BBN can provide hot-rolled and cold-rolled steel plates, as well as special processing and cutting (any size and shape) drilling, welding, milling, weather resistant A242 type 2 steel processing and steel structures according to drawings. Welcome new and old customers to purchase steel plate from BBN.

Chromium element (Cr element) can improve the strength and hardness of weather resistant A242 type 2 steel, 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.

Global weather resistant A242 type 2 steel crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global weather resistant A242 type 2 steel crude steel production decreased to 443.03 million mt, down 1.4 percent year on year.
