Steel Grade Equivalence Guide
Use this page to prepare an RFQ for buyers comparing ASTM, EN, JIS, GB, and API steel grades before sending an RFQ. It keeps the inquiry focused on grade, size, quantity, tolerance, certificate, packing, and destination details.
How To Specify This Requirement
Steel Grade Equivalence Guide RFQs should confirm the application, standard, grade, product form, size range, delivery condition, and inspection scope.
Himount Steel reviews the ordered standard, grade, dimensions, inspection level, packing method, and shipment route before confirming price and lead time.

International Standard Notes
This page uses the buyer-facing reference `Buyer project standard` and grade/code `Original standard and grade must be confirmed before any equivalent is accepted` as RFQ checkpoints. The table below helps compare common international wording without claiming automatic equivalence.
| ASTM reference | ASTM A36, A572, A588, and A240 may appear in plate RFQs depending on structural, weathering, or stainless requirements. |
|---|---|
| EN / JIS / GB reference | EN 10025, JIS G3101, GB/T 700, and GB/T 1591 may appear in regional project documents and should be quoted from the buyer specification. |
