SUS304 Description :

SUS304 is the most widely used steel grade as a typical garde of austenitic stainless steel and is a material with very good market availability. It is widely used for various applications because of its good balance of mechanical properties and corrosion resistance.
While not as strong as SUS301, it is possible to increase its strength by cold rolling, and can be used for spring components.
In addition, annealed or lightly rolled finishes have higher elongation and can withstand complex processing.

We supply a variety of stainless steels for springs as specified in JIS G4313.

Wide Application Versatility
SUS304 stainless steel is engineered for a wide range of high-performance applications, including electronics, automotive, medical, and industrial sectors. Its stability and adaptability make it ideal for use in FPCs, shielding components, heating elements, and precision hinges, providing a durable solution tailored for cutting-edge technologies.

Multiple Forms and Finishes Available
Offered as coils, sheets, wires, bars, and pipes, in both bright and dull finishes, SUS304 ensures manufacturers can select the precise specification needed. Each form is engineered to maintain integrity under high-stress conditions, making it perfect for springs and components requiring consistent performance and longevity.

BIS Certified for Quality Assurance
This stainless steel is BIS certified, ensuring it meets rigorous Indian and international quality standards. Manufacturers, suppliers, and exporters in Japan adhere to stringent production and inspection practices to guarantee material consistency, optimal performance, and compliance with global requirements.

FAQ's of SUS304 - UNS S30400 | Stainless Steel for Springs *BIS certified product:

Q: How is SUS304 stainless steel manufactured for use in springs and precision parts?

A: SUS304 stainless steel for springs undergoes precise cold rolling and annealing processes to achieve desired thicknesses and tempers such as Bright Annealed (BA), skin passed (2B), and various hard conditions (1/2H, 3/4H, H). These production steps ensure a uniform structure, mechanical strength, and surface finish suitable for demanding applications.

Q: What are the ideal applications for SUS304 stainless steel in the electronics and automotive industries?

A: SUS304 stainless steel is widely used in vibration motors, flexible printed circuits (FPC), shield cases, printers, variable resistors, and other precise components. Its combination of flexibility and strength makes it well-suited for parts like syringe needles, razor blade guards, chains, injectors, and oil rings found in automotive and electronic products.

Q: When should manufacturers choose SUS304 stainless steel for their products?

A: Manufacturers should select SUS304 when their applications demand a blend of corrosion resistance, mechanical strength, and formability. It is especially advantageous where components will experience repetitive motion or require precise mechanical properties, such as in springs, hinges, and moving electrical contacts.

Q: Where is SUS304 - UNS S30400 stainless steel manufactured and supplied from?

A: This grade of stainless steel is manufactured to strict quality standards in Japan, and is exported globally by certified manufacturers and suppliers. It meets international specifications and certifications, such as BIS, ensuring reliable material quality and performance.

Q: What are the available shapes and surface finishes for SUS304?

A: SUS304 is supplied in coil, sheet, wire, bar, and pipe forms. Surface finishes range from bright (BA), dull, to skin passed (2B), accommodating diverse application needs from aesthetic components to industrial assemblies.

Q: How does SUS304 stainless steel benefit manufacturers and end-users?

A: SUS304 offers manufacturers exceptional workability, durability, and resistance to corrosion, reducing maintenance and replacement costs. End-users benefit from products with extended lifespans and consistent performance, ensuring long-term reliability in challenging environments.
