Cad iad na hiarratais chuí do 16MnCr5 agus Q355B? An féidir leis an dá neart carburizing 58-62 HRC a bhaint amach?

A: Is féidir Q355 a bhaint amach trí phróisis chóireála teasa optamaithe.
Ábhar Cruas Dromchla (HRC) Croí-chruas (HRC) Doimhneacht an Chiseal Cruaite (mm) Oiriúnacht
16MnCr5 58-62 28-35 0.8-1.5 Giaranna tromshaothair, seaftaí tarchurtha
Q355B 40-45 (optamaithe ≤50) <20 0.3-0.6 (neamhéide)

Roimhe Seo:

What material is used for the inner frame of the paving bricks? Is it 16MnCr5 (German board) or Q355B (domestic board)? Can both achieve a carburizing strength of 58-62 HRC? According to information found on Chatgpt, the former can achieve a carburizing strength of 58-62 HRC, but the latter is around 55-60 HRC. If a customer inquires, it will cause distrust and doubt.
