Compared with weather resistant S355J2WP steel, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while weather resistant S355J2WP steel is not.

Quenching Improve the hardness of weather resistant S355J2WP steel steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of weather resistant S355J2WP steel steel and comprehensive mechanical properties.
