Engineer-to-engineer selection guides, validated data tables, and practical tools for specifying high-temperature superalloy fasteners.
These technical resources are drawn from our in-house metallurgy lab, VIM+VAR melting data, and two decades of fastener manufacturing experience. Each guide is maintained by our engineering team and updated as new heat data becomes available. For questions not covered here, our metallurgists respond within one business day.
Temperature, environment, load, standard, worked into a grade recommendation in four steps.
Tightening torque for M6 to M100, by grade, thread class, lubrication condition and temperature.
Tensile and yield retention from 20 degC to 815 degC across all six grades.
PREN, crevice thresholds, SCC susceptibility and galvanic pairings, grade by grade.
ASTM, AMS, DIN, EN, GB and JIS cross-reference, plus the EN 10204 certificate grades.
The thirty questions engineers ask before specifying a high-temperature fastener.
