3 Steel Champions for Industrial Success
#1 40Cr Alloy Steel – Umphakathi Wokonga
✔️ Best for: Iprojekthi ezisebenza ngentengo & izingxenye ezilula
✔️ Izinzuzo Eziyinhloko:
- 15-20% lower material cost vs premium steels
- Easy machining with standard CNC tools
- Achieves HRC 45-50 after quenching & tempering
Typical Uses: 典型用途:
⚙️ Izi zikhala ⚙️ Izi zikhala zePrototype ⚙️ Izigaba zemishini yezolimo
#2 20CrMnTi Case-Hardening Steel – Umphakathi Wokugcina
✔️ Imfihlo Isikhali: Ukucindezela kudala ubuso obufana nedayimane (HRC 58)
✔️ Ise Best Ngaphansi:
- High cyclic stress (15+ impacts/min)
- Iziqhamo ezinzima ezihlanjululwe ngophethiloli
- Mining/construction equipment
Pro Tip:
Deep carburizing (1.2-1.5mm) boosts service life by 40% in crusher rotors
#3 4Cr13 Martensitic Stainless – I-Corrosion Crusher
✔️ Unbeatable In:
- Coastal/chemical environments (10x rust resistance vs carbon steel)
- Medical/food-grade applications (ISO 13485 compliant)
- Precision components (±0.005mm stability post cryo-treatment)
Smart Selection Flowchart
- Priority Check:
Budget > Performance? → 40Cr
Harsh Environment? → 4Cr13
Heavy Loads? → 20CrMnTi
- Lifecycle Cost Calculator:
👉 4Cr13 saves $2.8k/ton in maintenance over 5 years in humid climates
虽然4Cr13具有最佳性能，但我们仍需根据加工条件和成本预算全面考虑。
