Description
Hangzhou Ever-Power Sprocket Co., Ltd.
Most industrial buyers do not need a UT-tested, PMI-verified, solution-annealed stainless sprocket. If you do — this is the page you were looking for.
Who Actually Needs an #100 SS Sprocket at This Specification Level
The #100 pitch stainless steel sprocket is not a product for general industrial use. The load this chain size carries — with individual tooth forces that can exceed 20 kN in heavy-duty applications — means that material integrity is a structural question, not just a quality preference. The buyers who contact us for this product are: steel mill engineers specifying scale-breaker conveyor drives in HCl pickling lines; offshore platform OEMs building mooring tensioner chains; continuous casting machine builders who need strand-guide sprockets to operate in steam and scale; and heavy chemical plant engineering teams whose drive runs through a reactor vessel environment where a sprocket failure means an emergency shutdown that costs more in one hour than a year’s supply of sprockets. If you are in one of those groups, the Ever-Power #100 Stainless Steel Sprocket is specified exactly for your requirement. If you are not — consider our #60 or #80 range, which meets the needs of the majority of heavy industrial applications at a lower price point.
The Specification That Sets This Apart
Standard stainless sprockets are produced from certified bar stock and inspected after machining. Our #100 SS sprocket production goes further at every step, because at this scale, “standard” is not sufficient for the environments these parts operate in:
Every billet over 120 mm diameter is UT-scanned before the first cut. Internal voids, laminations, and pipe defects that would never show on surface examination are caught and rejected at the material stage.
Each billet is XRF-scanned individually — not sampled by lot — to confirm grade composition. Grade substitution (304 passed off as 316) is a real-world risk that per-item PMI eliminates absolutely.
Post-machining solution anneal at 1,050–1,100 °C + water quench dissolves chromium carbides and restores maximum corrosion resistance through the full cross-section.
UT clearance report, PMI record, MTR (EN 10204 3.1), CMM dimensional report, and production traveller — all cross-referenced by heat number and order serial number.
Technical Specifications
| Parameter | Value |
|---|---|
| Chain No. | ANSI 100 |
| Pitch | 31.75 mm (1-1/4″) |
| Material | 304 SS / 316 SS (PMI-verified per item) |
| Billet QC | UT per ASTM A388 + PMI per item |
| Tooth Range | 8T – 48T (larger on request) |
| Compliance | ANSI B29.1 Class A, ASTM A388, ISO 9001:2015 |
The Environments Where This Sprocket Is Specified
| Buyer Type | Why #100 SS with Full Spec |
|---|---|
| Steel Mill Engineer | HCl pickling line: high load + aggressive acid. A void in the tooth root means unannounced fracture in an acid mist environment. |
| Offshore Platform OEM | Seawater + shock load + safety-critical overhead lifting. Material integrity is a safety requirement, not a preference. |
| Continuous Casting OEM | Thermal cycling, scale, steam. Sensitized stainless fails in this environment — solution annealing is not optional. |
| Heavy Chemical Plant | Reactor charging conveyor: acid/alkali, high load, inspection interval 12+ months. Zero-defect material is the only acceptable specification. |

What Engineers Say After Their First Order
“Our TÜV auditor reviewed the UT clearance, PMI record, and MTR together. He said it was the most complete material documentation package he had seen from an Asian sprocket supplier. That made the procurement approval straightforward.”
“Offshore platform mooring tensioner — 18 months of direct seawater spray on 316 SS #100 sprockets. They look brand new. We had budgeted for a replacement at 12 months. We did not need it.”
“Complex step-hub drawing — reviewed twice before machining, which is the correct approach. Delivered on time. The documentation set satisfied our engineering director without further queries.”
