BÖHLER K110 adalah baja kromium ledeburitik 12%, menawarkan kombinasi terbaik antara ketahanan aus, kekuatan tekan, dan ketangguhan, sehingga digunakan di hampir semua aplikasi pekerjaan dingin. Perilaku temperingnya yang menguntungkan dengan kekerasan sekunder maksimum yang nyata juga memungkinkan penggunaan pelapis tingkat lanjut. Hal ini juga membuat BÖHLER K110 cocok untuk perkakas kompleks yang memerlukan stabilitas dimensi dan stabilitas bentuk tingkat tinggi.

BÖHLER K340 ISODUR
BÖHLER K340 ISODUR termasuk dalam kelompok baja kromium 8%. Baja perkakas ini diproduksi menggunakan proses peleburan kembali terak elektro (ESR) yang dikembangkan oleh BÖHLER. Teknologi peleburan ulang ini memastikan segregasi mikro dan makro terendah serta kemurnian dan keseragaman material yang sangat baik. Dibandingkan dengan baja kromium 12% konvensional, BÖHLER K340 ISODUR menawarkan ketangguhan, respons pengerasan, dan ketahanan yang lebih tinggi terhadap keausan perekat yang jauh lebih baik. Oleh karena itu, material ini digunakan di hampir semua aplikasi pekerjaan dingin dalam situasi di mana baja perkakas seperti 1,2379 tidak mencukupi dalam hal ketahanan aus dan ketangguhan perekat. K340 ISODUR juga memiliki kemampuan permesinan yang lebih baik dan mengurangi risiko retak tegangan selama pemesinan pelepasan listrik.>
