Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Hammers
Hinged striking consumable: single-material local harden / compound cast / high-Cr bimetal families—no fixed grade, hardness or life.
Hammer / Swing Hammer is pin-mounted and strikes/throws feed. Verified routes include HAZEMAG single-material local hardening, gen-2/3 compound casting, and CPC high-Cr bimetal beaters; McLanahan optional tip vs bullhead. RFQ by rotor type, rotation, mass group and interface—no invented grades, zone hardness, scrap mm or fixed life. See Hammer Crusher boundaries.
Location and Function
| Material Options | Alloy steel forgings using grades covered by ASTM A322, high-manganese steel, martensitic wear-resistant steel, a high-chromium working layer, or a bimetallic design combining a tough shank and wear-resistant hammer head |
| Typical Properties and Acceptance Criteria | Select hammers for impact, abrasion and tramp-material risk. High-manganese steel commonly starts around 180–240 HB and relies on impact work-hardening. Martensitic steel can balance hardness and toughness around 40–55 HRC. High-chromium working layers are commonly around 55–65 HRC and suit highly abrasive zones only where impact is controlled. Bimetallic hammers must retain toughness at the bore and shank. Verify interface bonding, composition, heat treatment, hardness gradients, UT/MT and individual mass. |
| Principal Failure Mechanism | Impact, cutting and abrasion |
Information Required for RFQ
- Equipment manufacturer, machine model, serial number, model details and latest drawing revision;
- Part dimensions, unit weight, key tolerances, assembly and fastening method;
- Current material, chemical composition, heat treatment, hardness and mechanical property reports;
- Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
- Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
- Failure photographs, wear measurements, crack/fracture locations and current service life;
Stop fields: grade/hardness/bond/scrap size/life.
