00Cr17 material is added titanium and niobium based on 430 stainless steel, and then reduces the carbon content, thus improving the processing performance, and welding main corrosion resistance.
Often referred to by its Chinese GB standard, 00Cr17 is a high-performance ferritic stainless steel that offers an excellent combination of corrosion resistance, formability, and cost-effectiveness. It is essentially an ultra-low carbon and nitrogen version of Grade 430, enhanced with stabilizing elements like Titanium (Ti) or Niobium (Nb).
If you are searching for its internationally recognized equivalents like AISI 430, 439, UNS S43035, or the European grade 1.4510, you have found the right material.
This guide provides a complete technical overview of 00Cr17 stainless steel, covering its properties, equivalent grades, and primary applications to help you determine if it’s the right choice for your project.
Looking for industrial stainless steel with excellent weldability, cost-effectiveness, and resistance to intergranular corrosion? You’ve found the answer! 00Cr17 Material, as an outstanding representative of the new generation of ultra-low carbon, high-purity ferritic stainless steel, is rapidly becoming the best alternative to traditional 430 stainless steel in many demanding applications.

00Cr17 (AISI 430/S43035) Stainless Steel Data Sheet
Meaning of 00Cr17 Material
00Cr17 is a type of ultra-low carbon, high-purity ferritic stainless steel defined in the Chinese national standard (GB). The “00” in the designation represents its extremely low carbon content (< 0.03%), while “Cr17” indicates that its main alloying element is approximately 17% chromium (Cr).
Equivalent Grades of 00Cr17
One of the most critical steps in sourcing materials globally is understanding their international equivalents. 00Cr17 is the Chinese designation for a grade that is recognized worldwide under different standards.
| Standard | Equivalent Grade(s) |
| GB/T (China) | 00Cr17 (S11863) |
| AISI/ASTM (USA) | 430 / 439 / S43035 |
| JIS (Japan) | SUS430LX / SUS439 |
| DIN/EN (Europe) | X3CrTi17 / 1.4510 |
Although the above grades are very similar in performance, in actual procurement, a trace amount of Ti/Nb stabilization treatment (such as 1.4510) will further improve its high-temperature performance and weldability. Huaxiao Metal can recommend the most suitable 00Cr17 Stainless Steel or its international equivalent based on your specific project needs and budget.
As a leading steel supplier, Huaxiao Metal can provide 00Cr17 steel that meets the precise specifications of any of these international grades.

Key Features & Benefits of 00Cr17 Steel
Why choose 00Cr17 steel for your application? Its advantages go beyond the data sheet.
Excellent Weldability: The addition of stabilizing elements (Ti/Nb) and ultra-low carbon content means 00Cr17 can be welded without risk of intergranular corrosion, making it superior to standard Grade 430 for fabricated structures.
Good Corrosion Resistance: It offers strong resistance to atmospheric corrosion, oxidizing acids, and chloride-induced stress corrosion cracking, making it ideal for water tanks and home appliances.
Superior Formability: Its low carbon content gives it excellent ductility and deep-drawing capabilities, allowing it to be easily formed into complex shapes.
Cost-Effective Performance: As a ferritic stainless steel, it does not contain expensive nickel, making it a highly economical alternative to 300-series grades like 304 in many applications.
00Cr17 vs. 304 vs. 430 Stainless Steel: A Quick Comparison
Choosing the right grade is crucial for performance and budget. Here’s how 00Cr17 (as 439) compares to the most common austenitic (304) and ferritic (430) grades.
| Feature | 00Cr17 / 439 | AISI 304 | Standard AISI 430 |
| Cost | Low | High | Very Low |
| Corrosion Resistance | Good | Excellent | Fair |
| Weldability | Excellent | Excellent | Poor (Becomes Brittle) |
| Formability | Very Good | Excellent | Good |
| Magnetism | Magnetic | Non-magnetic | Magnetic |
| Typical Use | Welded parts, exhausts, water heaters | Food processing, chemical tanks | Decorative trim, non-welded parts |
Conclusion: If your application demands the highest corrosion resistance in acidic environments, 304 is the choice. If cost is the primary driver and no welding is involved, 430 may suffice. However, 00Cr17/439 is the ideal choice when you need a balance of good corrosion resistance, excellent weldability, and lower cost.
