015Cr21Ni26Mo5Cu2 — stainless Steel: Composition, Properties & Applications
Also known as: 015Cr21Ni26Mo5Cu2
High-Mo austenitic, dilute H2SO4 & seawater resistant. (GB/T 20878; equiv UNS N08904 / EN 1.4539 / GB 015Cr21Ni26Mo5Cu2). Nominal values—confirm mill certificate.
CHEMICAL COMPOSITION
C:≤0.020;Cr:19.0-23.0;Ni:23.0-28.0;Mo:4.0-5.0;Cu:1.0-2.0
MECHANICAL PROPERTIES
Tensile:≥490 MPa;Yield:≥220 MPa;Elong:≥35%
TYPICAL APPLICATIONS
高钼奥氏体，耐稀硫酸海水。,"Plate
AVAILABLE FORMS
Bar
STANDARDS & EQUIVALENT GRADES
T 20878 015Cr21Ni26Mo5Cu2; GB 015Cr21Ni26Mo5Cu2; Heat input and interpass must be controlled to keep the ferrite/austenite balance; avoid exposure 300–400 °C (sigma) and use low carbon. Sensitive to chloride SCC above ≈60 °C.
HEAT TREATMENT
Duplex stainless steel with a mixed austenite/ferrite structure giving roughly twice the yield strength of austenitic grades plus excellent chloride resistance. Used in desalination, offshore, pulp & paper, heat exchangers and chemical tankage.
PROCESSING PRECAUTIONS
Solution anneal 1020–1100 °C and rapid quench; reheating near 300–400 °C (sigma phase) and 475 °C embrittlement zones must be avoided.
