In the competitive landscape of pressure vessel and boiler manufacturing, finding a reliable supplier for cost-effective carbon steel plates is vital for low-pressure applications in industries such as oil refining, chemical processing, and power generation.
As a leading producer and exporter, Gangsteel is your trusted ASTM ASME SA285 Grade B supplier, offering SA285 Grade B carbon steel plates that comply with the ASME SA 285/SA 285M specification for fusion-welded vessels. This low-carbon material provides moderate strength and excellent weldability, making it suitable for ambient-temperature services.
Whether you're building storage tanks or heat exchangers, Gangsteel ensures high-quality ASME SA285 Gr B boiler steel with global delivery. For comparisons, explore our ASME SA 285 Grade A for lower tensile or ASME SA 285 Grade C for higher strength requirements.
ASME SA285 Grade B (SA285GR.B) carbon steel plates are a low- to intermediate-tensile strength material specified for fusion-welded pressure vessels and boilers, offering good ductility for forming and moderate resistance to stress.
As a dedicated SA285 Gr B exporter, Gangsteel manufactures plates that are as-rolled or normalized, ideal for low-pressure environments up to 8 bar and temperatures up to 400°C.
This grade is equivalent to ASTM A 285 Grade B, emphasizing weldability without alloys, making it economical for non-corrosive services.
Gangsteel supplies ASME SA285 Gr B boiler steel for applications like storage tanks, low-pressure boilers, and simple reactors, ensuring adherence to ASME Section VIII for diverse markets.
Compared to ASTM A 285 Grade A, it provides higher strength for slightly elevated pressures, with astm a285 grade equivalent material often being EN P265GH for similar low-pressure uses.
The chemical composition of ASME SA285 Grade B prioritizes low carbon for excellent weldability and moderate manganese for strength enhancement without added costs.
In asme sa285 grade b boiler steel chemical composition details, phosphorus and sulfur are minimized to reduce the risk of embrittlement during welding or service.
No silicon or other deoxidants are required, keeping the formula straightforward and production affordable.

No impact testing is mandatory, but Gangsteel offers optional Charpy for enhanced assurance. Density is 7.85 g/cm³, standard for carbon steels.
As noted in sa285 gr b mechanical properties and density guide, density is 7.85 g/cm³ (7850 kg/m³), facilitating precise engineering calculations.
Plates are delivered as-rolled, with Gangsteel providing normalization or stress relieving for reduced welding stresses.
We include ultrasonic testing for quality, ensuring defect-free plates ready for fabrication.
Gangsteel supplies ASME SA285 Grade B in thicknesses from 6mm to 50mm (limited for intermediate-strength grade), widths up to 3500mm, and lengths to 18000mm.
Compliant with ASTM A285/A285M, we offer custom beveling and cuts.
For varying strengths, compare with ASME SA 285 Grade A or C.

SA285 Grade B is applied in low- to moderate-pressure tanks, boilers, and exchangers, offering easy welding without preheating.
In India, it's popular for refinery vessels due to moderate cost.
Advantages include affordability over higher-strength steels and good ductility in mild conditions.
ASME SA285 Grade B is a low- to intermediate-carbon steel plate for pressure vessels, with tensile 50-70 ksi and yield 27 ksi min. It's as-rolled or normalized for ductility and weldability in ambient services.
Grade B has tensile 50-70 ksi and yield 27 ksi, while Grade A (45-65 ksi tensile, 24 ksi yield) is for lower pressures. Both are low-carbon, but Grade B suits slightly higher loads.
SA285 Grade B fits low- to moderate-pressure boilers, storage tanks, and heat exchangers in chemicals and power, handling non-corrosive fluids at moderate temps.
Yes, ASME SA285 Grade B is equivalent to ASTM A285 Grade B, with identical composition (carbon 0.22% max) and properties for ASME code use.
Typically 6-50mm, as it's intermediate-strength; Gangsteel offers widths to 3500mm and lengths to 18000mm with custom cuts.
No standard requirement, but optional Charpy for low-temp; suitable for ambient without it.
Not recommended without testing, as it's basic carbon steel; for sour, choose HIC-tested or higher grades like A516.
In summary, ASME SA285 Grade B (SA285GR.B) carbon steel plates from Gangsteel are a versatile, affordable choice for moderate-pressure vessels, with reliable supply and customization. Contact us for quotes on ASME SA 285 Grade B.
