Our Product Range

the leading stockiest, importers, exporters & suppliers of ASME SA 387 GRADE 9 Class 2

ASME SA 387 GRADE 9 Class 2


A weldable carbon steel plates for pressure vessels and boilers used in elevated temperatures. The material benefits from added chromium and molybdenum which gives the steel greater corrosion resistance and resistance to heat. SA387 Grade 9 is used by fabricators who serve the oil, gas and petrochemical industry.

ASME SA387 Grade 9 Class 2 is available ex stock form our UK warehouse and we can dispatch to clients on a global basis. As with all our carbon steel plates, the material comes with mill certification and stampings.
