Delivery status: Hot-rolled A514 Gr E high strength steel plate steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.
Chromium element (Cr element) can improve the strength and hardness of A514 Gr E high strength steel plate, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
India began to implement the national blockade measures on March 25. After two extensions, the national blockade measures have been implemented for nearly 50 days, which has a huge impact on the A514 Gr E high strength steel plate economy. To that end, modi said in a televised speech on the evening of the 12th that India will launch a total of 20 trillion Indian rupees one point eight eight Trillion yuan).
