As an metal casting manufacturer in China, how can we convert the foreign standard of grey iron (gray iron) castings into the standard in China?

The following comparison table will be a good reference for us. This table listed various grey iron grades in China, Japan, USA, Germany, Russia, Italy, France, England and ISO standard etc. However, this table is just an approximate comparison for metal casting manufacturers, you can not take it as the inspection standard. However, this table is very useful for inquiry and making quotations. Therefore, the suppliers and buyers can easily reach a consensus for the material requirements.
