Ringkesan bar Putaran Baja Spring
Bar baja musim semi cocog kanggo macem-macem aplikasi spring kalebu sumber ijo, klambi, lading dokter, alur-agul, gerges, lading, cuci, tukang cuci, tukang cuci. Nalika suhu panas en42 suhu, kalebu tingkat pemanasan, pendinginan lan rendangan, lan sapiturute bakal beda-beda amarga faktor lan ukuran saben komponen. Pertimbangan liyane sajrone proses perawatan panas kalebu jinis tungku, quenching fasilitas transfer medium, lan workpiece. Mangga konsultasi panyedhiya perawatan panas kanggo pandhuan lengkap babagan perawatan panas ing musim semi.
