- Product Details
S31803 duplex stainless steel pipe is a kind of medium alloy two-phase stainless steel with good resistance to chloride stress.Medium alloy type -- UNS S31803 (22cr-5ni-3mo-0.15n);The S31803 dual-phase steel pipe is the most widely used in three types of dual-phase steel (2205 dual-phase stainless steel pipe, 2507 duplex stainless steel pipe and S31803 dual-phase stainless seamless pipe).
S31803 duplex stainless steel tube features
PREN value 32 ~ 33
The corrosion resistance of medium alloy UNS S31803 is between AISI 316L and 6%Mo+N austenitic stainless steel.
The yield strength is more than 2 times of type 18-8 austenitic stainless steel.
