Heat treatment of chemical composition of hardox 400 steel

The effect of nitrogen (N) on the properties of chemical composition of HARDOX 400 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 chemical composition of HARDOX 400 and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

Steel pipe refers to the steel with openings at both ends and hollow section, and its length is larger than that of surrounding steel. According to the processing technology, it can be divided into seamless steel pipe and welded steel pipe, chemical composition of HARDOX 400. The production methods mainly include hot rolling, cold rolling, extrusion, cold drawing, forging, welding, etc. The size range of steel pipe is very wide, from capillary with small diameter to large diameter pipe with several meters. Steel pipe can be used for pipeline, thermal equipment, mechanical industry, petroleum geological exploration, container, chemical industry and special purpose.

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing chemical composition of HARDOX 400 high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

The cultural construction must let the enterprise staff participate in the enterprise culture, in order to better carry on the effective dissemination enterprise idea, the sharing value system, such as the internal communication, the newspaper, the forum, the propaganda, the news announcement and so on. At the same time, the system can also be used to educate and train employees, send blessings to employees on their birthdays or during Chinese New Year holidays, so that employees can feel the practice of corporate culture, the warmth of the enterprise, and enhance the sense of belonging and recognition of the enterprise.
