Product Description
ASME SA213 TP347Hadalah baja tahan karat austenit niobium-stabil yang dirancang untuk layanan suhu tinggi di superheater boiler ultra-superkritis (USC) dan reheater.Stabilisasi niobium mencegah precipitation kromium karbida selama pengelasan dan operasi suhu tinggi, memastikan ketahanan yang superior terhadap korosi intergranular dan sensitisasi.
- Niobium Stabilisasi:Menghilangkan risiko sensitisasi selama pengelasan, tidak memerlukan perawatan panas pasca pengelasan
- Kekuatan suhu tinggi:Kekuatan retak merangkak yang lebih baik dibandingkan dengan TP304H dan TP321H pada suhu di atas 600°C
- Resistensi oksidasi:Ketahanan yang sangat baik terhadap oksidasi uap dan korosi gas asap di lingkungan boiler USC
- Masa pakai yang panjang:Rekam jejak yang terbukti di pembangkit listrik superkritis dan ultra-superkritis di seluruh dunia
- Pelacakan penuh:Sertifikasi EN 10204 3.1 / 3.2 dengan laporan uji kimia dan mekanik lengkap
