  Copper (Cu): Wuhan Iron and Steel with Daye steel refining ores often contain copper. Copper can improve the strength and toughness, in particular atmospheric corrosion. The disadvantage is that during thermal processing prone to thermal embrittlement significantly reduces the copper content exceeds 0.5% plastic. When the copper content is less than 0.50% had no effect on weld ability.

  Aluminum (Al): Aluminum is commonly used in steel  Steel was added a small amount of aluminum, can be refined grains, increase the impact toughness, such as deep-drawing steel sheet 08 Al. Aluminum also has anti-oxidation and corrosion resistance, aluminum and chromium, silicon combination, can significantly improve the ability of the skin can not afford high-temperature steels and high temperature corrosion performance. The disadvantage is the effect of aluminum hot work ability of steel, weld ability and  ability.

  Boron (B): Boron steels can be improved by adding small amounts of dense and hot-rolled steel performance, increase strength.

  .Nitrogen (N): Nitrogen can improve the strength of steel, the low temperature toughness and weld ability, increasing aging sensitivity.

  Hebei Shengtian Group Reaguan Pipeline Co.Ltd is mainly produce welded steel pipe and oil pipe. Size is from 1/4” to 140”. Thickness is from sch20 to sch160. Material :Caron steel, ASTM A106 GR.B. ASTM A53, API5l Grb. Stainless steel: 304/304L, 316/316L. And alloy steel pipes.

  Welcome you to join us and seek common development.
