Jimmy Green Break Load Chart Advisory
These break loads are derived from published data and test certificates. The reporting method varies between manufacturers.
Essentially, the ultimate break load depends on the grade, and all manufacturers of the same grade of chain will have similar results.
|Weight per metre||0.8kg||1.1kg||1.45kg||2.3kg||3.25kg||3.9kg|
|Lofrans Grade 40||2447kg||4384kg||6893kg||9789kg|
|Titan Grade 43||4400kg||7200kg|
|MF Grade 40 in Kn||3059kg||4079kg||6424kg||9177kg||10809kg||12746kg|
|G3 A316L stainless steel in kg||3200kg||5000kg||7200kg|
|Cromox G6 Grade 60 in kg||3823kg||6424kg||10197kg||14531kg||17029kg|
|Cromox G6 PLUS Grade 60 in kg||3925kg||6730kg||10605kg||16315kg||18049kg|
|DAMS MF Grade 70 in Kn||7138kg||11217kg|
If you see a break load denoted in Kilonewtons (Kn), you can convert it as follows for comparison:
1 Kn = 101.972 Kg
For an accurate conversion, multiply the Kn value by 101.972 to calculate the break load in kg.
However, for a quick reference, add two zeros onto the Kn value for the approximate strength in kg, e.g. 43Kn becomes 4300kg.
Jimmy Green Marine offer a minimum Grade 40 hot dip galvanised calibrated anchor chain because size for size Grade 40 is approximately 25% stronger than Grade 30.
|Chain Size||Calibration||Grade 30||Grade 40|
Grade 43 (Titan) is slightly stronger than Grade 40
