On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported a573 grade 70 and sa709 grade 50 steel comparison more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make a573 grade 70 and sa709 grade 50 steel comparison persistent efforts and forge ahead.
The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)
We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the a573 grade 70 and sa709 grade 50 steel comparison steel pipes. And do PT, MT and so on tests for the pipe fittings. We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.
Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the a573 grade 70 and sa709 grade 50 steel comparison steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of a573 grade 70 and sa709 grade 50 steel comparison seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
Corrosion resistant steel is a kind of steel which can resist corrosion in air or weak medium and other strong corrosive medium. Corrosion resistant steel is also a kind of stainless steel. The corrosion resistance of corrosion resistant steel is better than that of stainless steel. a573 grade 70 and sa709 grade 50 steel comparison, Corrosion resistant steel has good machinability and high corrosion resistance in normal indoor environment. In the project, it can be used for its good corrosion resistance, and can be cut into steel with desired shape at will.
In order to better develop the international steel market and make the steel products trade more prosperous at home and abroad, the company has a number of professional talents who love their posts and are proficient in their business. The company has always been adhering to the "service first, reputation first, customer first, make friends" business purpose, is willing to work together with domestic and foreign customers!
