- Product Introduction
Heat resistant circular cast steel tray is a ring-shaped load-bearing container formed through casting process, designed for high-temperature working conditions, used for safe transportation, temporary storage or processing of high-temperature materials (such as metal ingots, slag, heat-treated workpieces, etc.). Its core value lies in high temperature strength and antioxidant performance.
Its core features:
High temperature stability:
Working temperature range: 550 ° C to 1150 ° C (depending on material grade).
Resist thermal deformation, creep, and oxidation peeling.
Structural reliability:
Cast steel integrated molding, no weld weak zone, resistant to mechanical impact.
Circular design disperses stress and avoids local overheating failure.
Environmental adaptability:
Resistant to complex industrial conditions such as oxidizing/reducing atmospheres and sulfur-containing environments.
Our advantages
Material and formula advantages
The high chromium silicon formula (Cr 26-28%+Si 2-3%) generates a Cr ₂ O ∝ - SiO ₂ composite oxide layer, which is extremely resistant to oxidation/sulfur corrosion at 1100 ℃. The nickel content is low (≤ 1.5%), and the cost is reduced by 40% compared to nickel based alloys.
Manufacturing process advantages
Electroslag remelting (ESR) purification (S/P ≤ 0.025%), directional solidification to eliminate shrinkage porosity, patented step heat treatment to optimize grain boundary carbides, improve toughness by 30%, and suppress σ phase embrittlement.
Performance advantages
1100 ℃ oxidation rate ≤ 0.2 mg/cm ² · h (4 times better than HK30 alloy)
Sulfur corrosion resistance limit: H ₂ S 1000 ppm
800 thermal cycles (Δ T=850 ℃) ↔ Water quenching does not fail, and the anti peeling performance is improved by 50%
Standard advantages
French NF standard core certification, providing EN 10204 3.1B certificate and ASTM G54 oxidation report for each batch, in compliance with the EU PED directive and RoHS 2.0 environmental protection, with zero global compliance risk.
