Installation and Function

Materials and Mechanical Properties

Material and Design Considerations

• Identify material hardness, particle size, abrasiveness, moisture, temperature, pH, impact and tramp material;
• High hardness does not replace core toughness, fatigue strength, corrosion resistance or high-temperature performance;
• For composite, hardfaced, ceramic and elastomer designs, assess substrate bonding, edge protection, fastening and maintainability;
• For parts that mate with shafts, gears, seals, roll surfaces or housings, control fits, tolerances, surface finish and assembly clearances together;
• Assess material upgrades using cumulative throughput, dimensional wear, failure modes, product quality and downtime costs.

Required Ordering / RFQ Information

• Equipment manufacturer, machine model, serial number, part number 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;
