For the estimation in April and the second quarter, the estimation on March 16 is still valid, but the decrease in April is 10% higher than the neutral prediction. It is a conservative estimation based on 10% for the high probability event. In the second quarter, the output of overseas pig iron will be reduced by 11.67 million tons, affecting the demand for A514 grade R alloy steel plate iron ore of about 1.84 million tons; in the first half of the year, the output will be reduced by 18.899 million tons, affecting the demand for iron ore of 32.13 million tons.

Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, A514 grade R alloy steel plate. The main differences according to the classification are as follows: A needs no impact test, B needs room temperature impact test (20 degrees above zero), C needs zero degree impact test, D needs minus 20 degree impact test, and E needs minus 40 degree impact test. The most important characteristic of manganese steel plate is that under the condition of strong impact and extrusion, the surface layer rapidly hardens, but the core still maintains good toughness and plasticity, and the hardened layer has good wear resistance.
A514 grade R alloy steel plate, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., >16-40mm: 345MPa min., >40-60mm: 335MPa min., >60-100mm: 315MPa min., >100-150mm: 295MPa min., >150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.
BBN had provided A514 grade R alloy steel plate Hardox plates for more than 15 years for widely applied in coal mining machinery, cement equipment, road construction machinery, engineering machinery, dump trucks, metallurgical area and port fields. In 2016,we brought our customer to visit our A514 grade R alloy steel plate NM400 steel plate producing line and our Shanghai warehouse for 30000 tons plate and structure. As a result, Our client purchased 500 tons NM 400 as first order, which is shipped by 3 times. In future, BBN will always guarantee that all the delivery condition for Hardox plate provided will be with quenching and tempering, which is the best delivery type according GBT 24186 standard.
