MATERIAL DESCRIPTION

 

why use stainless steel rebar?
COMPARE WITH EPOXY COATED REBAR

• 1 Excellent corrosion resistance property

• 2 No fear about the damage on the coating surface

• 3 Life cycle cost advantage

COMPARE WITH BLACK CARBON REBAR

• 1 Thinning concrete covering layer

• 2 Relaxing crack control

• 3 Lower carbon emission

• 4 Service life>250 years for concrete structures

duplex 2304 stainless steel reinforcement

2304 duplex stainless steel, also known as lean duplex stainless steel, possesses the same resistance to chloride ion corrosion as common austenitic stainless steel (316). It excels in stress corrosion resistance and offers outstanding mechanical properties, coupled with a lower reliance on nickel and molybdenum resources, making it a highly cost-effective choice. Thanks to its relatively stable pricing and excellent weldability, it has found widespread use in concrete structures for global engineering projects, accounting for over 95% of the global stainless steel rebar application proportion.
