1. Core indicators for material selection ‌

‌304 stainless steel‌ (applicable to 90% of conventional scenarios)

Contains 18% chromium + 8% nickel, corrosion resistance meets the needs of daily environments (kitchens, homes, ordinary outdoor), service life can reach 20 years, cost-effective, price per meter is about 3-8 yuan (Φ1-5mm specifications) 311

‌316 stainless steel‌ (preferred for harsh environments)

Adding 2% molybdenum, the resistance to chloride ion corrosion is increased by 3 times, suitable for high-salt environments such as marine engineering and coastal buildings

Medical-grade 316L variants can be used for human implants, and biocompatibility is certified by ISO 109935

‌Special alloys‌ (professional fields)

904L stainless steel: contains copper, nickel, and molybdenum, resistant to sulfuric acid/phosphoric acid corrosion, used for chemical equipment filters12

β-titanium alloy: elastic modulus is close to 304 stainless steel, but the weight is reduced by 40%, suitable for lightweight aerospace needs

2. Scenario-based purchase suggestions ‌

‌Architectural field ‌

Preferred Φ4mm for curtain wall support 316 steel wire, wind pressure resistance level ≥4kPa13

Indoor decorative nets use Φ1.8mm 304 steel wire, with dense weave technology (mesh number ≥60) to enhance beauty

‌Home scene‌

Grape racks/hangers are recommended to use Φ2mm 304 soft wire, bending fatigue life ＞100,000 times13

Water pipe connectors need to match DN8-DN15 standard specifications, 316 material is recommended for rust prevention7

‌Industrial field‌

Chemical equipment filter nets need 904L material + Φ0.5mm dense weave, porosity control ≤5

Steel wire for food processing should comply with GB 4806.9-2025 standard, chromium migration <0.4mg/kg6

‌III. Pitfall avoidance guide‌

‌Low price trap identification‌

Beware of "three-no" products marked "stainless steel" but not marked 304/316, which may mix 202/302 materials (service life <5 years)4

Verify the nickel content in the quality inspection report (304 needs to be >8%, 316 needs to be >10%)

‌Certification verification‌

Construction steel wire must have GB/T 20878-2024 material certification

For food contact, check FDA or GB 4806.9 test report

‌V. Advanced purchasing tips‌

‌Surface treatment‌: Pickled surface corrosion resistance > bright surface > frosted surface

‌Supply chain optimization‌: Bulk purchase of steel wire above Φ5mm can require customized anti-relaxation reel packaging to reduce transportation deformation

By matching scene requirements and material characteristics, the performance value of stainless steel wire can be maximized. It is recommended to give priority to regular manufacturers that provide material traceability services 910.
