MF DAMS Grade 70

High Strength Grade 70 Hot Dip Galvanised Calibrated Anchor Chain from MF Catenificio in Italy

Designed for the extra stresses and strains associated with extended cruising and for saving weight on a long anchor rode by taking the opportunity to step down one size in the chain.

Grade 70 chain is manufactured to such a high specification that it is possible to substitute e.g. 10mm Grade 40 anchor chain with a far longer length of 8mm Grade 70 without losing any strength.

MF Catenificio Frigerio Hallmark Stamping Assurance

Each batch of chain is subjected to a series of strict load traction, breaking and bending resistance examinationss which test the physical and mechanical characteristics under conditions of maximum stress, ensuring that every weld is 100% guaranteed.

Jimmy Green MF DAMS Grade 70 Calibrated Anchor Chain is sourced exclusively and directly from MF Catenificio Frigerio, a modern chain manufacturing plant in Italy.

MF Catenificio manufacturing is all carried out in their own research, test and ISO9001 attested production facility. The whole state of the art enterprise is located in Olginate, near Lecco, Lake Como, Italy.

The Concept and Development of MF High Strength Calibrated Anchor Chain

The original concept, design and production of increased strength Galvanised Anchor Chain is the brainchild of Corrado Maggi, lately of Maggi Catene, erstwhile top quality Italian chain manufacturers. Corrado has been instrumental in the development of DAMS Grade 70 for MF Catenificio. Corrado originally designed and developed a specially-engineered combined chemical and heat treatment to improve the tensile resistance of Grade 40 chain to high strength hot dip galvanised Grade 70 Anchor Chain. Note that the special part of this process is that the subsequent galvanising treatment which involves dipping the chain into molten zinc does not adversely affect the newly enhanced strength. Different manufacturers have tried to copy Corrado's formula, but it remains a trade secret which is now closely guarded by the design technicians at MF Catenificio.

MF Catenificio market their High Strength Grade 70 Chain as DAMS which stands for Downsizing Anchoring and Mooring System

MF DAMS High Strength Grade 70 Calibrated Anchor Chain Plus Factors - this is the Jimmy Green interpretation of the translations expressed in the MF catalogue:

• Weight Reduction
• Volume Reduction
• Optimises the redistribution of weight onboard
• Maximises possible chain length
• Facilitates deep water anchoring
• Optimises chain locker stowage 
• Requires less retrieval power
• Smoothes the passage of the chain, both up and down

MF DAMS Grade 70 Calibrated Anchor Chain features EN ISO 461 Regulated Hot Dip Galvanising to a micron depth of  80 ± 10 µ. delivering excellent protection against corrosion.

• Hot-dip galvanising anchor chain is a challenging process which involves immersing the chain in a molten zinc bath.
• The molten zinc chemically reacts with the surface of the steel to create an iron-zinc alloy.
• The result is a deep protective treatment to a minimum depth of 80 microns regulated to the EN ISO 461 standard.
• MF Galvanising provides longlasting resistance to abrasion and corrosion.
• MF Catenificio hot dip galvanising performance is further guaranteed by stringent application of their state of the art Salt-Spray testing treatment. 

MF Catenificio Salt Spray Galvanisation Test

The MF Salt Spray Test, developed by the MF Laboratiory Team and introduced in 2023 scrutinises the effectiveness and durability of the galvanising treatment.

The MF testing laboratory conducts a stringent examination of each batch of chain, exposing it to a concentrated salt solution for 24/48 hour cycles.

Salt Spray Testing simulates the real environmental conditions to which the chain will be exposed during its service life.

The results are governed by the MF Catenificio Frigerio UNI EN ISO 9001 certified quality system.

The entire MF chain manufacturing process has Lloyds Register approval to the ultimate ISO 9001 quality standard:

MF LLOYDS REGISTER APPROVAL TO ISO 9001

Jimmy Green Anchor Chain Quality Control and Accountability

Every length of chain is checked and labelled with the manufacturer, the date received, and a corresponding batch number when it arrives.
The batch number is then recorded at the point of sale.
Every chain order is, therefore, traceable and accountable to the Manufacturer Test Certificate.
