Core Alloy Feature: Niobium (Cb/Columbium) added stabilization design, locks free carbon inside matrix to avoid chromium carbide precipitation;Superior anti-intergranular-sensitization performance in continuous 425°C~815°C sensitizing temperature zone (performa anti-intergranular-sensitization yang lebih baik dalam zona suhu 425°C~815°C)

Differentiated Core Point: Distinct from titanium-stabilized 321, molybdenum anti-corrosion 316/317 family and low-carbon grade 316L/317L, 347 adopts niobium alloying,excels at long-period high-temperature creep resistance and high-pressure thermal circulation condition (menonjol pada kondisi sirkulasi termal bertekanan tinggi dan tekanan tinggi); bundled one-stop bending processing saves customers independent outsourcing cost

Application Direction: High-pressure boiler accessories, thermal power pipeline fittings, petrochemical high-temperature pressure vessel components, air mancur, air mancur, air mancur, air mancur, air mancur,heat exchanger formed parts and high-temperature mechanical structural bending parts (bagian dan komponen pembentuk penukar panas dan suhu tinggi)

347 cold rolled stainless steel belongs to specialized stabilized heat-resistant stainless steel formulated per strict ASTM industrial norms, atau yang lebih dikenal sebagai stainless steel stainless steel.Diposisikan sebagai bahan tahan creep suhu tinggi yang ditingkatkan melampaui baja stabil 321 konvensional dan semua stainless grades anti korosi yang mengandung molibdenum.While 321 uses titanium for carbon fixation focusing on regular medium-high temperature alternating environment, 347 replaces titanium with columbium as stabilizing element. While 321 uses titanium for carbon fixation focusing on regular medium-high temperature alternating environment, 347 replaces titanium with columbium as stabilizing element.Niobium memiliki kapasitas kombinasi yang lebih kuat dengan karbon bebas., membentuk niobium carbide stabil untuk benar-benar menekan gran boundary carbide precipitation,Jadi material ini mempertahankan struktur metallographic yang utuh di bawah beban suhu tinggi dan lingkungan creep termal jangka panjang., sebuah properti inti baja tahan karat rendah karbon biasa tidak dapat direalisasikan melalui kontrol komposisi karbon rendah tunggal.Produk kami mengintegrasikan penjualan lembaran mentah dan mendukung layanan pembentuk bending CNC ke dalam satu paket., berbeda dari sebagian besar pemasok baja hanya memasok pelat baja datar tanpa post-processing; klien menerima ready-to-install bent finished parts directly after order,Cutting intermediate transport and multi-supplier coordination trouble (Mengurangi transportasi menengah dan masalah koordinasi multi-supplier)Semua bahan baku sepenuhnya sesuai dengan komposisi kimia ASTM dan indeks sifat mekanik.each batch accompanied with official inspection document for overseas customs clearance and industrial project acceptance setiap batch disertai dengan dokumen inspeksi resmi untuk clearance bea cukai luar negeri dan penerimaan proyek industri.

The biggest competitive edge of ASTM standard 347 stainless steel lies in outstanding high-temperature creep resistance and permanent anti-sensitization brought by niobium stabilization mechanism.

The biggest competitive edge of ASTM standard 347 stainless steel lies in outstanding high-temperature creep resistance and permanent anti-sensitization brought by niobium stabilization mechanism. The biggest competitive edge of ASTM standard 347 stainless steel lies in outstanding high-temperature creep resistance and permanent anti-sensitization brought by niobium stabilization mechanism.When equipment runs under long-term constant high temperature plus continuous pressure load (Ketika peralatan berjalan di bawah suhu tinggi yang konstan dan beban tekanan yang konstan), baja tahan karat umum secara bertahap menghasilkan embrittlement batas butir dan struktur creep deformasi, yang akhirnya memicu deformasi komponen dan kebocoran peralatan.Thanks to fixed niobium element locking free carbon (Terima kasih untuk niobium yang tetap mengunci karbon bebas), 347 tidak akan menghasilkan korosi intergranular no matter long-term dwell in sensitization temperature range or repeated high-temperature welding assembly;Weld zone performance keeps consistent with base metal without post-weld solid solution heat treatment Performa zona las tetap konsisten dengan base metal tanpa post-weld solid solution heat treatmentDibandingkan dengan 321 titanium-stabilized plate,347 gains obvious superiority under high-pressure high-temperature creep working condition, especially suitable for thermal power, chemical high-pressure pipeline components with long service cycle requirement.

The refined cold rolled grain structure effectively improves material bending ductility, avoids cracking.kerutan dan permukaan peeling during sharp-angle bending and complex arc forming, yang sangat penting untuk jaminan kualitas layanan bending kami.

In daily atmospheric and mild industrial waste gas environment, 347 retains standard austenitic stainless steel's inherent rust-proof capacity, yang dapat menghalangi karat dari permukaan.Resisting normal air oxidation and weak corrosive flue gas erosionTanpa tambahan molibdenum tinggi seperti seri 317, itu tidak dirancang untuk konsentrasi tinggi klorida dan penyerapan asam yang kuat.thus cost is more competitive for pure high-temperature thermal equipment projects than heavy anti-corrosion alloy steel. Dengan demikian biaya lebih kompetitif untuk proyek peralatan termal suhu tinggi murni daripada baja paduan anti-karat berat..
