What are the differences between No.10 seamless pipe and No.20 seamless pipe

No.10 seamless pipe is a seamless steel pipe with carbon content of 0.1%. It has good toughness and plasticity, and is often used for machining.

The difference between No.10 seamless pipe and No.20 seamless pipe:
1. The carbon content of No. 10 seamless pipe is 0.1%, while that of No. 20 seamless pipe is 0.2%.

2. The hardness of No.20 seamless pipe is higher than that of No.10 seamless pipe. Both are low carbon steels.

3. There is no stock for No.10 seamless pipe, but more specifications for No.20 seamless pipe. No.10 seamless pipe usually needs to book future products. That is, No.10 seamless pipe needs fresh production, and the delivery time is about 45 days.
