■ Characteristics of PROVA400 • Good in corrosion resistance due to martensite stainless steel material. • Good for mirror finish due to high cleanliness steel with ultimate reduced non–steel inclusion. • Good in abrasion resistance due to heat treated hardness as 53HRC. • Extremely less in dimensional changes during heat treatment process due to homogenized processing.
E Refer to P.419 for the size larger than φ 16
of the material.
E is a registered trademark of UDDEHOLM TOOL CO. E PROVA400 is equivalent to SUS420J2 upgrading steel from Fujikoshi Co.
