What are the influencing factors of flame cutting quality for elongation of hardox 450 steel

BBN had provided elongation of Hardox 450 steel 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 elongation of Hardox 450 steel 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.

What are the characteristics of medium and thick plate, elongation of Hardox 450 steel? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, elongation of Hardox 450 steel is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

Medium and heavy plate is widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. The surface quality of medium and heavy plate mainly refers to its surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plate. The surface quality of elongation of Hardox 450 steel, medium and heavy plate not only affects the appearance of the products, but also reduces the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate.

In March, the daily output of key iron and steel enterprises fell on a month on month basis, while the overall inventory of elongation of Hardox 450 steel and so on steel materials was lower but still at a high level. In terms of production, in March, according to the key statistics, the cumulative average daily output of pig iron, crude steel and steel for iron and steel enterprises was 1.824 million tons, 1.695 million tons and 1.766 million tons respectively, down 2.1%, 3.1% and 1.7% on a month on month basis.
