What is the equivalent of 1.4510 stainless steel?
1.4510 is a ferritic stainless steel with excellent weldability and corrosion resistance, stabilized with titanium. It is known by other designations like AISI 439 and UNS S43035, and is frequently used in applications such as automotive exhaust systems, and in the food and dairy industry. Its titanium content makes it resistant to intergranular corrosion, and it is suitable for both hot and cold forming.

Comparison Table: 439 vs. 430 vs. 304
| Grade | Corrosion Resistance | Formability | Cost | Best For |
|---|---|---|---|---|
| 439 | Good (stabilized) | Excellent | Low-Medium | Automotive exhausts |
| 430 | Moderate | Good | Low | Decorative trims |
| 304 | Excellent (austenitic) | Very Good | High | Marine/chemical environments |
Applications
Stainless Steel 439 is widely used in industries requiring moderate corrosion resistance and high formability:
Automotive: Exhaust systems, catalytic converters, mufflers.
Appliances: Dishwashers, washing machines, oven linings.
Construction: Roofing, wall panels, HVAC components.
Industrial: Heat exchangers, tanks, agricultural equipment.
Surface
Acid pickling – pre-passivation process of treating stainless steel parts with an acid solution, typically hydrochloric or sulfuric acid, which can remove oxide scale and heat tint while dissolving steel flecks embedded in the part.
Polishing – P grade sandpaper: P150, P200, P250, P300, P400, P500, P600, P700, P800
