JIS G3116 SG325 steel plate

Product Introduction

　　SG325 is hot‑rolled structural steel for gas cylinder manufacturing, specified under JIS G 3116 standard, available in plates, sheets and strips. Compared with SG295, SG325 provides higher elastic region and tensile strength, specially developed for general gas cylinder production.
