ASTM A387-2-1 pressure vessel Cr Mo alloy steel sheet Width
The reason ASTM A387-2-1 pressure vessel Cr Mo alloy steel sheet is so popular is that chrome moly steel plate is strong and formable. So A387-2-1 pressure vessel Cr Mo alloy steel sheet can be easily formed into pipes and fittings and rolled into pressure vessels and boilers without either the cost or the cracking that isseen in other materials
ASTM A387-2-1 Cr Mo alloy steel sheet is alloy steel plate that is designed for use in pressure vessels, process vessels and boilers operating at high temperatures.
ASTM A387-2-1 Specification:
Thickness:6-300mm
Width:1500-4050mm
Length:3000-15000mm
