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.
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.
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 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.
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 |
