13Х9М (13Kh9M) WP9 Alloy Steel Pipe Fittings | Elbow, Tee, Reducer, Cap
What Are 13Х9М (13Kh9M) Pipe Fittings?
13Х9М (13Kh9M) alloy steel pipe fittings are high-temperature Cr-Mo alloy fittings equivalent to ASTM A234 WP9 (9Cr-1Mo) material. These fittings are widely used in power plants, oil refineries, petrochemical industries, and high-pressure piping systems.
Manufactured according to international standards such as ASTM, ASME, DIN, and GOST, 13Х9М pipe fittings provide excellent performance in high temperature and high pressure environments.
Equivalent Standards
13Х9М alloy steel is recognized as an equivalent material to WP9 in various international standards.
| Standard | Grade |
|---|---|
| ASTM / ASME | A234 WP9 / A335 P9 |
| EN | 1.7386 (X12CrMo9-1) |
| DIN | 10CrMo9-10 |
| GOST | 13Х9М (13Kh9M) |
