What are the advantages of duplex stainless steel pipe fittings compared to 304/304L?
Dual phase stainless steel pipe fittings have the performance characteristics of both 304 and austenitic stainless steel pipe fittings.
What are the advantages of duplex stainless steel pipe fittings compared to 304/304L?
A. Dual phase stainless steel pipe fittings have excellent resistance to stress corrosion cracking, especially in environments containing chloride ions. Even dual phase stainless steel pipes with the lowest alloy content have higher resistance to stress corrosion cracking than austenitic stainless steel pipes. Stress corrosion is a prominent problem that ordinary austenitic stainless steel pipes are difficult to solve;
B. The corrosion resistance of duplex stainless steel pipe fittings, which are most commonly used in many media, is superior to that of ordinary 316L austenitic stainless steel pipes, while super duplex stainless steel pipes have extremely high corrosion resistance. In some media, such as acetic acid, formic acid, etc., they can even replace high alloy austenitic stainless steel pipes, and even corrosion-resistant alloys;
C. Compared with austenitic stainless steel pipes with equivalent alloy content, duplex stainless steel pipes have good resistance to local corrosion. Due to their high strength and good corrosion resistance, their wear resistance, corrosion resistance, and corrosion fatigue performance are superior to 304 stainless steel pipe fittings.
