Metallurg & Yalloys
We have developed our own proprietary series of alloys
Based on more than 20 years of experience, Zhejiang Hongfei Machinery Manufacturing Steel has developed our own proprietary series of alloys which exceed the classic ASTM minimum standards. We offer one of the largest selections of wear- and heat-resistant alloys available from any single supplier. That provides many advantages to the end user. For example, we can supply all the various parts needed for a cement plant maintenance shutdown, from quarry to grinding mills to kiln to cooler. By varying the composition and heat treatment of our alloys, we are able to fine tune them, balancing toughness, hardness and/or heat and corrosion resistance for the specific application.
| ALLOY | PROPERTIES | APPLICATIONS |
|---|---|---|
| Austenitic Manganese Steels | Unequaled toughness and good resistance to abrasion is provided by work hardening when service conditions have sufficient impact | Liners for gyratory, cone, and jaw crushers, roll shells, shredder liners, hammers and grates |
| Chromium Molybdenum Steels | Outstanding abrasion resistance within the medium hardness range — grades range from 286 to 600 HB | Rod, ball and semi-autogenous mill liners, cement plant diaphrams, gyratory crusher concaves |
| High Chromium Alloy Irons | Excellent abrasion resistance with improved impact strength and high hardness beyond 650 HB | Rod, ball and semi-autogenous mill liners, coalpulverizers, cement rollermill and cooler parts, VSI parts |
