American Standard Standard for Seamless Steel Pipe ASTM A210--- American Society for Testing and Materials Standard ASME SA210--- American Society of Mechanical Engineers Standards.
SA210C seamless steel pipe use: suitable for boiler tubes and boiler flue tubes, including safety ends, vault and support tubes, and superheater tubes with small wall thickness seamless medium carbon steel tubes.
The main production of American standard steel pipes is A210A1, A210C, etc.

September is the traditional peak season of SA210C high-pressure boiler tubes, however, more than half of the "Golden Nine", SA210C high-pressure boiler tube market has not come out of expectations, but with this week, many institutions continue to be bullish on SA210C high-pressure boiler tube industry after the peak season.
The data shows that the national market ** continued to fall slightly last week. Since the beginning of last week, the goods have hit the confidence of manufacturers all the way, coupled with the downstream demand is less than expected, the social inventory is high, and the SA210C high-pressure boiler tube has continued to fall. Approaching the end of last week, the goods have come out of the big dive of five consecutive clouds.
However, September is the traditional peak season for SA210C high-pressure boiler tubes, however, this year's "Golden Nine" market has come out of the "cold tone". Since September, the domestic SA210C high-pressure boiler tube operation is weak, the demand side is not enough to follow up, the market price has shown the highest quality, and the steel mills have repeatedly supported the price, the reason is that the cost of raw materials such as iron ore and coke is the most important supporting force for steel mills. On the one hand, the demand is insufficient, the SA210C high-pressure boiler tube is declining, and the shipment is poor, on the other hand, the cost of enterprises is rising, and the market contradictions are accumulating.
In terms of cost, as the cost of iron ore, coke, alloy and other raw materials continues to rise, the cost of steel mills continues to increase, which continues to put pressure on steel mills.
