain mechanical properties even at very low temperature. At the same time, A514 steel plate also has good fatigue resistance, high toughness and low brittleness transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance.
At the same time, the company operates a variety of products of related iron and EN 10025-6 high strength steel S460QL1 steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained EN 10025-6 high strength steel S460QL1 ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
If the chromium content in EN 10025-6 high strength steel S460QL1 alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
The effect of nitrogen (N) on the properties of EN 10025-6 high strength steel S460QL1 and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in EN 10025-6 high strength steel S460QL1 and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
Our company will accept the product quality objection registration record, pass it to the EN 10025-6 high strength steel S460QL1 production unit and relevant departments, and timely coordinate the supervision of product EN 10025-6 high strength steel S460QL1 quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
