Aplikasi:
SPCC/SPCCT: Umum & Umum Gunakake; Karakteristik: Cocog kanggo mlengkung Processing lan prasaja Processing drawing jero, punika varieties paling dikarepake; Aplikasi: Kulkas, rel, switchboards, kranjang wesi lan liya-liyane.

SPCD: Drawing & Stamping Gunakake; Karakteristik: Kapindho mung kanggo SPCE, kualitas panyimpangan cilik saka piring baja drawing; Aplikasi: Sasis mobil, gendheng lan liya-liyane.

SPCE/SPCF: Drawing jero & Stamping Gunakake; Karakteristik: Gandum wis diatur, kinerja drawing jero banget, sawise stamping bisa njaluk lumahing ayu. Aplikasi: Fender mobil, panel sisih mburi lan liya-liyane.

SPCG: Ekstra-Jero Drawing & Stamping & Punching Gunakake; Karakteristik: Baja gulung kadhemen karbon sing sithik banget, kemampuan proses gambar sing jero banget. Aplikasi: Papan interior mobil, permukaan lan liya-liyane.

Cathetan: SPCCT minangka pangguna sing nemtokake kelas SPCC sing kudu mesthekake yen kekuatan tarik lan ekstensibilitas spesies kasebut. SPCF, SPCG kudu mesthekake yen ana non-tuwa (ora amarga kedadeyan deformasi tensile saka properti), sawise njaba pabrik kanggo 6 sasi - yaiku, SPCC, SPCD, SPCE yen disimpen kanggo dangu, bakal gawé owah-owahan kinerja mechanical, utamané kanggo ngurangi kinerja stamping kadhemen, iku kudu digunakake sanalika bisa.

Katalog seri SPCC kudu nggawe pranata kanggo kekerasan lan lumahing sadurunge nalika pesen.

lumahing:
FB: lumahing finishing luwih: Ora mengaruhi formability lan nutupi, plating cacat adhesion, kayata umpluk cilik, goresan cilik, muter cilik, rada scratched lan werna oxidized diijini ana.

FC: finishing lumahing majeng: Sisih luwih saka piring baja kudu luwih winates kanggo cacat, ora ana cacat katon ketok, sisih liyane kudu ketemu syarat lumahing FB.

FD: finishing lumahing ekstra-majeng: Sisih luwih saka piring baja kudu luwih winates kanggo cacat, sing, ora mengaruhi tampilan Paint utawa sawise kualitas plating, sisih liyane kudu ketemu syarat lumahing FB.
