What is ASME SA285 Grade A Pressure Vessel Steel Plate?

ASME SA285 Grade A pressure vessel steel plate is a low-tensile carbon steel specification for fusion-welded boilers and pressure vessels, offering good ductility and basic strength for ambient-temperature services.

As an SA285 Gr A exporter, Gangsteel produces plates that are as-rolled or normalized, ideal for low-pressure environments up to 6 bar and temperatures up to 350°C.

This grade is equivalent to ASTM A 285 Grade A, focusing on weldability without alloy additions, making it economical for non-corrosive applications.

Gangsteel ensures compliance with ASME Section VIII, supplying ASME SA285 Gr A boiler steel for tanks, exchangers, and low-stress vessels.

Compared to ASTM A 285 Grade B, it suits lower-strength setups, with astm a 285 grade equivalent material often being EN P235GH for similar low-pressure uses.

Chemical Composition of ASME SA285 Grade A

The chemical composition of ASME SA285 Grade A prioritizes low carbon for superior weldability and minimal manganese for basic strength, without costly alloys.

In asme sa285 grade a boiler steel chemical composition details, phosphorus and sulfur are tightly controlled to avoid embrittlement.

No silicon or deoxidants are mandated, keeping the formula simple for affordable production.

Frequently Asked Questions (FAQs) About ASME SA285 Grade A Pressure Vessel Steel Plates Supplier

What is ASME SA285 Grade A material?

ASME SA285 Grade A is a low-carbon steel plate for low-pressure vessels, with tensile 45-65 ksi and yield 24 ksi min. It's as-rolled or normalized for ductility and weldability in ambient services.

What is the difference between SA285 Grade A and Grade B?

Grade A has tensile 45-65 ksi and yield 24 ksi, while Grade B (50-70 ksi tensile, 27 ksi yield) suits slightly higher pressures. Both are low-carbon, but Grade A is for lower-strength needs.

What applications suit SA285 Grade A plates?

SA285 Grade A fits low-pressure boilers, storage tanks, and heat exchangers in chemicals and power, handling non-corrosive fluids at moderate temps.

Is SA285 Grade A equivalent to A285 Grade A?

Yes, ASME SA285 Grade A is equivalent to ASTM A285 Grade A, with identical composition (carbon 0.17% max) and properties for ASME code use.

What thickness ranges for SA285 Grade A plates?

Typically 6-50mm, as it's low-strength; Gangsteel offers widths to 3500mm and lengths to 18000mm with custom cuts.
