Nippon Steel Corporation (Nippon Steel) is proud to announce that our low CO₂ steel product “NSCarbolex™ Neutral” ^*1 will be used for a high-performance product (Torsia-type ultra-high strength bolt SHTB™) by Nittetsu Bolten Corporation^*2 (Nittetsu Bolten). With this, Nittetsu Bolten will expand its lineup of environmentally friendly products in addition to its existing products and will start selling these products in response to customer requests in the future.

Nittetsu Bolten 's "Torsia Type Super High Strength Bolt SHTB" is approximately 1.5 times stronger than the conventional bolt (S10T). This characteristic enables a reduction in the number of bolts during construction and a reduction in the weight of the steel frame due to the reduction in the size of the bracing plate. Together with the benefits of reduced construction man-hours associated with these reductions, the product has also been recognized as a product that can reduce CO₂ emissions from steel frame fabrication to on-site installation.

The adoption of the low-CO₂ steel material "NSCarbolex Neutral" as the material for these ultra-high strength bolts is expected to make them even more environmentally and people-friendly than before.

We will continue to deliver our “NSCarbolex Neutral” and “NSCarbolex Solution” ^*3 to support our customer’s journey towards decarbonization, enhance their competitiveness, and moreover, contribute to the realization of a carbon neutral society.
*3 "Torsia Type Super High Strength Bolt SHTB" is one of the NSCarbolex Solution products.
