Pelat baja paduan terutama terdiri dari bahan selain karbon dan besi ditambah elemen paduan, seperti tembaga, mangan, aluminium, titanium, tanah jarang dan bahan lainnya.
Lembaran baja paduan memiliki kekuatan tinggi, dan memiliki ketahanan korosi yang baik, ketahanan suhu tinggi dan rendah, ketahanan aus dan sifat non-magnetik. Pelat baja paduan banyak digunakan dalam produksi industri dan konstruksi.
Proses utama pelat baja paduan adalah: pelat baja paduan canai panas, pelat baja paduan canai dingin.
Lembaran baja paduan juga memiliki kemampuan mesin dan kemampuan las yang baik. Penambahan elemen paduan dapat meningkatkan plastisitas dan machinability baja, sehingga memudahkan proses seperti pemotongan, stamping, pembengkokan dan pengelasan.
