astm a588 vs astm a242 main useage

09CuPCrNi-A steel belongs to weathering steel. Through alloying of Cu, Mn, Si, Al and simply adjusting part of element content of ordinary low carbon steel (Q235 steel), economic weathering astm a588 vs astm a242 steel with good atmospheric corrosion resistance and comprehensive mechanical properties can be produced without changing the production process of Q235 steel. 09CuPCrNi-A steel is mainly used for railway, vehicle, bridge, tower and other steel structures exposed to the atmosphere for a long time.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, astm a588 vs astm a242 based on a high starting point and high technology, the company has vigorously developed various steel products astm a588 vs astm a242 and deep-processed parts, steel structures, precision castings, seamless pipes.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like astm a588 vs astm a242, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

Oxygen is a harmful element in astm a588 vs astm a242 steel. With the increase of oxygen content, the strength of astm a588 vs astm a242 steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of astm a588 vs astm a242 steel.
