DIPTI METAL INDUSTRIES
Leading 03Kh18N11 Stockist, 03Kh18N11 Supplier & 03Kh18N11 Exporter of GOST 03Х18Н11 Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized 03Kh18N11 Supplier, 03Kh18N11 Exporter, and the foremost 03Kh18N11 Stockist of 03Х18Н11 Austenitic Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. 03Kh18N11 (Cyrillic: 03Х18Н11) is the premium low-carbon Russian GOST standard austenitic alloy. Equivalent to the highly versatile AISI 304L, the "03" designates a stringent maximum carbon limit of just 0.030%. By severely restricting carbon, 03Kh18N11 is rendered immune to intergranular corrosion (weld decay) during heavy, multi-pass welding, allowing massive structural components to be deployed without the need for post-weld solution annealing. With 18% Chromium and 11% Nickel, it offers phenomenal general corrosion resistance, deep-drawing formability, and brilliant cleanability. We are a premier 03Kh18N11 Distributor supplying fully certified 03Kh18N11 Round Bars, Sanitary Hex Bars, and Machined Forgings to the food processing, pharmaceutical, and chemical engineering sectors worldwide.

As a leading 03Kh18N11 Supplier in Mumbai, Dipti Metal Industries focuses on supplying high-purity materials for sanitary and heavily welded environments. Because 03Х18Н11 derives its corrosion resistance entirely from its ultra-low carbon chemistry (without using titanium or niobium stabilizers), we source our steel exclusively from Certified Tier-1 Mills utilizing precise Argon Oxygen Decarburization (AOD). This guarantees an inclusion-free, perfectly homogenized austenitic matrix that polishes to a flawless sanitary finish.

📘 Technical Specifications: GOST 03Kh18N11 Engineering Profile
03Kh18N11 (03Х18Н11) solves the primary flaw of standard 304 (12Kh18N9) stainless steel: sensitization during welding. By keeping the carbon content at or below 0.030%, there is simply not enough carbon present to bond with chromium when the steel is heated to 425°C–815°C. This means the chromium stays in the grain matrix, fully protecting the metal from rust and chemical attack at the weld seams. Furthermore, the 11% nickel content keeps the steel highly ductile, allowing for extreme deep drawing and spinning.
Metallurgical Composition Limits (GOST 5632-72)
| Element | Target (%) | Effect |
|---|---|---|
| Carbon (C) | ≤ 0.030 | Ultra-low limit prevents sensitization and weld decay |
| Chromium (Cr) | 17.00 - 19.00 | Provides the foundation for oxidation and corrosion resistance |
| Nickel (Ni) | 10.00 - 12.00 | Stabilizes the austenitic structure and enhances formability |
| Manganese (Mn) | ≤ 2.00 | Improves hot workability and structural integrity |
| Silicon (Si) | ≤ 0.80 | Enhances scaling resistance at elevated temperatures |
| Phosphorus (P) | ≤ 0.035 | Strictly limited to prevent cold embrittlement |
| Sulfur (S) | ≤ 0.020 | Restricted to ensure surgical-grade purity and clean polish |
Mechanical Properties (Annealed Condition)
| Property | Typical Value Range |
|---|---|
| Ultimate Tensile Strength | ≥ 480 MPa |
| Yield Strength (0.2%) | ≥ 195 MPa |
| Elongation (δ5) | ≥ 40% |
| Hardness (HB) | ≤ 170 HB |
| Cryogenic Toughness | Excellent down to -196°C |
| Magnetic Properties | Non-Magnetic (Annealed) |
Our 03Kh18N11 Bars are supplied exclusively in the Solution Annealed condition. Because it lacks carbon, its baseline yield strength is slightly lower than standard 12Kh18N9, but this trade-off provides vastly superior cold-forming and welding capabilities.
