Steels used for the connectors
The connectors offered by TECALEMIT FLEXIBLES are manufactured from carbon steel or stainless steels of type ANSI 316 Ti (DIN 1.4571 - AFNOR X6 Cr Ni Mo Ti 17 12 2) or ANSI 316L (DIN 1.4404 - AFNOR X2 Cr Ni Mo 17 12 2) meeting the most demanding quality requirements and coming from the best steel mills in Europe.
When the request is made at the time of the order, TECALEMIT is able to supply with the batches of connectors the following control documents, as per standard NF EN 10204 :
- Certificate Type 2.2: Control statement in which the manufacturer declares that the delivered products comply with the requirements of the order, and to which test results are added.
The tests control a product given specifications and manufacturing process.
NOTE: The controlled products are not necessarily the delivered products.
- Certificate Type 3.1: Inspection certificate 3.1 in which the manufacturer states that the delivered products comply with the requirements of the order and to which test results of the controlled sample of the delivered products are added.
Standard surface treatment:
TECALEMIT FLEXIBLES carbon steel connectors have a Chrome VI-free electrolytic galvanizing type surface treatment to comply with RoHS (2002/95 / EC), RoHS II (2011/65 / EU) and REACH (1907/2008 / EC).
The thickness of the applied surface treatment is between 8 and 12 μm in order to guarantee an average resistance of 400 hours to red rust (salt spray test according to ISO 9227 NSS, control criteria according to ISO 10289).
The connectors produced with this type of surface treatment are silver grey.
Reinforced surface treatments:
On request, a Zinc Nickel type surface treatment (electrolytic application of pure zinc alloy and 12-15% nickel) may also be offered.
This surface treatment provides excellent resistance to corrosion and oxidation (resistance to red rust between 750 and 1000 hours after tests according to ISO 9227 NSS, control criteria according to ISO 10289).
The connectors produced with this type of surface treatment are matte grey in color.
Other surface treatments are available on request.
