“Perfect Roof” of High-purity Ferritic Stainless Steel
Applicant:E. KATAYAMA
& CO., LTD.
Reason for selection: Business climate surrounding the construction industry is getting complicated
and varied with soaring materials costs and labor shortage.
The material selection of SUS443J1, a high-purity ferritic grade, for “Perfect
Roof” worked to realize such needs of building designers and owners as
designability, durability and low cost.
SUS443J1 was registered in the 2013 version of “the standard specifications
for public works”, which now enables material suppliers to offer this grade
for both public and private works.
In addition, this nickel-free grade is economical and earth-friendly and
yet has the corrosion resistance equivalent to that of SUS304.The
adoption of SUS443J1 helps satisfy social needs and will contribute to our
society.
