What shapes are available besides round bar?

In addition to round bars, we can support flat bars, square bars, rings, hollow sections, blocks and special shapes depending on specification and sourcing.

What size range and finishes are typical?

Typical diameters are from 6 mm to 230 mm with lengths up to 12 m. Finishes can include 2B, BA, hairline, No.1, No.4 and mirror depending on requirements.

What should I include in an RFQ?

Please include grade/standard, shape, diameter/size, length, surface finish, quantity, any processing (e.g., centerless grinding) and required documents (MTC) plus destination.

ASEA METAL supplies stainless steel round bar and special shapes in Korea for machining and fabrication. Multiple grades, finishes and processing options with documentation support for export projects. We supply stainless steel round bars from Korea for machining and fabrication. For many export buyers, 316L (2.5% Mo) is preferred for corrosion resistance, typically supplied to ASTM A276 Type 316L. We also supply ASTM A276 Type 304L depending on service requirements. Tolerances and surface condition can be aligned to your machining plan and drawing needs. We support MTC (EN 10204 3.1 / 3.2) and packing for export deliveries.

Contact / RFQ

Do you support centerless grinding and special machining requirements?

Yes. Please specify tolerance, surface roughness and any machining/processing requirements so we can confirm availability and lead time.

Can you supply small quantities for prototyping?

Depending on stock availability and sourcing, small quantities can be arranged. Share your required size/grade and destination.

Technical Highlights

	Supply forms: Round, square, flat, ring, hollow, and custom profiles are produced from austenitic, ferritic, duplex, and selected nickel alloys - matched to ASTM / JIS / GB listings and your machining or fabrication route.
	Processing & finish: Hot-rolled and cold-drawn stock, centerless grinding for tight OD, and finishes from No.1 through BA / No.4 / decorative polish - selected to suit corrosion resistance, appearance, or downstream turning requirements.
	Quality & documentation: Chemical and mechanical properties follow standard mill sheets; MTC (e.g. EN 10204 3.1) and PMI or retest can be aligned with your purchase order and project ITP.
	What to send for a quote: Grade, shape, diameter or section size, length, quantity, standard reference, and finish - we confirm availability, tolerance class, and delivery.
