DIPTI METAL INDUSTRIES
Leading 12Kh18N10T Stockist, 12Kh18N10T Supplier & 12Kh18N10T Exporter of GOST 12Х18Н10Т Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized 12Kh18N10T Supplier, 12Kh18N10T Exporter, and the foremost 12Kh18N10T Stockist of 12Х18Н10Т Titanium-Stabilized Austenitic Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. 12Kh18N10T (Cyrillic: 12Х18Н10Т) is the backbone of Russian GOST high-temperature engineering. Designed as the direct equivalent to AISI 321, it utilizes an 18% chromium and 10% nickel base, heavily fortified with Titanium. Because titanium binds with carbon far stronger than chromium does, it entirely prevents chromium carbide precipitation when the steel is heated into the sensitization range (400°C - 800°C). This renders 12Kh18N10T completely immune to intergranular corrosion (weld decay) during heavy structural welding and prolonged high-temperature service. It is the critical material for Eastern Bloc aerospace exhausts, chemical reactors, and high-pressure boiler tubes. We are a premier 12Kh18N10T Distributor supplying fully certified 12Kh18N10T Round Bars, Hex Bars, and Machined Forgings to the aerospace, petrochemical, and energy sectors worldwide.

📘 Technical Specifications: GOST 12Kh18N10T Engineering Profile
12Kh18N10T (12Х18Н10Т) is designed to solve the problem of intergranular corrosion at elevated temperatures. When standard stainless steels (like 304/12Kh18N9) are heated between 400°C and 800°C, the carbon steals chromium from the grain boundaries, causing the steel to rust and crack from the inside out. By alloying with Titanium (indicated by the 'T' / 'Т'), which has a much stronger affinity for carbon than chromium does, the carbon is safely bound as titanium carbides. This leaves the chromium fully available to maintain the steel's corrosion resistance, even during extreme heat cycling in jet engines or exhaust manifolds.
Metallurgical Composition Limits (GOST 5632-72)
| Element | Target (%) | Effect |
|---|---|---|
| Carbon (C) | ≤ 0.12 | Provides strength, safely bound by titanium |
| Chromium (Cr) | 17.00 - 19.00 | Provides the primary layer of oxidation resistance |
| Nickel (Ni) | 9.00 - 11.00 | Stabilizes austenite at high temperatures; ensures ductility |
| Titanium (Ti) | (5 x C) to 0.80 | Critical stabilizer; prevents sensitization & intergranular attack |
| Manganese (Mn) | ≤ 2.00 | Improves hot workability and structural integrity |
| Silicon (Si) | ≤ 0.80 | Enhances scaling resistance at elevated temperatures |
| Phosphorus & Sulfur | ≤ 0.035 / ≤ 0.020 | Strictly limited to ensure heavy weldment purity |
Mechanical Properties (Annealed Condition)
| Property | Typical Value Range |
|---|---|
| Ultimate Tensile Strength | ≥ 510 MPa |
| Yield Strength (0.2%) | ≥ 195 - 205 MPa |
| Elongation (δ5) | ≥ 40% |
| Hardness (HB) | ≤ 179 HB |
| Creep Resistance | Excellent continuous use up to 800°C |
| Weldability | Exceptional (Immune to weld decay) |
Our 12Kh18N10T Bars are supplied in the Solution Annealed condition. Because of the titanium stabilization, this grade retains exceptionally high creep strength and structural integrity even when exposed to long-term radiant heat.
