GB/T 226-2015
ActiveTest method for macrostructure and defect of steel by etching
钢的低倍组织及缺陷酸蚀检验法
Application Summary AI generated
This standard specifies the method for revealing the macrostructure and detecting defects such as porosity, segregation, cracks, and inclusions in steel samples through acid etching. It is primarily applied in the metallurgical industry for quality control during steel production, including ingot, billet, and rolled product inspection. The standard is used in laboratory testing to evaluate the internal soundness and homogeneity of steel, ensuring compliance with material specifications for structural, automotive, and heavy machinery applications.
