High‑toughness structural carbon steel plates manufactured to ASME SA573 specification in Grades 58, 65 and 70. Produced by fine‑grain practice to improve fracture toughness, these plates meet the chemical composition limits required by the standard (carbon, manganese, phosphorus, sulfur and silicon) and are supplied with heat and product analysis in accordance with ASME SA573 on request.
Key specification highlights:
- Standards: ASME SA573 (Grades 58, 65, 70)
- Grades available: Grade 58, Grade 65, Grade 70 (improved toughness)
- Typical thickness ranges:
- Grade 58: 1.5 – 100 mm
- Grade 70: limited to maximum thickness of 40 mm (1.5 in)
- Note: coil form available for thicknesses ≤ 25 mm
- Typical plate widths: 1,220 – 4,200 mm
- Typical plate lengths: 5,000 – 18,000 mm
- Dimensional tolerances and flatness: in accordance with ASTM A6
- Forms: plates (and coils where applicable)
Applications:
Suitable for structural and heavy‑fabrication uses where improved toughness is required. Typical uses include welded structures and components subjected to low‑temperature or high‑strain conditions (confirm suitability for specific projects with engineering review).
Quality & services:
Material is produced and tested per ASME SA573 requirements; mill test reports and chemical/mechanical test results can be provided. Fabrication services (cutting, edge preparation, surface treatment) and bespoke dimensions are available subject to supplier capabilities—please request details and lead times when requesting a quote.
