• Description

201 Stainless steel is an austenitic stainless steel, the main components include chromium,nickel, manganese and other elements. It has good corrosion resistance and plasticity, excellent processing performance, and it is suitable for stamping, bending, and other processing processes. Compare with 304 stainless steel, 201 stainless steel has lower nickel content and higher manganese content, so the cost is relatively low and cost effective. It is often used in architectural decoration, kitchen equipment, home applicance housing and other fields. However, the corrosion resistance of 201 stainless steel is slightly inferior to that of 304, and it is not suitable for long-term contact with strong acidic or alkaline environments.

• Features

Excellent Machinability

• Excellent Machinability

→ 201 stainless steel is an austenitic stainless steel with good machinability, making it suitable for a wide range of machining processes, including CNC turning, milling, and drilling. Its manganese-rich composition enhances its workability compared to higher nickel steels, reducing tool wear and improving chip formation.

→ This grade is ideal for applications requiring moderate precision and surface finish, such as manufacturing components for consumer goods, kitchenware, and light industrial equipment.

→ The relatively lower nickel content in 201 stainless steel also contributes to its cost-effectiveness while maintaining good machinability, making it a popular choice for high-volume production.

• Shapes

Round bars, coils, plates, flat, pipes/tubes.

• Application

201 Stainless steel has been widely used in many fields due to its good strength,corrosion resistance and economy.
