In industrial area with strong acid, high temperature and reducing media, traditional stainless steel quickly fails, while Hastelloy B3 pipe plays an important role through the molecular-level design of nickel-molybdenum alloy. HT PIPE is a Hastelloy Alloy B3 Pipe supplier with 15+ export experience. Contact us for more information and quotes for free!
Hastelloy N10675 pipe Chemical properities
The ultra-low impurity method is the genetic code of B3 alloy. The excessive compression of carbon and silicon content material (C≤0.02%, Si≤0.10%) makes the carbide precipitation in the heat-affected sector of welding nearly zero,and the corrosion resistance of the weld is on par with that of the parent material for the first time. The trace control of iron and chromium (Fe≤2%, Cr≤1%) is like a lock, firmly locking the risk of β phase precipitation in the medium-temperature brittle zone (650–870℃).
Alloy B3 pipe Corrosion Resistance
Alloy N10675 pipe Hydrochloric acid dominates the whole area
From room temperature dilute acid to 190℃ concentrated acid (≥20%), the corrosion rate curve is almost horizontal, breaking the curse of "hydrochloric acid has no metal".
Hast B3 defense of sulfuric acid
In medium concentration (40–60%) non-oxidizing sulfuric acid, molybdenum element forms MoO₂ passivation film, which remains inert even if chloride ions are mixed.
hastelloy alloy b3 organic acid
In 120℃ acetic acid and formic acid environment, the annual corrosion rate is <0.05mm, becoming the only choice for high-purity reactors for biopharmaceuticals.
hastelloy N10675 pipe Manufacture process
Rolling needs to be carried out in the 1000–1200℃. If the temperature falls into the 650–870℃ brittle zone for more than 8 minutes, the β phase will grow wildly along the grain boundary, and the toughness will drop by 17%. Modern factories use direct rolling water cooling technology to allow the plates to pass through the death temperature zone within 10 seconds.
