But the processing worker can take it as reference depend on the processing's part in production line.
How about the application for 1020 mild steel in the actual production ?
1020 steel will be applied to the make the shaft, ratchet, gear part for industrial. AISI1020 carbon steel can not be common to found at any time in the Chinese marketing because of using it with less group in China local factory And the most importance reason is that its price is not high, which will cause that many steel mills are not willing to produce this steel grade.
Instead, many people prefer to choose 1045 carbon steel for machining parts that can be met the missing parts of their processing machine. Even the part with broken, it can be easily to find the replace one in nearly industry area right now.
