forged stainless steel and aluminum
Airsports, LLC and its European partner CWH sa. manufacture the highest quality skydive harness hardware in forged stainless steel. Our unique products have all been designed and tested by leaders in the fields of rigid and soft canopy flight. Each manufactured batch is tested and certified by an independent laboratory and their certificates accompany each sale.
Our quick links are supplied to us by KONG/Bonaiti in Monte Marenzo, Italy, Each is certified to the European norm EN 12275/Q – EN362/Q.
What We Offer
Rings
Our 316L stainless steel rings are shaped by cold forging on a 1000 ton press. This pressure deformation strain hardens and densifies the material and significantly increases its strength.
Adjusters
Products include SR888, CWH SL, AS 22040, MS 22040 and more..
D-Rings
The rings are trimmed and tumble polished to remove burrs and then vibratory polished to a high luster. Each manufactured batch is tested and certified in an independent laboratory for dimensional consistency.
Quick Links
Our stainless steel quick links are supplied by Kong/Bonaiti and are certified to CE EN 362/Q. We also stock selected Maillon Rapide quick links.
Snap Shackles
Featuring the KONG Frog – With an innovative approach that characterizes KONG comes the Frog, a revolutionary directional connector with an automatic clamping action that engages when it touches the anchor point.
Carabiners / Snap Hooks
Kong in Italy is a pioneer in the design and manufacture of carabiners and snap hooks of all types for climbing, paragliding, hang gliding, safety, and rescue work.
Bronze Snap Shackles / Brummel Hooks
308 Ring and swivel with rapid slide-in connection. Particularly suited for rapid coupling of lags for signaling.
Miscellaneous
The patented Skyhook System was developed by United Parachute Technologies of DeLand, Florida. Airsports LLC provides the metal parts to the system under contract.
Cold Working
Specially Designed Presses
Cold working or cold forging is accomplished on specially designed presses using hard steel dies that shape metal material slowly under thousands of tons of force at or near room temperature.
Alloy Grain Structure
Cold working compresses alloy grain structure to a fine, dense condition that improves its tensile and yield strength but without the distortion or scaling effects found in hot forging. Cold worked parts generally require less post forge polishing to achieve a smooth surface. It is an ideal process for manufacturing small parts such as parachute and climbing hardware.
Martensitic Stainless Steel
Martensitic stainless steel alloys of the 400 series require heat treatment to improve hardness. Austenitic alloys such as 316L are less costly and are hardened only by cold working. The cold work process densifies the material by crowding together its grains to a finer structure for better fatigue resistance.
Benefits
Cold working can increase material temper to quarter hard, half hard, full hard, spring or extra spring with improved finish properties and higher corrosion resistance over Martensetic alloys.
Compare these alloys:
| Hot Forged 316L | = | 84,100 lbs/in2 |
| Hot Forged 17.4ph | = | 190,000/in2 |
| 316 Cold Forged | = | 180,000/in2 |
