Description
Hangzhou Ever-Power Sprocket Co., Ltd.
ANSI 100 stainless steel sprockets — extra-heavy pitch for the highest torque industrial drives in corrosive environments.
Product Overview
When industrial drive requirements scale beyond what #80 chain can efficiently handle, the #100 Stainless Steel Sprocket steps in with a 31.75 mm (1-1/4 inch) pitch that accommodates the ANSI 100 roller chain family. At this pitch, individual chain links — and therefore individual tooth loads — are substantially larger, and the corresponding sprocket diameters are impressively robust pieces of precision machinery. Hangzhou Ever-Power produces these sprockets from heavy-section 304 or 316 stainless steel billet that first undergoes ultrasonic inspection to confirm freedom from internal voids before a single machining pass is taken. The resulting sprockets serve in the most demanding environments across heavy industry — steel mill scale-breaker chains, large-format printing press drives, continuous casting machine chains, and heavy offshore equipment — where no compromise between load capacity and environmental resistance is acceptable.

Material Quality at the #100 Scale
At the #100 pitch, each sprocket contains a significant volume of material — and any internal void or segregation zone that might be acceptable in a smaller part becomes a potential fatigue crack initiation site in a large, heavily loaded sprocket. Our procurement standard for #100 SS billet requires mill-certified chemical composition, mechanical properties, and positive-material identification (PMI) before stock acceptance. Ultrasonic testing is applied to all billet over 120 mm diameter to screen for laminations or pipe defects. Only clean-tested material progresses to the machine shop floor, giving our customers confidence that the inspection report attached to their order reflects the actual material inside each sprocket — not just the mill certificate for the heat.
Heat Treatment Options
Solution annealing (1,050–1,100 °C water quench) restores maximum corrosion resistance after machining by homogenising the stainless microstructure and eliminating sensitized zones near weld-heat-affected zones or after heavy cold work. For applications requiring higher surface hardness without sacrificing corrosion resistance, our selective induction hardening process raises tooth-face hardness to HRC 42–48 while the hub and disc remain in the softer, tougher annealed condition.
Where #100 Stainless Sprockets Are Deployed

Customer Testimonials
“Ever-Power manufactured 24 custom #100 SS sprockets for our acid pickling line at 32T and 48T. All arrived with UT clearance certs and CMM reports. Dimensional accuracy was excellent — we verified every bore in-house.”
“Used for a mooring chain tensioner on an offshore platform. Eighteen months in a seawater spray environment and the sprockets look brand new. Worth every penny of the 316 SS upgrade.”
“Complex custom order with step-hub profile. Communications were clear throughout, drawings reviewed twice before machining. Delivered in 22 days — reasonable for bespoke large stainless work.”
