Product
 3CR12
is a weldable chromium containing utility
stainless steel, with a fine grained duplex ferritic-martensitic
microstructure.
Application
3CR12 is a particularly recommended
for use on moderately aggressive
environments found in the construction,
industrial, marine, mining and mineral
processing fields. It provides a cost
effective solution to corrosion,
oxidation and corrosion/abrasion
problems in a wide range of
environments. Typical examples
include:
• Ore Cars
• Pipe & Tube for Slurry Handling
• Coal Chutes and Liners
• Storage Bins and Hoppers
• Locomotive Bodies
• Ash Handling
• Masonry Fixings
• Coal Wash Plant Structure
• Conveyor Decking
• Sand – Chutes Dredging
• Screw Conveyors
ELEVATED TEMPERATURE PROPERTIES
Like other chromium stainless steel,
3CR12 has useful strength at
temperature about 600oC. This ele
vated temperature strength is significantly higher than that of plain-carbon steels. Hot working can be
carried out at 700ºC - 800ºC without
significantly affecting subsequent
mechanical properties.
Above 850ºC, 3CR12 behaves
superplastically due to the fine
grained duplex microstructure.
