| Brand | SeAH Changwon Integrated Special Steel (SeAH CSS) |
| Category | Tool & Mold Steel → Precision / High-Gloss Mold Steel |
| Country Origin | South Korea |
| Material | Tool steel refined for exceptional purity (e.g. ESR grade in some variants) to minimize non-metal inclusions and enable superior finish & properties. /High polishability, excellent surface finish (mirror / high gloss), weldability, good machinability. Tempers / hardness in the SMAT variants are relatively high (e.g. ~ HRc 37-55 for different SMAT levels) depending on finish & use case. |
| Applications | High-gloss / precision plastic molds, especially for parts requiring optical clarity or premium appearance (e.g. transparent lenses for automotive lamps, TV front bezels, other molded cosmetics / electronics) where surface finish, gloss and precision are critical. |
The SMAT Series from SeAH CSS is a line of premium precision mold steels designed for the most demanding applications in mold making. Variants like SMAT E, SMAT F, SMAT G, and SMAT V deliver superior finish (mirror, high gloss), excellent weldability, and tightly controlled microstructure, often using ESR or similar refining technologies. These steels are ideal for applications where surface appearance and clarity matter — such as transparent lenses for automotive lamps, TV/consumer electronics front bezels, decorative parts, or any molded plastic requiring fine polish and consistent gloss. Thanks to SeAH’s advanced melting, refining, rolling and polishing processes, SMAT steels combine high hardness, tight dimensional stability, and premium surface quality to meet both functional and aesthetic demands.
