Martensitic Stainless Steel 12 Percent Cr Seamless Linepipe

In the development of oil and gas, transportation of CO2 corrosive oil and gas will become an increasingly common occurrence.
To handle this major problem JFE has developed a Martensitic Stainless Steel for lilepipe applications, JFE's Martensitic Stainless Steel 12% Cr.

Features
1. Good weldability as compared with conventional 13% Cr.
2. Excellent toughness in low temperature services
3. Excellent corrosion resistance to CO2 as good as OCTG13CR

Typical application and chemistry design

JFE-12HP1-X80
Light sour condition
LowC-12Cr-5Ni-2Mo
