BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our A514 grade Q structural steel material office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase A514 grade Q structural steel material 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of A514 grade Q structural steel material, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron A514 grade Q structural steel material production excluding China was 36.309 million tons, a year-on-year decrease of 11%.
According to the new report of the World Steel Association (worldsteel), the world crude steel production for the 64 countries has reached to143.3 million tonnes (Mt) in February 2020, a 2.8% increase compared to February 2019. China’s A514 grade Q structural steel material, crude steel production for February 2020 was 74.8 Mt, an increase of 5.0% compared to February 2019. India produced 9.6 Mt of crude steel in February 2020, up 1.5% on February 2019. Japan produced 7.9 Mt of crude steel in February 2020, up 2.2% on February 2019.
