Why source through Way Fast
We serve Tier 1 and Tier 2 automotive suppliers — primarily to North American OEM programs, including platforms shared with European and Japanese brands — with day-to-day experience handling the documentation and tolerance standards these projects demand.
01 · Multi-source capacityWorking with multiple qualified manufacturing partners — we match each order to the best-fit production line, stabilizing lead times and cost when single-source capacity tightens.02 · Submission-grade documentationFull support for PPAP (Levels 1–3), IMDS submission, and RoHS / REACH documentation.03 · Audited special-process chainPartners certified to AIAG CQI-9 (heat treat), CQI-11 (plating), and CQI-12 (coating) — covering the full post-processing chain under audited special-process controls.04 · Multilingual drawing reviewTechnical drawing review in English, German, Japanese, and Chinese — including ISO 8015 GPS callouts, JIS standards, thread tolerance classes, and coating specifications.05 · Grade selection and stock availabilityGrade selection matched to environment (marine / chlorinated / food contact / chemical / magnetic sensitivity) and strength requirement — drawing-reviewed against customer environmental spec. Baseline 304 / 316 / 410 in common head-and-length combinations supplied within standard lead time; non-standard grades (305, 420, 430, 630 / 17-4 PH) and custom combinations supplied per programme.Family coverage · 3 groupsSelecting across stainless-steel grade families
Austenitic (300 series)302 / 304 / 305 / 316 · non-magneticStandard corrosion-resistant grades, non-magnetic, good formability. 304 for general-purpose; 316 for marine, chlorinated, or chemical environments; 305 for cold-heading larger bolts where 304 would work-harden; 302 for high-strength fasteners.Ferritic & Martensitic (400 series)410 / 420 / 430 · higher strengthMagnetic stainless grades. 410 / 420 heat-treatable martensitic — higher tensile strength than 304 with moderate corrosion. 430 ferritic for cost-balanced applications where non-magnetic response is not required.Precipitation-hardening (SUS 630 / 17-4 PH)High strength + corrosion17-4 PH combines austenitic corrosion with martensitic strength after age-hardening. Tensile above 1,200 MPa achievable. For aerospace, marine, or aggressive environments where 300-series strength is insufficient.RangeSpecifications
