ASME SA 53 seamless pipe is manufactured according to S690QL1 material equivalent ASME code. Because it belongs to low carbon steel, the surface hardness can only be improved by carburizing. If you are interested in BBN S690QL1 material equivalent ASTM A53 or ASME SA 53 carbon seamless pipe, please contact us for the latest price.

Nickel element is mainly used to form and stabilize the austenite structure, so that the S690QL1 material equivalent steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
