Advantages of Stainless Steel

Stainless steel is one of the most widely used engineering materials due to its excellent corrosion resistance, durability, and versatility. It contains chromium as a key alloying element, which forms a protective oxide layer on the surface and helps prevent corrosion in many environments.

Instructions

1

Excellent High Temperature Resistance

Certain stainless steel grades maintain good mechanical properties and oxidation resistance at elevated temperatures.

Common Stainless Steel Grades

Different stainless steel grades are developed to meet specific performance requirements such as corrosion resistance

Austenitic Stainless Steel (Most Common Category)

Primarily alloyed with chromium and nickel, this type offers excellent corrosion resistance, formability, and weldability, and is non-magnetic or weakly magnetic.
304 (06Cr19Ni10)
The most widely used general-purpose stainless steel, containing 18% chromium and 8% nickel (also known as 18/8 stainless steel), suitable for food processing, kitchen equipment, architectural decoration, and other common environments.
304L (00Cr19Ni10)
An ultra-low carbon version with carbon content ≤0.03%, effectively preventing intergranular corrosion after welding, ideal for equipment requiring post-weld use.
304H
A high-carbon variant that enhances high-temperature strength, commonly used in automotive exhaust systems and high-temperature piping.
316 (06Cr17Ni12Mo2)
Adds molybdenum (Mo) to the 304 base, significantly improving resistance to chloride pitting corrosion, suitable for marine environments, chemical processing equipment, and medical devices.
316L (00Cr17Ni14Mo2)
An ultra-low carbon type with superior resistance to intergranular corrosion, widely used in thick-walled welded components in petrochemical industries.
316H
A high-carbon version that enhances high-temperature performance, suitable for high-temperature and high-pressure applications.
317L
Higher molybdenum content provides better resistance to organic acids (such as acetic and formic acid) than 316L, used in highly corrosive chemical environments.
321 (0Cr18Ni10Ti)
Stabilized with titanium (Ti) to prevent the precipitation of Cr₂₃C₆, improving resistance to intergranular corrosion, suitable for high-temperature welded components.
347 (0Cr18Ni11Nb)
Stabilized with niobium (Nb) instead of titanium, with performance similar to 321 and good weldability, used in thermal power and petrochemical industries.
904L (00Cr20Ni25Mo4.5Cu)
A super austenitic stainless steel with high nickel and molybdenum content, exhibiting exceptional resistance to non-oxidizing acids such as sulfuric and phosphoric acid, but with high cost, used only in extreme corrosive environments.

Ferritic Stainless Steel

High chromium content (12–30%), no nickel, low cost, magnetic, and resistant to chloride stress corrosion.
430 (1Cr17)
A common ferritic stainless steel used in appliance housings and architectural decoration, with moderate corrosion resistance.
409/409L
A low-cost titanium-stabilized type used in automotive exhaust systems.
436L / 444
With added molybdenum or niobium to enhance pitting resistance and weldability, used in water heaters and heat exchangers.

Martensitic Stainless Steel

Can be strengthened through heat treatment, high hardness, with moderate corrosion resistance, primarily used in cutlery, bearings, etc.
410 (1Cr13)
A basic martensitic steel used for general corrosion-resistant structural components.
420 (2Cr13 / 3Cr13)
Higher carbon content increases hardness, used in surgical instruments and cutlery.
440C (9Cr18MoV)
Hardness can reach HRC57, one of the hardest stainless steels, used in precision bearings, nozzles, and valve components.

Duplex Stainless Steel

A mixed microstructure of austenite and ferrite, combining high strength with excellent corrosion resistance, especially against chloride ion corrosion.
2205 (022Cr23Ni5Mo3N)
The most common duplex steel with strong resistance to chloride ion corrosion, used in seawater desalination and chemical piping.
2507 (S32750)
A super duplex steel with higher chromium, molybdenum, and nitrogen content, suitable for harsh marine and chemical environments.

Precipitation Hardening Stainless Steel

Achieves high strength through heat treatment while maintaining good corrosion resistance.
17-4PH (0Cr17Ni4Cu4Nb)
The most commonly used precipitation hardening steel, with strength up to HRC44, used in aerospace, offshore platforms, and other high-strength components.
630 / 631
Domestic equivalent grades, used in precision instruments and fasteners.

Other Common Grades

201 (1Cr17Mn6Ni5N)
Uses manganese to replace nickel, lower cost and higher hardness, used in architectural decoration and household hardware.
301
Strength significantly increases after cold working, used in railway vehicles and spring components.
303
With added sulfur and phosphorus to improve machinability, used in parts processed on automatic lathes.
310S (06Cr25Ni20)
High chromium and nickel content, resistant to temperatures up to 1200°C, used in furnace chambers and heat treatment equipment

Industries That Use Stainless Steel

Because of its balance of strength, corrosion resistance, and ease of fabrication, stainless steel is used across a wide range of industries including aerospace, medical equipment, chemical processing, marine engineering, and oil & gas.

Frequently Asked Questions About Stainless Steel
