  • HC-001 
  • Nanjing 
  • Screw 

    The so-called duplex stainless steel is the ferrite phase and the austenite phase account for about half of each in its solid solution structure,and the content of the small amount of phase generally needs to reach 30%。In the case of low C content,Cr content is 18% -28%,Ni content is 3% -10%。Some steels also contain Mo、Cu、Nb、Ti、N and other alloying elements。
