SS 303 Black Round Bar About

SS 303 is a free-machining austenitic stainless steel developed for excellent machinability. Its higher sulfur content makes it particularly suitable for high-speed machining and automatic screw-machine operations, although its corrosion resistance and weldability are generally lower than SS 304.

Applications: Automatic screw-machine components, shafts, nuts, bolts, fittings, bushings, gears and machined components.

Premium Quality for Demanding Applications

Each SS 303 Black Round Bar is produced through meticulous quality checks at every manufacturing stage, ensuring reliability and performance in critical applications. The combination of austenitic stainless steel chemistry and annealed or straightened temper provides a strong, tough product suitable for manufacturing components, shafts, fasteners, and precision fittings.

Versatility in Size and Manufacturing

Discover a wide range of diameters and lengths, from 10mm to 200mm, with the flexibility to request custom sizes tailored to project demands. The round bar's machinability is optimized for free machining applications, making it a favorite for manufacturers seeking both standard and non-standard dimensions for precision engineering tasks.

Durability with Trusted Sourcing

Sourced exclusively from HITRATNA METALS, the SS 303 Black Round Bar comes with the assurance of a reputable supplier. Its durable composition ensures long service life, with good corrosion resistance and heat resistance up to 870C intermittently. Choose standard export packaging or request customized packaging for secure, worldwide delivery.

FAQ's of SS 303 Black Round Bar:

A: Every SS 303 Black Round Bar undergoes rigorous quality checks throughout the manufacturing process, from sourcing raw materials to final inspection. This ensures that each batch meets ASTM standards and delivers consistent reliability for industrial applications.

Q: What are the primary benefits of using SS 303 Black Round Bar in machining applications?

A: This round bar offers excellent machinability, making it ideal for free machining operations. Its stable composition and precision tolerances support the production of complex components, reducing tool wear and enhancing productivity in manufacturing.

Q: When should I use SS 303 Black Round Bar for my project?

A: SS 303 Black Round Bar is best suited for projects where precision machining, moderate corrosion resistance, and durability are essential, such as manufacturing shafts, fasteners, fittings, and precision engineering components.

Q: Where can I get SS 303 Black Round Bar in custom sizes or export packaging?

A: Custom sizes and export-worthy packaging are available directly from HITRATNA METALS, the trusted supplier. You can specify exact dimensions and packaging preferences when placing your order to suit your particular needs.

Q: What should I know about the weldability and magnetism of SS 303 Black Round Bar?

A: Weldability of SS 303 is generally not recommended but can be performed using special procedures. In its annealed state, SS 303 is non-magnetic, but it may become slightly magnetic after cold working.

Q: How does the surface finish and composition benefit my industrial usage?

A: The black (hot rolled) matte finish offers a robust and wear-resistant surface, while the balanced stainless steel composition (including Cr 17-19%, Ni 8-10%, S 0.15-0.35%) delivers dependable mechanical properties and reliable corrosion resistance under demanding industrial conditions.
