I would like to ask what the meaning of K is in Q235-B(K)
Thread Content
In production, I encountered the pipe material Q235-B(K); I’m not sure what the ‘K’ means Experts, please give your advice!
Does it mean Kill (quenched steel)?
:) In the pipe material Q235-B(K), the letter K is the uppercase form of the pinyin character for “kuo”; it is not the meaning of \"Kill\" as mentioned on the second floor. The letters in our steel product codes are all uppercase pinyin characters, not those with their English meanings. The designation Q235-B(K) for pipe material refers to steel pipes manufactured using the hot-expanded seamless method; in addition, there are also methods such as hot drawing, cold drawing, and hot extrusion
What was said on the 3rd floor makes sense; it should be thermal expansion
In the pipe material Q235-B(K), the letter K is the capital letter at the beginning of the pinyin character for \"kuo\"; if it were a steel grade, it should be the capital letter at the beginning of the character for \"kuang\", indicating that it is steel designed for use in mining applications
