WH80Q Steel Plate for Sale | RFQ Supply
WH80Q plate for sale / RFQ supply page. Gangsteel quotes stock and mill production, cut-to-size, and export packing with full heat traceability.
This page is a standalone technical article. For the primary overview on the original URL, see WH80Q Steel Plate Specifications.
Standards and Ordering Context
Order WH80Q by writing the full standard designation used on the contract (for example ASTM/ASME, EN, GB/T, JIS, or a class society grade string). Ambiguous short names create certificate mismatches at receiving inspection. When dual marking is required, list every standard on the purchase order before the mill books the heat.
Chemical Composition (Planning Table)
Values below are RFQ-oriented. Acceptance is always against the ordered specification edition and the mill heat analysis.
| Element / item | WH80Q (planning values) | Note |
|---|
| C, Mn, Si, P, S | Per ordered specification edition | Use MTC heat analysis for acceptance |
| Cr / Ni / Mo / V / Nb / Ti | As required by grade family | Stainless / alloy / microalloy as applicable |
| Residuals | Per spec max | Cu, B, N when controlled |
| Carbon equivalent | State if welding critical | IIW or JIS formula as specified |
Mechanical Properties (Confirm on MTC)
| Property | Typical requirement to confirm on MTC | Comment |
|---|
| Yield strength | Per grade / thickness table | Do not design from marketing pages |
| Tensile strength | Min–max or min per spec | |
| Elongation | Thickness-dependent | |
| Impact / hardness | When grade requires | Temperature & orientation on PO |
| Delivery condition | AR / N / NR / QT / TMCP / annealed | Match mill route to approval |
Applications
| Sector | Use note |
|---|
| Pressure equipment | WH80Q when listed on calculation / material summary |
| Structural / OEM | Fabricated frames, bases, wear or load members as specified |
| Ship / offshore | Only with matching class grade & stamp |
| Process industry | Vessels, exchangers, skids — verify corrosion allowance |
Comparison and Substitution Notes
| Check before substitute | Why |
|---|
| Exact standard + grade string | Names alone (e.g. “36”) collide across families |
| Strength vs toughness letter | Ship grades: numeral ≠ letter meaning |
| Product form | Plate vs forging vs pipe have different specs |
| Certificate society / code | BV ≠ KR stamp; ASME ≠ EN without dual mark |
Related grades that only share a letter or number token are frequent collision sources in catalogs. Keep strength tier, toughness temperature, corrosion class, and product form explicit in internal links and BOMs.
Fabrication and Quality Notes
Weld WH80Q only to approved procedures for thickness and carbon equivalent. Preserve heat numbers on every cut piece. Add UT, Z-quality, PMI, or third-party witness when the project specification requires them. This article is not a WPS or design calculation.

Frequently Asked Questions
Can Gangsteel supply WH80Q plate from stock or mill production?
Yes. Gangsteel quotes stock plates when available and mill production for project tonnages. Export packing, cut-to-size, and third-party inspection can be included when specified on the RFQ. Primary overview: WH80Q Steel Plate Specifications.
What details make a WH80Q supply quote faster?
Size list or nesting, tonnage, destination port, required certificate marks, inspection clause, and finish. Alloy grades should note any dual-mark or class stamp needs up front.
Do cut pieces keep heat traceability?
Yes—cut pieces should retain heat identity via stencil, stamp, or tagged maps tied to the MTC. Send nesting files early if remnant planning matters for sister units.
How are packing and lead time handled?
Seaworthy packing is standard for export stainless and alloy plate; edge guards and moisture protection are added as needed. Stock can move after commercial clearance; mill leads depend on thickness and order mass.
What certificate does Gangsteel supply for WH80Q?
EN 10204 3.1 is standard. EN 10204 3.2 is available when a purchaser-appointed inspector witnesses testing. Class stamps (BV, KR, LR, ABS, DNV, CCS, NK, RINA, etc.) are arranged when the purchase order and mill approval require them. The MTC lists heat analysis, mechanical tests, heat-treatment / delivery condition, and heat number traceability.
How do I RFQ WH80Q from Gangsteel?
Send the exact standard and grade, thickness × width × length (or nesting list), quantity or tonnage, delivery condition, required tests (impact, UT, Z-quality, PMI), certificate type, destination, and any dual-mark needs. Gangsteel replies with mill options, lead time, and packing notes.
Ordering and Mill Certificates
State grade WH80Q, dimensions, quantity, delivery condition, optional NDT/PMI, and certificate (EN 10204 3.1 standard; 3.2 when third-party inspection is ordered). Gangsteel supplies export plate and related products with mill test certificates. Contact Gangsteel for stock and mill production RFQs.
