  8.經(jīng)美國(guó)腐蝕工程師協(xié)會(huì)NACE標(biāo)準(zhǔn)認(rèn)證（MR-01-75)符合酸性氣體環(huán)境使用的最高標(biāo)準(zhǔn)等級(jí)Ⅵ。

  金相結(jié)構(gòu)：625為面心立方晶格結(jié)構(gòu)。當(dāng)在約650℃保溫足夠長(zhǎng)時(shí)間后，將析出碳顆粒和不穩(wěn)定的四元相并將轉(zhuǎn)化為穩(wěn)定的Ni3（Nb，Ti）斜方晶格相。

  固溶強(qiáng)化后鎳鉻矩陣中的鉬、鈮成分將提高材料的機(jī)械性能，但塑性有所降低。

  1.On the oxidation and reduction of various environmental corrosive media have a very good corrosion resistance.

  2.Excellent resistance to pitting and crevice corrosion ,and does not produce chloride-induced stress corrosion cracking.

  3.Excellent resistance to inorganic acid corrosion ,such as nitric acid phosphoric acid ,sulfuric acid ,hydrochloric acid and sulfuric acid and hydrochloric acid mixed acid.

  4.Excellent resistance to all kinds of inorganic acid mixed solution corrosion ability.

  5.When the temperature reaches 40℃ ,it can show good corrosion resistance in various concentrations of hydrochloric acid solution.

  6.Good process ability and weld ability ,and no post weld cracking sensitivity.

  7.Have a wall temperature of -196-450C in the manufacture of pressure vessel certification.

  8.Certified by the American Society of Corrosion Engineers NACE Standard ( MR-01-75),meets the highest standards for acid gas atmospheres Class.

  Metallographic structure :Face-centered cubic lattice structure .When the insulation in about 650C long enough ,the precipitation of carbon particles and unstable quaternary phase and will be converted to stable Ni3 ( Nb,Ti )orthorhombic phase.

  The molybdenum and niobium components in the Ni-Cr matrix after solid solution strengthening will improve the mechanical properties of the material ,but the plasticity will be reduced.
