5. Manufacturing Advantages & Quality Control

  • Strict Tolerance Control: Advanced 20-high cold-rolling and CNC slitting guarantee thickness tolerance of ±0.01mm or better (ISO 9445-b).
  • Superior Corrosion Resistance: Austenitic stainless grades (304L/316L) contain 18-22% Cr, up to 2.5% Mo, achieving exceptional anti-rust and acid/alkali stability.
  • Surface and Edge Finish: Up to BA (mirror), PVD, or No.4 finishes; edge can be round, deburred, or custom to enhance safety/processing.
  • Automated QC & NDT: 100% dimension/surface scan and non-destructive eddy current or ultrasonic testing; each roll assigned unique tracking code (meets FDA/EN ISO 9001, ISO 9445).
  • Long Service Life: High purity metallurgical structure ensures fatigue life exceeding 15 million cycles (per ASTM E466), and remains ductile after deep-drawing/bending.

9. FAQ – Professional FAQ on Precision Stainless Steel Strip

Q1: What are the main material grades for high quality precision stainless steel strip?
A: The most common are austenitic (304, 304L, 316, 316L), ferritic (430), and martensitic (420, 410), per ISO 15510 & ASTM A240. Each grade varies in corrosion resistance, mechanical strength, and suitability for forming.
Q2: What is the typical thickness & width tolerance of cold rolled stainless steel strip?
A: Cold rolled strip offers thickness tolerance down to ±0.01mm (ultra-precision ±0.003mm), width tolerance ±0.15mm, strictly per ISO 9445-1 and EN 10088-2.
Q3: How is surface finish (e.g., BA, 2B, PVD) selected for application?
A: Functional parts (springs, bands) generally require 2B or BA for anti-corrosion; PVD/mirror is specified for aesthetic/reflective or non-stick functions. Edge finish (slit, round) per installation safety or processing need.
Q4: What industry certifications or test standards are necessary?
A: Main certifications: ISO 9001 (QMS), ISO 9445 (dimensional tolerance), FDA (food/medicine), EN 10088, ASTM A480. Test methods: eddy current, ultrasonic, tensile as per EN ISO 6892-1, and non-destructive surface defect scan.
Q5: How is the strip delivered & what packaging is used?
A: Stainless steel strips are shipped as coils/rolls (10–1000kg per), protected with VCI paper & PE wrap, on fumigated wooden reels, with coil ID/OD as per client equipment, tested for seaworthy standards (per ASTM D4169).
Q6: What is the typical delivery time and guarantee?
A: Lead time: 7–15 days (standard sizes), 15–28 days (custom non-standard). All products carry minimum 12-month warranty with lifetime technical support. Each batch is traceable back to mill test certificate and chemical analysis.
Q7: Can I request custom mechanical properties or coil dimensions for automated lines?
A: Yes. Cold rolling and annealing can tailor yield strength, elongation, and hardness. Coil width, thickness, and ID/OD can be matched exactly to feeder or stamping system (typical tolerances: ±0.01mm thickness, ±0.15mm width).
