In the competitive market for pressure vessel steels, pricing for ASTM A537 plates can fluctuate based on class, thickness, quantity, and global supply dynamics.
At Gangsteel, we specialize in producing and exporting high-quality options under the ASTM A537/A537M specification, which includes Classes 1, 2, and 3 for heat-treated carbon-manganese-silicon steels used in boilers and vessels.
As of September 29, 2025, prices reflect stable post-recovery trends, influenced by raw material costs and demand from energy sectors.
Gangsteel offers competitive rates for ASTM A 537 Class 1, ASTM A 537 Class 2, and ASTM A 537 Class 3.
This guide from Gangsteel breaks down current pricing, factors, and comparisons to help with procurement.
ASTM A537 covers normalized or quenched and tempered plates for welded pressure vessels.
Class 1 is normalized for moderate strength, ideal for general boilers.
Class 2 and 3 are quenched and tempered for higher yields in demanding services.
Prices vary by class due to heat treatment complexity.
Gangsteel aligns with ASME SA537/SA537M equivalents like ASME SA 537 Class 1 for code-compliant projects.
The composition supports pricing through material efficiency.
Carbon max 0.24%, manganese 0.70-1.60% (thickness-dependent), with low P/S at 0.035% max.
Silicon 0.15-0.50% aids deoxidation.
Optional alloys like Cu/Ni add 5-10% to costs for corrosion resistance.
This uniformity across classes keeps base prices consistent.

Higher strength in Classes 2/3 justifies premiums.
Class 1: Yield 50 ksi min (≤65mm), tensile 70-90 ksi.
Class 2: Yield 60 ksi min, tensile 80-100 ksi.
Class 3: Yield 55 ksi min, tensile 75-95 ksi.
Quenched/tempered classes cost more due to processing.

Density is 7.85 g/cm³ across classes, aiding weight-based pricing.
Delivered normalized (Class 1) or quenched/tempered (Classes 2/3), with MTCs.
Gangsteel offers testing add-ons at extra cost.
Thicknesses: 6-300mm (Class 1), 5-150mm (Classes 2/3).
Widths to 3500mm, lengths to 18000mm.
Custom cuts add 10-15% to base price.
As of September 29, 2025, prices range $600-3,000 per metric ton globally.
Class 1 averages $800-1,200/ton for 20-50mm thick standard plates.
Classes 2/3: $1,000-2,500/ton due to heat treatment.
Asia: $680-1,000/ton; Europe/North America: $1,500-2,800/ton.
Bulk (100+ tons) discounts 5-10%.
Gangsteel starts at $800/ton for Class 1, $1,200 for Class 2.
Example: 100 tons Class 1 (25mm) ~$950/ton FOB.

Raw materials (iron ore, alloys) drive 60% of costs.
Energy for heat treatment adds $200-500/ton for Classes 2/3.
Quantity: Bulk lowers per-ton rate.
Thickness: Thicker >$1,500/ton.
Certifications (HIC, impact): +10-20%.
Global trends: 5-10% YoY rise from demand.
Direct: ASME SA537/SA537M.
Class 1: EN P355GH, JIS SPV355.
Class 2: EN P460NH, JIS SPV490.
These have similar pricing, ±10% regionally.

ASTM A537 suits high-pressure boilers, sour tanks.
Higher classes enable cost savings via thinner plates.
Gangsteel advises for project-specific quotes.
As of September 29, 2025, ASTM A537 plates range $600-3,000 per metric ton, with Class 1 at $800-1,200/ton standard, Classes 2/3 at $1,000-2,500/ton. Prices vary by region, thickness, and quantity; Gangsteel offers from $800/ton for bulk Class 1.
Key factors include class (higher for 2/3 due to heat treatment), thickness (thicker adds 20-30%), quantity (bulk discounts 5-10%), region (Asia lower than Europe/NA), and add-ons like HIC testing (+10%). Raw material fluctuations and energy costs also impact, with 5-10% YoY increases expected.
Class 1 averages $800-1,200 per ton for 20-50mm thick plates in standard conditions. In Asia, $680-1,000; Europe/NA, $1,500-2,000. Bulk orders reduce to $750/ton; thicker or certified adds $200-500.
Class 2, with quenching/tempering, ranges $1,000-2,500 per ton. Standard: $1,200-1,800; premium HIC-tested: up to $2,500. Regional: Asia $900-1,500, Europe/NA $1,800-2,800. Gangsteel quotes from $1,200/ton bulk.
A537 is 20-50% pricier than A516 Gr70 ($500-1,000/ton) due to heat treatment and higher strength. A537 suits demanding apps; A516 for general use.
In summary, ASTM A537 pricing balances quality with value. Contact Gangsteel for tailored quotes.
