## 博客（中文）
- [The Furnace Chart That Saved a Production Line: Why Heat Treatment Paperwork Matters](/zh/blog/a286-bolt-heat-treatment-guide.md): When a heat-treat furnace drifted 18°C, 4,000 A-286 bolts were quietly under-aged. The customer's incoming hardness check caught it, but only because they checked.
- [Why High-Temperature Bolts Fail: 5 Failure Modes and How to Prevent Them](/zh/blog/bolt-failure-analysis-high-temperature.md): Analysis of 340 returned bolts from 12 customer sites reveals five failure modes account for 97% of high-temperature bolt failures. Forensic breakdown with prevention protocols for stress relaxation, creep rupture, hydrogen embrittlement, galling, and thermal fatigue.
- [How a Turbocharger Manufacturer Cut Bolt Costs 40% by Switching from Inconel 718 to A-286](/zh/blog/inconel-718-vs-a286-bolts.md): A Tier-1 turbocharger supplier was specifying Inconel 718 for all hot-side bolts, until our engineering team showed them they only needed it on 3 of 12 positions.
- [The Gas Turbine That Kept Shearing Stage-1 Bolts, Until We Changed One Word on the Spec](/zh/blog/nimonic-80a-vs-inconel-718-creep.md): A 120MW gas turbine was shearing Inconel 718 blade retention bolts every 8,000 hours. The fix wasn't a stronger bolt. It was a different alloy.
- [The $120,000 RFQ That Took Three Weeks to Quote, Because of One Missing Line](/zh/blog/superalloy-bolt-procurement-guide.md): A procurement lesson from a chemical plant expansion: how an incomplete fastener specification cost more in engineering time than the bolts themselves.
