ASTM A572GR60|A572 Grade 60 steel plate Supplier

Establish the Grade 60 test basis before comparing an offer

ASTM A572 Grade 60 is columbium-vanadium high-strength low-alloy structural steel, not A515 or A516 Grade 60 vessel plate. A complete purchasing requirement includes the A572/A572M edition, A6/A6M basis, unit system, dimensions and intended application. A shared grade number does not establish interchangeable material. Use inch-pound and SI independently rather than mixing rounded limits from the two systems.

The A572/A572M-25 public Scope intends Grades 60 and 65 for riveted or bolted construction of bridges, or riveted, bolted or welded construction in other applications. Retain that application distinction. Notch toughness for applications such as welded bridges must be negotiated; the grade is not an unconditional welded-bridge or impact-performance approval.

SSAB’s datasheet dated 3 December 2025, MetalMate’s Grade 60 guide citing the 25 edition and American Alloy Steel restate these values. They are public mill/compilation references, not an official mechanical-table extract. MetalMate describes no general base-grade tensile maximum. The two elongation values are gauge-dependent and must remain with their specimen basis, not be presented as thickness-band percentages.

Wide-plate elongation has a real public-reference disagreement

For Grade 60 plate wider than 24 in. [600 mm], MetalMate citing A572/A572M-25 restates a three-percentage-point reduction. SSAB’s 3 December 2025 Grade 60 datasheet restates two percentage points, with further A6 adjustments where applicable. Both source statements are reported here; neither is selected as an inspected official clause. Resolve the ordered-edition and specimen provisions before accepting a reduced elongation limit.

Record actual plate width, gauge length and test representation with the report. A certificate percentage detached from that context cannot settle the adjustment. Product-form exceptions also need their own basis; a floor-plate exemption is not a general waiver for ordinary structural plate.

Plate thickness depends on the edition and source being quoted

The official public Scope refers maximum thicknesses to Table 1 but does not publish its numerical contents. Grade 60 public references do not present one consistent size pattern. The following comparison keeps compilation coverage and producer offerings distinct; it is not a substitute for confirming the ordered edition’s actual Table 1.

MetalMate separately gives round bar an exception to 3.5 in. [90 mm], also reflected in Ferrobend note F. That diameter does not expand plate coverage. Neither 2.5 in. nor 1 1/4 in. is claimed here as a paid official table value. Give Gangsteel the actual plate schedule and resolve the applicable edition before accepting a dimension or extending a chemistry band.

Grade 60 carbon is 0.26% maximum in the public reference

The chemistry below is independently printed in MetalMate’s Grade 60 guide citing A572/A572M-25. Basic C/Mn maxima also appear in the Grade 60 distributor columns. This is a public-reference heat-analysis summary, not an official chemistry-table reproduction. Thicker silicon coverage applies only where the ordered edition permits the requested plate size.

MetalMate’s conditional C–Mn allowance permits 0.06 percentage point more manganese for each 0.01 percentage-point carbon reduction below the maximum, to 1.60%. For plate over 3/8 in. [10 mm], minimum Mn is 0.80% heat and 0.75% product; thinner plate and other products use 0.50% heat and 0.45% product. Heat Mn/C is at least 2:1. These product minima are explicitly printed in the Grade 60 guide; they do not create a full product-analysis grid for other elements.

The guide permits 0.04% P and 0.05% S for shapes, sheet piling, bars and plate no more than 15 in. [380 mm] wide. Those are product-form/width exceptions, not universal plate limits. Undated distributor grids with the higher figures do not remove that qualification. Copper is conditional and does not convert the material into A588; the official Scope requires agreement before an A588 substitution.

Identify the type and documentary acceptance conditions

The public Scope requires Nb/columbium, V, Ti, N or combinations under Type 1, 2, 3 or 5, normally at producer option unless specified under S90. The following numeric type references come only from MetalMate Grade 60, not an independently confirmed official table:

• Type 1: Nb 0.005–0.05%.
• Type 2: V 0.01–0.15%.
• Type 3: Nb 0.005–0.05%, V 0.01–0.15%, with Nb+V 0.02–0.15%.
• Type 5: Ti 0.006–0.04%, N 0.003–0.015%, V 0.06% maximum.

Confirm required delivered condition, analysis scope, tests and certificate form with the quotation. Impact acceptance needs its own conditions and values, not a default energy or test direction. Welding and subsequent treatment require suitable project procedures. No stock, lead time, certificate approval or automatic national-grade equivalence is promised.

Grade 60 acceptance and enquiry questions

Which elongation pair should a Grade 60 inspection plan start with?

The public references give 16% in 8 in. [200 mm] and 18% in 2 in. [50 mm], before the applicable specimen and adjustment provisions are assessed. Keep the gauge with the percentage. Do not treat them as separate thin-plate and thick-plate limits.

Can the wide-plate reduction be chosen from whichever source is convenient?

No. MetalMate’s -25 restatement gives three percentage points for Grade 60, while SSAB’s December 2025 datasheet gives two. Confirm the exact ordered-edition provisions and specimen basis rather than select one as the official rule. The reported disagreement is not a discretionary acceptance option.

Does the 2025 shape-flange note prove a 2.5 in. plate cap?

No. That change note explicitly concerns shapes. MetalMate separately restates 2.5 in. [64 mm] plate/bar coverage, while undated distributor tables show 1 1/4 in. [32 mm] plate. Confirm the ordered Table 1; a producer offering or shape note alone does not establish its official plate value.

May a copper-bearing requirement be assumed for every Grade 60 heat?

No. The public reference applies copper minima only when specified. State the copper option on the enquiry if required, then retain the analysis basis and actual material identity in the records. It is not an automatic weathering-steel or corrosion-performance designation.

Is A572 Grade 60 interchangeable with vessel Grade 60 or A572 Grade 65?

Not from a shared number or family name. Vessel specifications have different purposes and requirements, and Grade 65 is another strength grade. A proposed alternative needs the required technical review and purchasing approval. Related product pages do not themselves authorize substitution.
