Mechanical properties, corrosion behaviour and the full dimensional range for this grade.
A4 Stainless Steel Cylinder Connecting Sleeve are supplied to ISO 3506 group A4 (316 / 1.4401), commonly supplied A4-80. Corrosion behaviour is superior, including marine and chloride environments, the material is largely non-magnetic, and the usable service range is approx. -200 °C to +400 °C, subject to the property class and the joint. In practice this grade is specified for marine, coastal and chemical applications.
Property values are typical for the grade. Certified mechanical test data is available on request for production orders.
A4 Stainless Steel is not a material cylinder connecting sleeve are supplied in. Cylinder Connecting Sleeve are specified by nominal size, and this combination does not describe a part that exists.

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
A4 Stainless Steel Cylinder Connecting Sleeve — GB/T 5783 / ISO 4017 (Series 013) are largely non-magnetic.
A4 Stainless Steel Cylinder Connecting Sleeve — GB/T 5783 / ISO 4017 (Series 013) provide superior, including marine and chloride environments with a service range of approx. -200 °C to +400 °C, subject to the property class and the joint.
For Cylinder Connecting Sleeve — GB/T 5783 / ISO 4017 (Series 013), A4 Stainless Steel suits general indoor and outdoor use; A2 (304) is preferred for marine, coastal and chemical environments. Choose by corrosion exposure first.
Yes — stainless on stainless is prone to thread galling under load, especially at smaller sizes. Use an anti-galling lubricant or wax thread compound, and slow the tightening rate where possible.
