Bag hardware of the abrasion resistance-B

Bag hardware correlation between operating environment and wear resistance

High friction scenarios (e.g. industrial machinery)

Recommended 316 stainless steel + PVD coating, Taber wear test (CS-10 wheel, 500g load) up to 5000 rpm without bottoming out.

Low frequency contact scenarios (e.g. consumer goods)

Aluminium anodising + hard oxidation (thickness ≥25μm) can meet the requirements, reducing costs by more than 30%.

Extreme environments (e.g. offshore platforms)

Need to use super duplex stainless steel (such as S32760) + electrochemical polishing, Pitting Resistance Equivalent (PREN) ≥ 40, corrosion rate <0.01mm/year.

Wear resistance test standard reference

Bag hardware ASTM D4060 (Taber Wear Test)

Used to assess the wear resistance of organic coatings, metal hardware can refer to its test principle, by adjusting the load and number of revolutions to simulate the actual wear.

ISO 15184 (Pencil Hardness Test)

Used to assess the hardness of coatings, the surface hardness of bag hardware with good abrasion resistance should be ≥ 6H.

Bag hardware recommended programme

High wear resistance requirement

316 stainless steel substrate + PVD TiN coating (thickness ≥ 3μm), Taber wear test ≥ 8000 rpm.

Cost-effective solution

6061 aluminium alloy + hard anodised (thickness ≥25μm), cost reduction of 40%, wear resistance to meet daily use.

Decorative demand

H62 brass + chemical nickel plating (thickness ≥ 5μm), both wear-resistant and beautiful, suitable for indoor low-frequency contact scenarios.

Through the reasonable choice of material, technology and structural design, the wear resistance of bag hardware can be significantly improved and the service life can be extended.

Bag hardware summary

High-end bags: give priority to pure steel or high-strength aluminum alloy hardware, combined with anodic oxidation or multi-layer plating process to ensure wear resistance and service life.

Mid-range bags: zinc alloy is the cost-effective choice, but need to improve wear resistance through surface treatment.

Daily use: avoid prolonged exposure of hardware to harsh environments, and regular maintenance can prolong the service life.
