SCMV6 ASTM Alloy Steel Plate A387 GR.5 CL.2 DISK PLATE For Boilers And Pressure Vessels
SCMV6 Standards ASTM A387 GR.5 CL.2, Alloy Steel Plate DISK PLATE For Boilers And Pressure Vessels
ASTM A387 grade 5 steel is an alloy steel formulated for primary forming into wrought products. ASTM A387 Grade 5 is the ASTM designation for this material. S50200 is the UNS number.
It has a moderately high electrical conductivity and a moderately high base cost among wrought alloy steels in the same category.
The properties of ASTM A387 grade 5 steel include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare ASTM A387 grade 5 steel to: wrought alloy steels in the same category (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
