AISI 201 Stainless Steel Tube SUS201 1.4372

201 Stainless Steel Pipe/Tube Details

Overview

201 stainless steel pipe/tube is a versatile and cost-effective material used in a variety of applications. This alloy is a type of austenitic stainless steel that provides a balance of strength, corrosion resistance, and formability. It is particularly valued for its good mechanical properties and relative affordability compared to other stainless steels.

Key Characteristics

Corrosion Resistance: Offers moderate resistance to corrosion in mildly corrosive environments. Not as resistant as 304 or 316 stainless steels but suitable for many general applications.

Formability: Exhibits good formability, allowing it to be easily fabricated into various shapes and sizes.

Strength: Provides good tensile and yield strength, making it suitable for structural applications.

Magnetic Properties: Shows some magnetic properties, especially in the cold-worked condition, unlike most other austenitic stainless steels.

Cost-Effective: Typically less expensive than 304 and 316 grades due to its lower nickel content.

Chemical Composition

Carbon (C): ≤ 0.15%

Manganese (Mn): 5.50-7.50%

Silicon (Si): ≤ 1.00%

Phosphorus (P): ≤ 0.060%

Sulfur (S): ≤ 0.030%

Chromium (Cr): 16.00-18.00%

Nickel (Ni): 3.50-5.50%

Common Applications

Construction: Used in construction and architectural applications for structural support and decorative elements.

Automotive Industry: Employed in automotive parts, exhaust systems, and trim due to its strength and formability.

Piping Systems: Suitable for general piping applications where moderate corrosion resistance and good mechanical properties are required.

Furniture: Used in manufacturing furniture, including tables and chairs, for its aesthetic appeal and durability.

Industrial Equipment: Applied in various industrial settings, including machinery and equipment where cost-effectiveness and performance are key.

Advantages

Good Corrosion Resistance: Provides adequate resistance to corrosion for many general applications, though not suitable for highly corrosive environments.

Versatile Formability: Can be easily formed into various shapes and sizes, making it suitable for a wide range of applications.

Strength: Offers good mechanical strength, making it a reliable choice for structural and load-bearing applications.

Cost-Effective: More affordable compared to higher-grade stainless steels like 304 and 316, offering a balance of performance and cost.

Magnetic Properties: Can be advantageous in applications where magnetic properties are desired.

Summary

201 stainless steel pipe/tube is a practical and economical choice for various applications requiring good strength, formability, and moderate corrosion resistance. Its chemical composition provides a balance of performance and cost, making it suitable for use in construction, automotive parts, piping systems, furniture, and industrial equipment. While it does not offer the same level of corrosion resistance as some other stainless steels, its affordability and versatility make it a valuable option for many applications.
