What is 301 Stainless Steel?
301 stainless steel (UNS S30100, also known as SUS301 under JIS standards and 1.4310 under EN standards) is a high-strength austenitic stainless steel renowned for its exceptional work-hardening capability. As a metastable austenitic grade, 301 develops significantly higher tensile strength through cold working than other stable austenitic grades. Its lower nickel content (6–8%) compared to 304 stainless steel promotes rapid work-hardening and deformation-induced martensitic transformation, enabling mechanical strength levels far exceeding those of common austenitic grades.
Chemical Composition of 301 Stainless Steel (JIS G4313-2011 / SUS301-CSP)
Per JIS G4313-2011 standard for cold rolled stainless steel strip for springs, the chemical composition of SUS301-CSP is as follows:
| Element | Composition (wt.%) |
|---|---|
| Carbon (C) | ≤ 0.15% |
| Silicon (Si) | ≤ 1.00% |
| Manganese (Mn) | ≤ 2.00% |
| Phosphorus (P) | ≤ 0.045% |
| Sulfur (S) | ≤ 0.030% |
| Chromium (Cr) | 16.00 – 18.00% |
| Nickel (Ni) | 6.00 – 8.00% |
This carefully balanced alloy composition gives 301 stainless steel its outstanding combination of corrosion resistance, high strength, and excellent formability.
Mechanical Properties of 301 Stainless Steel – Soft Condition
In the annealed (soft) condition, 301 stainless steel exhibits the following mechanical properties:
| Property | Value (Soft / Annealed) |
|---|---|
| Tensile Strength (Rm) | ~515 – 650 MPa |
| Yield Strength (Rp0.2) | ~205 – 250 MPa |
| Elongation | ≥ 40 – 45% |
| Hardness | ~200 HV / ≤ 95 HRB |
The soft condition of 301 stainless steel strip allows for deep drawing and forming without cracking. Through subsequent cold working, 301 can achieve tensile strengths exceeding 1,500 MPa, making it one of the most versatile stainless steel grades available.
Key Properties of 301 Stainless Steel
-
High Work-Hardening Rate: 301 stainless steel can more than triple its strength through cold deformation
-
Excellent Corrosion Resistance: Withstands corrosion from most oxidizing acids and atmospheric conditions
-
Good Ductility: Maintains formability even at high strength levels
-
Temperature Resistance: Usable up to approximately 300°C
-
Austenitic Structure: Non-magnetic in annealed condition, becomes magnetic after cold working
