STAINLESS SEAMLESS & WELDED PIPE

Kobayashi Steel Corporation has developed entire range in stainless steel as a material that offers good CO2 gas corrosion resistance, as well as lower cost than duplex stainless steel. Taking advantage of our excellent steelmaking technology to reduce the amount of C and N, improve weldability, and fine-tune alloy composition, we have successfully developed seamless stainless steel pipe for pipelines that features outstanding weldability and corrosion resistance.

Size: Seamless - 1/4" to 24" NB (THK SCH 5 to XXS).
      Welded - 1" to 42" NB (THK SCH 5 to XXS).
