OTHER GRADES

Overview and Applications

303, 416, and 440C stainless steel square bar, along with heat-treated 4130 alloy steel and brass square bar, are engineered to meet diverse structural, machining, and mechanical performance requirements. These square bar grades are commonly used for frames, supports, brackets, tooling components, precision machined parts, and industrial assemblies. Each material is selected based on its strength, machinability, corrosion resistance, or wear performance to suit specific fabrication and engineering applications.

Performance & Material Advantages

303 and 416 stainless steel square bars provide enhanced machinability for high-speed CNC operations, while 440C stainless steel offers high hardness and wear resistance for tooling and mechanical components. Heat-treated 4130 alloy steel delivers strong structural performance and toughness for load-bearing applications, and brass square bar provides excellent machinability and corrosion resistance for decorative and precision uses. These alternative square bar grades ensure reliable performance, dimensional accuracy, and fabrication efficiency across industrial and commercial environments.

Technical Specifications

Stainless steel, alloy steel, and brass square bars are manufactured in accordance with applicable ASTM standards to ensure consistent chemical composition and reliable mechanical performance. Available grades include 303 and 416 stainless steel for enhanced machinability, 440C stainless steel for high strength and wear resistance, heat-treated 4130 alloy steel for structural applications, and brass square bar for precision machining and decorative uses. These square bars are supplied in hot-rolled and cold-finished conditions, offering dimensional accuracy and smooth surface finish.
