Interpretation of steel grade 20YuChA
Explanation of steel 20YuChA: Structural high-quality carbon steels are produced in converters or in open-hearth furnaces. The designation of these steel grades begins with the word “Steel”. The next two numbers indicate the average carbon content in hundredths of a percent; the numbers 20 indicate a content of about 0.2 percent. The letter Y indicates that the aluminum content in the steel is up to 1%, the letter H is the content of rare earth metals in the alloy up to 1%, and the letter “A” indicates that the steel is high-quality with a phosphorus and sulfur content of less than 0.025%. Contamination of steel grade 20YuChA with non-metallic inclusions should not exceed line oxides (OS) - point 3; for sulfides (C) - point 3. Contamination with sulfides on one sample is allowed no more than point 4.
