Kinerja persyaratan dari cetakan baja
Die steel is th type of steel used to make molds such as cold punching dies% 2c hot forging dies, die-casting dies, etc. Mold materials are the material and technical basis of the mold manufacturing industry. Among them, mold steel is the traditional mold material. Its variety, specification and quality play a decisive role in the performance, service life and manufacturing cycle of the mold. In baru-baru ini tahun, the output, produksi teknologi, proses peralatan, kualitas, dan varietas dari cetakan baja at rumah dan luar negeri sudah tercapai relatif cepat pengembangan. Mereka pengembangan dari cetakan baja memiliki juga dipromosikan industri produk untuk menjadi lanjutan, individualisasi, dan tinggi nilai tambah. arah pengembangan. The mold has a wide range of uses, and the materials used to make the mold are very wide. The most widely used mold Bahan adalah Cetakan Baja.
Performa PersyaratanSunting Siaran
1. Anil proses
The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.
2. Forgeability
It has rendah panas penempaan deformasi resistensi% 2c baik plastisitas% 2c lebar penempaan suhu rentang% 2c rendah kecenderungan dari penempaan retak 2c dingin retak dan curah hujan dari jaringan karbida.
3. Sensitivity to oxidation and decarburization
When heated at high temperature, it has good anti-oxidation capacity, slow decarburization speed, insensitive to heating medium, and little pitting tendency.
4. Machinability
5. Hardenability
6. Grindability
7. Hardenability
Setelah pendinginan, it has seragam dan tinggi permukaan kekerasan.
Eight, pendinginan deformasi cracking kecenderungan
The volume change of konvensional quenching is small, the shape is warped, the distortion is slight, and the tendency of abnormal deformation is low. Conventional quenching has low cracking sensitivity and is insensitive to quenching temperature and workpiece shape.
