The Workhorse Materials, Cut to Spec: Korean A36, Stainless 304 316, and Special Steels — Small Quantities, Delivered to Your Dock

Most parts aren't made from exotic alloys. They're made from the everyday workhorses — general carbon steel, stainless, and the alloy and tool steels every machine shop runs through every week. The problem isn't knowing what you need. The problem is getting it in the quantity you actually want, in the grade your drawing calls out, without a mill minimum or a six-week wait.

For stainless and special steels, it's even harder. Try sourcing a few bars of a specific tool-steel grade, or a small lot of certified alloy steel, in a hurry. The domestic catalog runs thin fast.

That's exactly the gap Belinker fills — and with the materials below, it's where we're strongest.

What we supply

Belinker sources Korea's most-used engineering materials and delivers them cut to your size, in the quantity you need, matched to U.S. specifications, and certified. Carbon steel, stainless, alloy steel, tool steel — and because we run our own CNC machining and fabrication, we can finish-machine the part instead of just shipping raw stock.

The materials — and their U.S. equivalents

Korean (KS/JIS) grades map cleanly onto the ASTM and AISI standards your engineers already specify. We supply against your spec and certify the match.

General carbon steel / 일반 탄소강

Stainless steel (SUS) / 스테인리스강

Special & tool steel

(Aluminum on request: A6061→6061, A5052→5052, A7075→7075.)

Don't see your grade? Send the spec — if it's used in Korean manufacturing, we can source and certify it.

Why buyers work with us

Backed by SeAH Group. Belinker is backed by SeAH Group — one of Korea's largest specialty- and stainless-steel groups. That gives us deep roots in exactly the alloy, stainless, and tool steels on this page, and the credibility behind every certificate we issue.

No MOQ. A few bars, a single plate, a small lot — order the quantity your job actually requires, not the mill's minimum.

Matched to U.S. spec, certified. Every order ships with a Mill Test Report (MTR) and grade certification against the ASTM/AISI equivalent. Your inspector sees documentation, not a translation problem.

Cut and machined — not just supplied. Cut-to-length is standard. Because Belinker runs CNC machining and fabrication in-house, we can deliver finished, ready-to-install parts. Send a drawing; get the part.

One landed price, handled end to end. Belinker America Inc. (Illinois) manages export, U.S. customs clearance, and import duties. You get a single delivered price to your dock and a U.S.-based point of contact — no import paperwork, no customs broker, no tariff admin on your side. Duties are included in your quote, so there are no surprises after the order ships.

Who this is for

• Machine shops that need a specific bar grade now, not a full bundle next month

• OEMs and equipment builders sourcing small, certified lots of carbon, stainless, or alloy steel

• Tool & die makers chasing D2, H13, or a specific tool-steel grade in small quantities

• R&D and prototyping teams that need the right material in the right amount, fast

• MRO and maintenance buyers sourcing a hard-to-find stainless or special steel

If the mill's minimums and the service center's catalog don't fit your project, we do.
