Precision Stainless Steel Strip
Precision stainless steel strip (also called precision stainless steel coil) is cold-rolled stainless and special-alloy strip processed to tight thickness, width, flatness, and hardness tolerances for applications where dimensional consistency and surface quality are critical - including electronics, new energy, aerospace, medical devices, welding consumables, and precision springs.
Shanghai Xudeng Industrial has built a strong reputation over 15 years as a reliable processor and supplier of stainless steel. Through consistent growth, we now operate from an integrated 20,000+ sqm facility dedicated to precision processing, surface finishing, and supply chain management. Our focus remains on delivering high-quality stainless steel products and solutions to our customers worldwide.

Key Properties |
Primary Application |
| 304 |
S30400 |
1.4301 |
Standard universal austenitic grade. Excellent all-round corrosion resistance and formability in a wide range of environments. |
General-purpose applications: Kitchen equipment, food processing machinery, architectural trim, industrial tanks, and general hardware. |
| 304L |
S30403 |
1.4307 |
Low-carbon version of 304. The reduced carbon content minimizes harmful carbide precipitation during welding, preserving corrosion resistance in as-welded condition. |
Applications requiring extensive welding: Chemical containers, welded structures, and components where post-weld heat treatment is not feasible. |
| 316 |
S31600 |
1.4401 |
Molybdenum-bearing austenitic grade. The addition of 2-3% Mo provides superior resistance to pitting and crevice corrosion in chloride-containing environments. |
Marine and chemical processing: Boat fittings, coastal architectural components, chemical processing equipment, and pharmaceutical apparatus. |
| 316L |
S31603 |
1.4404 |
Low-carbon version of 316. Combines the enhanced chloride resistance of 316 with excellent resistance to weld decay, ideal for welded assemblies in corrosive settings. |
Welded assemblies in corrosive environments: Pressure vessels, piping, and structural parts for marine, chemical, and high-purity industries. |
| 301 |
S30100 |
1.4310 |
High work-hardening rate. Can achieve remarkably high strength and hardness through cold working processes like rolling or drawing. |
High-strength structural components: Railway car bodies, automotive trim and frames, springs, and conveyor belts. |
| 321 |
S32100 |
1.4541 |
Titanium-stabilized austenitic grade. The addition of titanium prevents chromium carbide formation during exposure to the 450-850°C range, preserving corrosion resistance after welding or high-temperature service. |
High-temperature welded assemblies: Aircraft exhaust systems, heat exchangers, expansion bellows, and furnace parts. |
| Other grades (e.g., 347, 317L,) are available upon inquiry. |
