Frequently asked questions
Do I need an account to use SpecBase?
No. All alloy lookups, the composition validator, and the grade identifier are free and require no account or login.
What file formats does bulk CSV validation support?
Professional plan accepts CSV files with column headers matching element symbols (e.g. Ni,Cr,Fe,Mo) and a grade column. Up to 10,000 rows per upload.
How accurate are the composition ranges?
Ranges are sourced from published AMS, ASTM, and ASME standards. We update when standards are revised. Always cross-check against the official standard for production use.
Can I get a tamper-evident material certificate?
Yes — our certificate service issues immutable, timestamped certificates linked to your validated composition. Start a free pilot →
