📘 Technical Specifications: GOST 12Kh13 Engineering Profile
12Kh13 (12Х13) is a core martensitic stainless steel. Its nominal 12% chromium content provides the base level of corrosion resistance required for it to be classified as stainless. However, its true value lies in its 0.09% - 0.15% carbon content, which allows the material to be quenched and tempered to high hardness levels, providing an excellent balance of strength, impact toughness, and wear resistance.
Metallurgical Composition Limits (GOST 5632-72)
| Element | Target (%) | Effect |
|---|---|---|
| Chromium (Cr) | 12.00 - 14.00 | Provides foundational oxidation resistance and hardenability |
| Carbon (C) | 0.09 - 0.15 | Enables martensitic transformation for high strength/hardness |
| Nickel (Ni) | ≤ 0.60 | Residual limit, slightly supports toughness |
| Manganese (Mn) | ≤ 0.80 | Improves 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 | ≥ 490 - 640 MPa |
| Yield Strength (0.2%) | ≥ 340 MPa |
| Elongation (δ5) | ≥ 20% |
| Reduction of Area (ψ) | ≥ 50% |
| Impact Toughness (KCU) | ≥ 59 - 78 J/cm² |
| Hardness (HB) | ~143 - 212 HB (Annealed) / up to 45 HRC (Hardened) |
Our 12Kh13 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 and temper heat treatment to achieve the final desired mechanical strength and hardness.
12Kh13 Cross-Reference & Global Equivalents
