Industrial furnaces, heat‑treatment kilns and thermal processing equipment operate under extreme high‑temperature conditions. Components inside these facilities face constant oxidation, thermal cycling, thermal shock and creep stress. Using improper cast materials will lead to scaling, cracking, deformation and frequent part replacement, which brings high maintenance cost and unexpected production downtime. For many high‑temperature operating scenarios, **1.4823 (GX40CrNiSi27‑4)** heat‑resistant steel castings have become one of the most reliable material choices.
Products Description
What is 1.4823 (GX40CrNiSi27‑4) ?
1.4823 is a widely‑recognized DIN standard heat‑resistant cast alloy. Its full DIN designation is G‑X40CrNiSi27‑4. This is a chromium‑nickel‑silicon rich cast steel, designed specifically for continuous high‑temperature service.
Compared with ordinary stainless castings, extra silicon content greatly improves its high‑temperature anti‑oxidation capacity. The balanced Cr‑Ni ratio ensures stable microstructure when heated and cooled repeatedly. This alloy does not rely on surface coating; its inherent material property provides long‑lasting protection under furnace atmosphere.
Core Performance Advantages of 1.4823 Castings
1. Outstanding high‑temperature oxidation resistance
The alloy forms a dense protective oxide layer on component surface under high heat, effectively slowing scaling and metal burning loss. It performs well in air‑rich furnace environment.
2. Good thermal shock and thermal cycling resistance
Frequent heating‑cooling cycles are common in batch‑type furnaces. 1.4823 castings can withstand repeated temperature fluctuation, lowering the risk of thermal cracking.
3. Satisfactory creep strength at elevated temperature
Under long‑term high‑temperature load, parts made of 1.4823 keep good dimensional stability, resisting creep deformation. It extends component service life and reduces shutdown for replacement.
4. Good casting process adaptability
This grade is suitable for manufacturing complex‑shape furnace spare parts. We can produce parts according to customer drawings or physical samples, covering light‑weight small fittings and heavy‑duty large furnace components.
Main Application Fields of 1.4823 Heat‑Resistant Castings
1.4823 castings are extensively supplied for thermal‑processing industries:
‑ Industrial furnace components: furnace grates, support beams, furnace bases, fixture trays
‑ Heat‑treatment fixtures, baskets, retorts and carrier parts
