Method for measuring hardness of carbon steel
When choosing a suitable method for measuring the hardness of carbon steel, you need to pay attention to the supply status of the steel and the requirements for measurement accuracy. Generally speaking, the indentation method is suitable for steel in the annealed or normal state, and the rebound method is suitable for steel in the cold drawn state. No matter which method is used, you need to pay attention to the measurement skills and the stability of the experimental environment in order to obtain accurate hardness values.

ASTM A135 GR.A ERW Steel Pipe/tube
The ASTM A135 ERW steel pipes are intended for conveying gas, vapor, water or other liquid; only Grade A is adapted for flanging and bending. The selection of this ERW pipe for various applications depends on its dimensions, properties, and conditions of service. The pipe may be furnished either non-expanded or cold expanded at the option of manufacturer. When pipe is cold expanded, the amount of expansion shall not exceed 1.5% of the outside diameter of pipe size.
