ISUZU 6HK1 crankshaft(8-94396737-4) is made from high-quality raw materials 40Cr. Compared to cast iron crankshafts, they offer 27.9% higher tensile strength and 78.6% higher yield strength. The unique induction hardening process creates a 3-5 mm hardened layer (HRC 52-58), which improves wear resistance by 15% compared to nitrided cast iron. Our crankshafts have earned the trust of distributors worldwide.

Product Advantages

(1)Material Advantage: Forged Steel--40Cr
Data Comparison:Forged Steel vs. Cast Iron

Index	Our Forged Steel Crankshaft	Market Cast Iron Crankshaft	Customer Value
Tensile Strength	≥1000MPa	≤785MPa	Suitable for high-load conditions
Wear Life	3-5 years (heavy load)	1-2 years	Reduces maintenance costs
Low-Temp Toughness	AKV≥25J (-40℃)	AKV≤12J	Adapts to extreme climates (Russia, etc.)

(2)Medium Frequency Quenching (Heat Treatment)

The ISUZU 6HK1 crankshaft adopts medium frequency quenching and tempering processes to deliver consistent performance under harsh conditions. This advanced heat treatment ensures a uniform hardened layer depth of 3–5 mm and a surface hardness of HRC 52–58, effectively enhancing wear resistance and fatigue strength.

Unlike cast iron crankshafts that are prone to deformation and tolerance issues, our precision-forged crankshaft maintains excellent dimensional accuracy and structural integrity.

(3)Full-Process Quality Inspection
In the production process, there are more than 30 inspection procedures, including magnetic particle inspection, ultrasonic inspection, hardness inspection and dynamic balance inspection.
