DIPTI METAL INDUSTRIES
Leading 03Kh22N5M3 Stockist, 03Kh22N5M3 Supplier & 03Kh22N5M3 Exporter of GOST 03Х22Н5М3 Duplex Steel in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized 03Kh22N5M3 Supplier, 03Kh22N5M3 Exporter, and the foremost 03Kh22N5M3 Stockist of 03Х22Н5М3 Duplex Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. 03Kh22N5M3 (Cyrillic: 03Х22Н5М3) is a premium Russian GOST standard austenitic-ferritic (duplex) stainless steel. Due to its biphasic microstructure and high levels of Chromium and Molybdenum, it delivers roughly double the yield strength of standard austenitic grades (like 304/316) while offering extraordinary resistance to localized pitting and chloride stress corrosion cracking (SCC). It is heavily utilized in Eastern Bloc offshore rigs, subsea architecture, and chemical processing facilities. We are a premier 03Kh22N5M3 Distributor supplying fully certified 03Kh22N5M3 Round Bars, Hex Bars, and Machined Forgings to petrochemical and marine sectors worldwide.

📘 Technical Specifications: GOST 03Kh22N5M3 Engineering Profile
03Kh22N5M3 (03Х22Н5М3) is a low-carbon, nitrogen-alloyed duplex steel. The "03" denotes ultra-low carbon (≤0.03%), which prevents carbide precipitation during welding. The ~22% Chromium and ~3% Molybdenum provide excellent protection against pitting and crevice corrosion, while Nitrogen enhances strength and aids in reforming austenite in heat-affected zones.
Metallurgical Composition Limits (GOST)
| Element | Target (%) | Effect |
|---|---|---|
| Chromium (Cr) | 21.00 - 23.00 | Provides foundational oxidation and high pitting resistance |
| Nickel (Ni) | 4.50 - 6.50 | Stabilizes the dual-phase (austenite/ferrite) structure |
| Molybdenum (Mo) | 2.50 - 3.50 | Drastically improves resistance to chloride environments |
| Nitrogen (N) | 0.08 - 0.20 | Increases yield strength and promotes austenite formation |
| Carbon (C) | ≤ 0.030 | Ultra-low limit prevents intergranular corrosion |
| Manganese (Mn) | ≤ 2.00 | Improves hot workability |
| Silicon (Si) | ≤ 1.00 | Deoxidizer, enhances scaling resistance |
Mechanical Properties (Solution Annealed)
| Property | Typical Value Range |
|---|---|
| Ultimate Tensile Strength | ≥ 680 - 880 MPa |
| Yield Strength (0.2%) | ≥ 450 MPa |
| Elongation (δ5) | ≥ 25% |
| Hardness (HB) | ≤ 290 HB |
| Pitting Resistance (PREN) | ≥ 34 - 36 |
| Impact Toughness (KCU) | ≥ 80 J/cm² |
Our 03Kh22N5M3 Bars are supplied in the Solution Annealed condition, maximizing both ductility and corrosion resistance. The duplex structure provides double the yield strength of standard 304/316, allowing for thinner, lighter component design.
03Kh22N5M3 Cross-Reference & Global Equivalents
While 03Kh22N5M3 is the specific Russian/CIS designation, this biphasic metallurgical profile is identical to the world’s most popular duplex stainless steel grade.
