Baja Mangan Karbon Tinggi
Baja Mangan Karbon Tinggi adalah a high-performance wear-resistant steel with carefully balanced komposisi kimia dan sifat mekanik. It is widely used to produce liner penghancur, liner pabrik penggilingan, liner ember, and other high-impact, abrasion-resistant components, menyediakan superior durability, kekerasan, and cost-effective long-term performance di pertambangan, konstruksi, semen, dan aplikasi industri berat.
- Keterangan
Baja Mangan Karbon Tinggi (HCMS), juga dikenal sebagai baja mangan tinggi, adalah sebuah austenitik, baja tahan aus banyak digunakan di aplikasi tugas berat. Kombinasi dari high carbon and high manganese content menyediakan ketahanan aus yang luar biasa, kemampuan pengerasan kerja yang kuat, and superior toughness, menjadikannya ideal untuk impact-intensive environments misalnya pertambangan, penghancur, dan mesin pemindah tanah.
Komposisi Kimia
Itu typical chemical composition of high carbon manganese steel is designed to achieve maximum wear resistance and toughness:
| Elemen | Kisaran Khas (% berat) | Fungsi |
|---|---|---|
| Karbon (C) | 1.0 – 1.4 | Provides surface hardness and work-hardening capability |
| mangan (M N) | 11 – 14 | Stabilisasi austenit, kekerasan, ketahanan terhadap abrasi |
| Silikon (Dan) | ≤ 1.0 | Deoxidation and strength enhancement |
| Fosfor (P) | ≤ 0.07 | Kontrol pengotor |
| Sulfur (S) | ≤ 0.03 | Kontrol pengotor |
| Kromium (Kr) | ≤ 2.0 | Meningkatkan kekerasan dan ketahanan aus |
| Nikel (Di dalam) | ≤ 1.0 | Meningkatkan ketangguhan |
| Besi (Fe) | Keseimbangan | Logam dasar |
Kinerja Mekanis
High carbon manganese steel combines ductility and hardness through its perilaku pengerasan kerja:
| Milik | Nilai Khas |
|---|---|
| Kekuatan Hasil | 350 – 450 MPa |
| Kekuatan Tarik | 750 – 1100 MPa |
| Pemanjangan | ≥ 30% |
| Kekerasan (solusi diperlakukan) | 180 – 220 HB |
| Kekerasan (pekerjaan menjadi keras) | Hingga 500 HB |
Fitur Utama:
-
Tinggi ketangguhan dampak for shock-resistant applications
-
Kuat pengerasan kerja for enhanced wear resistance
-
Non-magnetik dalam kondisi yang diolah dengan larutan
-
Durable under heavy abrasion and repeated impacts
Common Wear-Resistant Finished Products
High carbon manganese steel is processed into various wear-resistant finished components, depending on industrial requirements:
-
Crusher Liners: Pelat rahang, cone liners, pelat tumbukan
-
Grinding Mill Liners: Ball mill liners, SAG mill liners
-
Earth-Moving Components: Lapisan ember, gigi sekop, dipper edges
-
Chutes and Hoppers: Liners for handling abrasive materials
-
Heavy Machinery Parts: Slag plates, layar, and impact plates
These components rely on surface hardening under impact, where the steel’s work-hardened layer protects the component while maintaining a tough, inti ulet, significantly extending service life.
