What is SA 285 Grade C Plate
SA 285 Grade C plate is a carbon steel plate designed for pressure vessels and boilers operating at low to moderate temperatures. ASTM A285 and ASME SA285 cover the same specification, so buyers sourcing under either standard receive an identical material. The grade carries a carbon content capped at 0.16%, manganese between 0.4% and 1.2%, and residual limits of 0.03% each for phosphorus and sulfur figures that keep the plate weldable without heat-treatment complications.
Rexton Steel & Alloys has supplied SA 285 GR. C plate has been shipped domestically and internationally through FOB shipments for more than 30 years. Rexton Steel & Alloys routinely ships SA 285 GR. C plates are available in a width range of 1000 mm to 4500 mm, thickness from 5 mm to 150 mm, and a length of 18,000 mm, as-rolled and cut according to the customer’s drawing.

Key Features and Benefits of SA 285 GR C
The mechanical properties include a yield strength of 205 MPa, a tensile strength between 380 to 515 MPa, and a minimum elongation of 27% in a length of 50 mm. These low-to-intermediate strength values are suitable for pressure equipment operating well below the limits of higher-grade plates like SA 516 Gr. 70. Good weldability results from the restrained carbon and sulfur content. The plate resists general corrosion, pitting, and stress-corrosion cracking in typical boiler and tank environments, and it holds dimensional accuracy through cutting, forming, and drilling.
Equivalent designations exist across standards: BS 1501-161 Gr.360/164 Gr.360, EN 10028 P235GH, JIS SPV24, and Spain's UNE A37 RCI. Buyers matching a European Norm spec to an ASTM order can cross-reference these grades directly.
Manufacturing Process
Rolling starts with raw material that is tested for composition before entering production. Plates then progress through cutting, machining, drilling, forming, and grinding. Heat treatment can include as-rolled, controlled rolling, or normalizing, which is determined by the thickness of the plate and the end use. Quality control is performed for each step. Therefore, composition and dimensions are verified at each processing stage instead of just at a final inspection. This prevents deviations from reaching the buyer.

Testing and Inspection
Every batch is tested for tensile strength, elongation, and reduction of area, as well as spectrochemical analysis, impact testing, hydrostatic testing, positive material identification, X-ray testing, and hardness testing. Buyers receive mill test certificates issued to EN 10204 3.1B, plus buyer test reports, lab test reports, and third-party inspection reports on request documentation that confirms the plate matches its ordered specification before it leaves the facility.
Packaging and Documentation
Each plate gets packed to standard or custom specifications built around the shipping route and cargo type, cutting down transit damage on sea and inland freight alike. Shipments include a fumigation certificate, heat treatment chart, raw material test report, quality assurance plan, material traceability report, commercial invoice, packing list, and guarantee letter, giving buyers full traceability from mill to site.
Applications of ASTM A285 Grade C Plate
SA 285 Gr C plate goes into boiler shells, storage tanks, and pressure vessels operating at moderate pressure, along with structural fabrication in bridges, shipbuilding, and offshore platforms. Petrochemical plants use it for low-pressure vessel components, and general engineering projects specify it wherever a low-to-intermediate strength carbon steel meets the load requirements.
