DIPTI METAL INDUSTRIES
Leading 20Kh13 Stockist, 20Kh13 Supplier & 20Kh13 Exporter of GOST 20Х13 Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized 20Kh13 Supplier, 20Kh13 Exporter, and the foremost 20Kh13 Stockist of 20Х13 Martensitic Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. 20Kh13 (Cyrillic: 20Х13) is a foundational Russian GOST standard martensitic stainless steel. Serving as the direct equivalent to AISI 420, it features a 12-14% Chromium composition coupled with a slightly higher carbon content (~0.20%) than its 12Kh13 counterpart. This allows 20Kh13 to achieve significantly higher hardness (up to 50 HRC) and superior wear resistance when hardened by quenching and tempering. It is a vital alloy for Eastern Bloc power generation, high-stress pump shafts, turbine blades, and precision mechanical components. We are a premier 20Kh13 Distributor supplying fully certified 20Kh13 Round Bars, Hex Bars, and Machined Forgings to the heavy engineering, marine, and medical sectors worldwide.

📘 Technical Specifications: GOST 20Kh13 Engineering Profile
20Kh13 (20Х13) relies on the synergistic balance of 12-14% Chromium and ~0.20% Carbon. The chromium content provides standard stainless atmospheric and fluid corrosion resistance, while the elevated carbon (compared to 12Kh13) enables a more robust martensitic transformation upon quenching. This allows the material to attain high tensile strengths and a strong edge for industrial tooling or wear-resistant pump shafts.
Metallurgical Composition Limits (GOST 5632-72)
| Element | Target (%) | Effect |
|---|---|---|
| Chromium (Cr) | 12.00 - 14.00 | Provides foundational oxidation resistance and hardenability |
| Carbon (C) | 0.16 - 0.25 | Enables strong martensitic transformation for higher hardness |
| Nickel (Ni) | ≤ 0.60 | Residual limit, slightly supports toughness |
| Manganese (Mn) | ≤ 0.80 | Improves deep hardenability and hot workability |
| Silicon (Si) | ≤ 0.80 | Acts as a deoxidizer during the steelmaking process |
| Phosphorus (P) | ≤ 0.030 | Strictly limited to prevent brittleness |
| Sulfur (S) | ≤ 0.025 | Restricted to ensure exceptional fatigue life and cleanliness |
Mechanical Properties (Quenched & Tempered)
| Property | Typical Value Range |
|---|---|
| Ultimate Tensile Strength | ≥ 650 - 750 MPa |
| Yield Strength (0.2%) | ≥ 450 - 500 MPa |
| Elongation (δ5) | ≥ 15% |
| Reduction of Area (ψ) | ≥ 40% |
| Impact Toughness (KCU) | ≥ 50 J/cm² |
| Hardness (HB / HRC) | ~197 HB (Annealed) / up to 45-50 HRC (Hardened) |
Our 20Kh13 Bars are typically supplied in the annealed condition for optimal machinability. Fabricators will machine the parts to near-net shape, and then apply a quench (oil or air) and temper heat treatment to achieve the final high-strength and hardness characteristics.
