What is the heat treatment specification of S690Q material properties

Strong pressure resistance of S690Q material properties, boiler steel tube: The wall thickness of boiler steel tube is very important, because the steam pressure is very large, if the wall thickness is very thin, it will be broken by the steam pressure released instantly. The boiler steel tube has good high temperature resistance performance: the steam temperature in the pipeline can reach hundreds of degrees Celsius above. If the high temperature resistance performance is not enough, the boiler steel tube will be melted by the high temperature brought by the steam.

Semi-endless rolling technology has three advantages: the S690Q material properties product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.
