Designed to increase security and reduce risk, the new precision Sandvik 21-6-9 Aerospace seamless tubing is an austenitic stainless steel grade with high mechanical strength and good impact toughness in temperatures down to -230°C (-382°F) with full traceability from the melt to final product.
“Material reliability in aircraft applications is always a first consideration,” explained Christofer Hedvall, Sandvik’s technology and innovation manager. “By eliminating the use of welded seams in the tubing, considered to be a weak link and hence a risk, you eliminate any concerns there may be over potential failure in operation.
“By launching this new seamless tube product at Airtec 2016 we certainly anticipate generating considerable interest,” he continued. “We look forward to talking with visitors to Airtec about the increased security and new opportunities offered by our seamless tubing and establishing new business partnerships.”
The seamless stainless steel Sandvik 21-6-9 tubes are supplied in the bright annealed condition or cold worked in a range of sizes from 2 - 65mm and wall thicknesses of 0.3 - 25mm. All are produced to the standard AMS 5561 standard.
Examples of the material will be on display at Airtec and a presentation will be delivered by Christofer Hedvall on Wednesday, October 26th at the Fair, titled ‘Increased security, development, advantages and impact of the first seamless tube in 21-6-9 for aerospace applications’.
