304 Mack

The flat steel SUS304 is used for drilling frequently as the material for installing the watertight rubber for hoisting rack of the flood gate opening/closing equipment of the screen river for the intake tower of the dam and other various kinds of equipment and devices.

Daido Steel has developed “304 Mack” flat steel in which drilling workability is improved.

Features

The Chemical Composition and Mechanical Properties are the same as SUS304 of JIS, so it can be used as SUS304 itself.
The “304 Mack” is excellent in drilling life compared with ordinary SUS304.
