Scope
GB/T 21433-2008 is the English-translated version of 不锈钢压力容器晶间腐蚀敏感性检验.
GB/T 21433-2008 is the Chinese standard "Detecting susceptibility to intergranular corrosion in stainless steel pressure vessels".
Its scope clause reads: This standard applies manufacture stainless steel pressure vessel means a chromium content of not less than 16% of the acid-resistant steels, including austenitic stainless steel, ferritic Stainless steel and austenitic - ferritic stainless steel, but does not include martensitic stainless steel and precipitation hardening stainless steel.
Both pressure processing is not Stainless steel and welded joints, as well as stainless steel and the cladding layer.
This standard specifies both the requirements of intergranular corrosion susceptibility test itself stainless steel pressure vessel, also provides for the manufacture of stainless steel pressure vessel Is the corresponding inspection requirements stainless steel materials, welding materials and components by the Association.
This standard relates to intergranular corrosion means sensitized to intergranular corrosion, not including non-sensitized to intergranular corrosion. Its clauses include scope 1; normative references 1; terms and definitions 2.
