This marks the first order for NSCarbolex™ Neutral duplex stainless steel pipes by Nippon Steel.
NSCarbolex™ Neutral employs a “mass balance approach”, allocating a portion of greenhouse gas (GHG) emissions savings—such as CO₂ reductions achieved through Nippon Steel’s internal decarbonization projects—to specific steel products. The company has obtained a limited third‑party assurance and issues certificates confirming the GHG reduction allocations. These certified savings can be claimed by customers as reductions in their Scope 3 emissions and upstream emissions at the product level.
HH Stainless, with over 30 years of experience supplying stainless steel for sectors including petrochemical, construction, marine, and offshore industries, aligned its vision of “Sustainability For The Next Generation” with Nippon Steel’s carbon-neutral ambition.
As global demand for decarbonization grows, Nippon Steel says it will continue collaborating with HH Stainless and other partners to expand the supply of NSCarbolex™ Neutral and contribute to a carbon-neutral society.
