I. Material Performance Comparison: Manganese Steel Hammer vs. Alloy Steel Hammer
1. Manganese Steel Hammer Head – The Choice for High-Impact Scenarios
● Core Parameters
● Hardness gradient: Initial 45–55 HRC → Impact-hardened to 550 HB
● Alloy Composition: Mn 11-14% + Mo 0.5-1%
● Impact resistance: AKU ≥ 100 J
● Advantageous Scenarios
✔ Car engine/steel beam crushing (hammer weight ≥350kg)
✔ Handling of mineral materials such as iron ore and granite
✔ Cost-effective solution (15-30% lower procurement costs)
● Technology Upgrade
Duma Machinery's molybdenum-reinforced manganese steel Crusher Hammer By adding 1.2% molybdenum, the service life under high-temperature conditions is improved by 22%, making it particularly suitable for continuous crushing operations of hot-rolled steel plates.
2. Alloy Steel Hammer Head – The Epitome of Precision and Wear Resistance
● Differentiated Configuration
● High-carbon type (5.0–5.5% C): 58–62 HRC, specialized for electronic waste/thin-walled metals
● Low-carbon type (4.0–4.5% C): 50–55 HRC, suitable for crushing mixed materials
● Temperature Resistance Limit: Hardness retention exceeds 90% at 600℃
● Typical Applications
▷ 0-170kg Hammer Head: Fine Crushing of Laptops, Aluminum Profiles, and More
▷ 170-350kg Hammer Head: Handling Composite Materials like Home Appliances and Rebar
● Practical Validation
A certain electronic waste processing center uses Duma high-carbon alloy. Crusher Hammer Afterward, the monthly processing capacity increased to 920 tons, and the hammerhead replacement cycle was extended to 6,500 hours.
