Steel plate for for Boiler Pressure Vessel UNE 36087 A37 RCI
UNE 36087 A37 RCI steel grade is one of grade in UNE 36087, which is non alloy and alloy steels with specified elevated temperature properties.The composition of this steel makes it ideal for applications where elevated working temperatures are the norm and the material is used by fabricators throughout the oil, gas and petrochemical industry.
UNE 36087 A37 RCI steel is a normalized carbon alloy steel and is available ex-stock from our warehouse with mill certification and stamping. This UNE 36087 steel grade supersedes the older BS and DIN standards
