How to protect EN 10025-6 high strength steel 1.8988 from crack

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in EN 10025-6 high strength steel 1.8988 etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

Today, the prices of black commodity futures market fluctuated upward. The mentality of the spot market is optimistic, and the quotations of EN 10025-6 high strength steel 1.8988 merchants continue to rise. However, downstream users are more cautious in purchasing, and they basically purchase on demand. Some speculative demands have the willingness to replenish at low prices. At present, there are relatively few EN 10025-6 high strength steel 1.8988 inventory resources in the market. In addition, the cost of resources in the later stage is relatively high, so businesses are not willing to sell at low prices. On the whole, there are not many short-term new arrival resources, and the shipping pressure of merchants is not big, and the EN 10025-6 high strength steel 1.8988 price still has certain support. It is expected that the price of EN 10025-6 high strength steel 1.8988 will fluctuate and be stronger tomorrow.
