GB/T 3620.2:2023 Titanium and titanium alloy permissible variations of chemical composition for wrought product analysis
1 Scope
This document specifies the permissible variations of chemical composition of titanium and titanium alloy wrought products (plates, strips, foils, pipes, bars, wires, forgings, profiles, castings).
This document is applicable to check analysis and arbitration analysis of chemical composition of products by the purchaser.
This document is not applicable to the analysis of the chemical composition of the product by the supplier, nor to the check analysis of the change of the content of impurity elements (such as hydrogen, nitrogen and oxygen) caused by the reprocessing of the product by the purchaser.
2 Normative references
