***In regards to the Hastelloy-X and Hastelloy-C, we can offer dual wall and each item will vary.
Class of tolerance
The importance of industry standards is, that it ensures traceability and constant quality of products. The following industry standards are defined; IEC 60584-1 class 1, IEC 60584-1 class 2, IEC 60584-1 class 3, ASTM E230, ASTM E230 special limits and ‘class 1 on best effort basis’. Not all types of cable can be produced according to a certain type of class. Please contact us to get informed according to which norm, your specific cable is supplied.
Delivery time
Cables in stock can be shipped out the same day or the day that is determined as customer specific delivery date. For non standard stock items, production times may vary. Below you find a rough estimate of production times for non stock items. Please be informed that delivery time on order confirmation is leading.
| MI TC cable Express delivery |
20-22 weeks 11-13 weeks |
| MI cable with platinum wire | 5-8 weeks |
| MI cable with platinum sheath | 6-7 weeks |
