Pressure-vessel plate with the delivery condition and test scope on each material line
Our A516 Grade 70 plate program lists 3/16–6 in. thickness, 48–120 in. width and 96–480 in. length. We quote full plates or cut blanks for vessel fabricators, with the actual dimensional combination, delivery condition, ASTM or ASME material callout and required tests stated together.
| Material callout | ASTM A516 Grade 70; expressly ordered ASME SA-516 or dual certification identified in the supplied records |
|---|---|
| Published dimensional envelope | Thickness 3/16–6 in.; width 48–120 in.; length 96–480 in. Actual combination returned with the plate offer. |
| Delivery condition | As-rolled or the specified normalized/thermal condition |
| Cut pieces | Finished dimensions, edge preparation and retained heat identity |
| Supplementary tests | Impact, ultrasonic or simulated PWHT requirements listed individually |
| Records | Mill material record and the tests applicable to the supplied plate |
These reference values identify the Grade 70 material level. The actual mill record states the plate condition and results for the supplied thickness and governing specification.
| Property | US reference value | SI reference value | Scope |
|---|---|---|---|
| Minimum yield strength | 38 ksi | 260 MPa | Grade 70 plate |
| Tensile strength | 70–90 ksi | 485–620 MPa | Grade 70 plate |
| Minimum elongation, 2 in. gauge length | 21% | 21% | Specified specimen basis |
| Minimum elongation, 8 in. gauge length | 17% | 17% | Specified specimen basis |

Grade 70 reference properties cross-checked against SSAB primary material data and ASTM A516/A516M requirements. ASTM SI and inch-pound values retain their specified bases; applicable specimen and thickness adjustments govern elongation. The supplied heat-specific material report records the delivered plate results.
The material purchase line identifies ASTM A516, ASME SA-516 or the required dual certification. Our offer and supplied records carry the accepted designation and delivery condition together.
A Charpy requirement identifies temperature, orientation, specimen size and acceptance criteria. Those details define the impact-test scope for the ordered Grade 70 plate.
The plate order covers its material specification and required records. Vessel construction rules separately govern allowable stress, fabrication, examinations and any vessel code stamp.
The receiving description identifies normalized material where ordered. A later forming or heat-treatment route can change the relevant material condition, so the fabrication plan and required records stay aligned.
A head or shell blank retains its finished size, required edge preparation and parent-plate rolling direction where called for. The cutting map links each delivered shape and its identification to the material heat.
Where required, the material-test scope includes the specified simulated thermal cycle and accumulated time. The report identifies the test condition so the fabricator can compare the result with the approved vessel fabrication cycle.
Full plates and blanks are separated by delivery condition and material callout. Shell and head items keep the dimensions and later processing assumptions used by the fabricator.
A replacement plate follows the approved repair specification. Grade, delivery condition and required examinations are matched to that repair line before the material is quoted.
Plate markings and cut-piece records are checked against the material document. The heat, product dimensions and delivery condition connect the supplied pieces to their material results.
Thickness, width, length and the agreed edge/surface condition follow the plate acceptance requirements. Local grinding or repair, where allowed, retains the applicable material and inspection basis.
Tensile, impact and supplementary examination records identify the tested condition and the plate or test unit covered. A simulated-PWHT requirement also carries its thermal-cycle basis, so the fabricator can match the received material to the approved test scope.
Our offer distinguishes full plates, finished blanks, heat-treatment condition and supplementary testing. Cutting, edge preparation and required records remain identifiable in the price basis.
Plates and blanks are supported on aligned dunnage with restraints selected for the shipment. Prepared edges and identification locations remain accessible for the receiving check.
The cutting list separates delivered blanks from unused plate. Piece quantities, finished dimensions and the agreed net-blank or parent-plate price basis show how material yield enters the offer.
The quotation and material records identify normalized delivery explicitly. Grade and delivery condition are separate order details, with permitted conditions governed by the specification and plate thickness.
The vessel or repair specification governs material acceptance. A proposed replacement is checked for the required strength, material quality, delivery condition and tests, alongside thickness and finished dimensions.
Elongation is measured over a stated gauge length. The 21% and 17% reference values use different specimen bases; acceptance compares each result with its corresponding gauge length and applicable thickness adjustment.
Yes. The cutting and marking arrangement links each delivered piece to its parent plate and heat. The record package and permitted marking method are agreed before cutting, including any restrictions on hard stamping.
The exact ordered inch thickness stays on the material line with its tolerance basis. Any proposed metric size is identified separately and used when the purchase specification accepts the resulting dimensions and tolerances.
Plate supply, cut blanks, edge preparation and formed heads are different scopes. Our plate offer identifies the material and processing included; a head-forming requirement needs its own drawing, process and acceptance basis.
