Bolt property classes, high-strength carbon steel grades and stainless alloys for wind turbine fastener applications — how to select the right material for each load, environment and standard.
10.9 vs 12.9 bolt grades for wind turbine towers — mechanical properties, hydrogen embrittlement risk, coating compatibility, and which grade most OEMs specify.
304 vs 316 stainless steel for wind turbine and offshore fasteners — corrosion resistance, pitting potential, A2 vs A4 property classes, and when duplex stainless is needed.
Duplex vs super duplex stainless steel fasteners for marine wind turbine applications: PREN thresholds, grades 1.4462 and 1.4410, cost trade-offs, and application zones.
How to read the bolt property class system in ISO 898-1 — what 8.8, 10.9 and 12.9 mean for tensile and yield strength, proof load, and which classes wind turbines use.
