The cold working performance of 150mm GL-FH 40 hull structural steel and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of 150mm GL-FH 40 hull structural steel and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
One person familiar with the situation said Germany's ailing ThyssenKrupp Group was in talks with its international counterparts to merge its loss making 150mm GL-FH 40 hull structural steel steel business. The talks will be announced Monday as part of a strategic reform that could include closing or selling assets. Previously, ThyssenKrupp steel Europe, Germany's largest steelmaker, announced a loss in the first half of the group three point seven two 100 million euros four point zero two Billion US dollars). ThyssenKrupp has continued to advocate the benefits of 150mm GL-FH 40 hull structural steel steel integration since it abandoned its joint venture with Tata Steel a year ago to sell its precious elevator division.
As the thickness and hardness of 150mm GL-FH 40 hull structural steel increase, the tendency to crack at the cutting edge increases. In order to prevent the 150mm GL-FH 40 hull structural steel from cutting cracks, preheating should be carried out before 150mm GL-FH 40 hull structural steel cutting. Special attention should be paid to preheating to make the entire 150mm GL-FH 40 hull structural steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole 150mm GL-FH 40 hull structural steel cannot be preheated, the partial preheating method can be used instead.
