Main business: carbon steel plate cutting, round steel cutting, stainless steel cutting, round pipe cutting, A514 grade F alloy steel plate, steel structure welding. It can also cut various machine tool side plates, special-shaped parts, flanges, bearing seats, bearing supporting bases, embedded parts, counterweights, rolling stands, cutting squares, cutting circles, etc. according to customer drawings. BBNsteel company has good business channels with major steel mills, and undertakes all kinds of steel plate processing services.
A514 Gr Q plate is a high strength weldable quenched and tempered steel plate according to ASTM standard. A514 grade F alloy steel plate, A514 Gr Q plate is mainly used in places requiring high tensile strength and high yield. A514 Gr Q or A514 Gr Q modified are generally used for lifting gear of engineering vehicle and rack of offshore platform. It varies with thickness. Its hardness is 235-290, yield is more than 630MPa, and tensile strength is more than 700MPa.
After more than 20 years of ups and downs in the steel industry, BBN company's customers have covered South America, North America, Europe, Africa, Southeast Asia and the Middle East and other countries and regions. We treat every customer who inquires with us sincerely, whether you cooperate with us or not, we will provide you with the best quality steel solutions. Our company team also support the online customer service.
The effect of nitrogen (N) on the properties of A514 grade F alloy steel plate 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 A514 grade F alloy steel plate and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
