Karakteristik Mild Steel

Pelat mild steel A36, yang juga dikenal sebagai SS400 JIS 3101, di ASME Kode Bagian II-A spesifikasi JIS dari pelat baja untuk konstruksi umum termasuk dalam kategori SA-36. Di JIS (Standar Industri Jepang) “SS” singkatan dari baja struktural (structural steel) dan grade 400 yang mirip dengan AISI 1018. Plat kapal mild steel A-36 adalah salah satu baja canai panas struktural yang paling umum digunakan. Tipikal material baja karbon khas, harganya relatif murah, sangat bagus di las dan di machining dan material baja SS400 dapat mengalami berbagai perlakuan panas.
Baja SS400 pelat umumnya disebut dengan plat mild steel (MS). Untuk plat ukuran 5 x 20kaki (feet) sering juga disebut dengan pelat kapal, karena banyak digunakan untuk industri perkapalan
