Corrosion Resistant Steel (CRS)
Corrosion Resistant Steel (CRS) refers to alloy steels engineered to resist rust, oxidation, and chemical deterioration in aggressive environments. CRS is essential for industries such as oil & gas, petrochemical, marine, construction, and chemical processing, where long-term durability and low maintenance are critical.
At Hamiran Steel, we supply corrosion resistant stainless steel directly from Iran in forms such as sheets and sections, supporting both domestic and international buyers with export-ready service.
What Is Corrosion Resistant Steel?
Corrosion resistant steel is designed to withstand exposure to humidity, saltwater (chlorides), chemicals, and elevated temperatures. Its performance is achieved through alloying elements such as chromium, nickel, and molybdenum.
In most industrial projects, austenitic stainless steels like 316L (1.4404) and 304 (1.4301) are the most common CRS choices due to their strong corrosion resistance and fabrication versatility.
Types of Corrosion Resistant Steel
Ferritic Stainless Steels
Ferritic stainless steels, such as Grade 430, are chromium-based alloys offering moderate corrosion resistance. They are not heat-treatable but provide good performance in architectural and industrial applications.
Martensitic Stainless Steels
Martensitic grades like 410 gain strength through heat treatment. They offer higher hardness and wear resistance while maintaining moderate corrosion protection.
Austenitic Stainless Steels
Austenitic stainless steels such as 304 and 316 provide excellent corrosion resistance due to higher nickel content. They are widely used in chemical processing, marine, and food industries.
Duplex Stainless Steels
Duplex steels combine ferritic and austenitic microstructures, such as those found in Duplex 2205, offering high strength and improved resistance to pitting and crevice corrosion.
Super Duplex Stainless Steels
Super Duplex grades are highly alloyed versions of duplex steel, designed for extreme marine and offshore environments.
Nickel Base Alloys
Nickel-based alloys such as 625 and 825 offer exceptional resistance in highly corrosive chemical and offshore applications.
Corrosion Resistant Stainless Steel Grades We Supply

Stainless Steel Grades Available at Hamiran Steel
| Typical Uses | Corrosion Resistance Level | Stainless Family | AISI / Common Name | DIN Grade |
|---|---|---|---|---|
| Marine, offshore, chemical processing, chloride-rich environments | Very High | Austenitic | 316L | 1.4404 |
| Marine and industrial environments, chemical equipment | High | Austenitic | 316 | 1.4401 |
| Welded fabrication, food processing, general chemical service | High | Austenitic | 304L | 1.4306 |
| General industry, food equipment, architectural applications | Good | Austenitic | 304 | 1.4301 |
| Elevated temperature service, thermal cycling conditions | Medium–High | Austenitic (stabilized) | 321 | 1.4541 |
| High-temperature applications, energy and heat service | Medium | Austenitic | 304H | 1.4948 |
| Valves, industrial parts, moderate corrosion + strength needs | Medium | Martensitic | 410 | 1.4006 |
| High hardness components, wear-focused parts | Limited–Medium | Martensitic | 420 | 1.4021 |
| High strength components, specialized industrial applications | High | Precipitation Hardening | 17-7 PH | 1.4532 |
Quick selection tip:
• For maximum corrosion resistance, choose 316L (1.4404).
• For cost-effective general use, choose 304 (1.4301) or 304L (1.4306).
• For strength and wear priority, martensitic grades like 410/420 may be suitable (typically for less aggressive corrosion environments).
How to Choose the Right Corrosion Resistant Steel
When selecting a CRS grade, consider:
1. Environment: saltwater/chlorides, humidity, chemicals, temperature
2. Corrosion risk: pitting/crevice corrosion (often chloride-driven)
3. Fabrication: welding, machining, bending, polishing requirements
4. Mechanical needs: strength, hardness, wear resistance
5. Cost efficiency: choose the lowest grade that meets lifetime performance
Hamiran Steel provides technical guidance to help you select the best grade for your project.
