SA285 Grade C Hot Rolled Pressure Vessel Steel Plate

 

SA285GrC vessel plate is a medium-low strength carbon steel plate for pressure vessels. It complies with ASME A285/A285M or ASTM A285/A285M standards and has good welding performance, toughness and a certain degree of corrosion resistance.

 

SA285GrC boiler plate can still maintain good toughness in low temperature environment, can effectively absorb impact energy, and improve the safety of the structure. It is often used to make fixed boilers, hull boilers and other important boiler accessories and other pressure vessels and structural parts.

 

If you are satisfied with our SA285GrC boiler steel, welcome to place an order with us. As one of the best pressure vessel plate material manufacturers and suppliers in China, we have a large number of hot-selling products for you to choose from.

SA 283 Gr C equivalent material

ASME SA 283 Gr C equivalent material in EN standard is S235JR steel. S235JR steel has good plasticity, toughness and weldability, certain strength and good cold bending properties.

Chemical composition of ASME SA 283 Gr C equivalent material EN S235JR:

Grade	C (t≤16mm)	Si	Mn	P	S	Cu	N
SA 283 Gr C	0.24 max	0.04 max	0.09 max	0.035 max	0.040 max	0.20 min	-
S235JR	0.19 max	-	1.5 max	0.045 max	0.045 max	0.60 max	0.014 max

Mechanical properties of ASME SA 283 Gr C equivalent material EN S235JR:

SA285 gr c vs SA-516-70

The SA 516 Grade 70 is excellent pressure vessel steel plate material to weld and fabricate. For miniature boilers, my preference would be ASME SA 515 Grade 70 because it is more suitable for elevated temperature service. Follow the preheat and post weld heat treatment requirements as defined in ASME B&PV Code, Section I. Both steel plate materials are P-No1 designation.

1. Material Standards & Applications

Property	SA-285 Gr C	SA-516 Gr 70
Standard	ASTM A285 (ASME SA-285)	ASTM A516 (ASME SA-516)
Typical Use	Moderate-temperature pressure vessels, tanks, boilers	Low-temperature pressure vessels, cryogenic storage, welded applications
Service Temperature	Up to 345°C (650°F)	Down to -45°C (-50°F) (with impact testing)

2. Chemical Composition

Element	SA-285 Gr C	SA-516 Gr 70
Carbon (C)	≤0.27%	≤0.27%
Manganese (Mn)	0.90–1.20%	0.85–1.20%
Phosphorus (P)	≤0.035%	≤0.025%
Sulfur (S)	≤0.035%	≤0.025%
Silicon (Si)	≥0.10% (for thickness >12.7 mm)	≥0.15% (killed steel)

 

SA-516 Gr 70 has stricter P/S limits for better weldability and toughness.

SA-516 Gr 70 is typically killed steel (deoxidized), reducing porosity.

3. Mechanical Properties

Property	SA-285 Gr C	SA-516 Gr 70
Tensile Strength	380–515 MPa (55–75 ksi)	485–620 MPa (70–90 ksi)
Yield Strength	≥205 MPa (≥30 ksi)	≥260 MPa (≥38 ksi)
Elongation (A50)	≥23%	≥21%
Impact Testing	Not required	Required (Charpy V-notch at -45°C)

 

SA-516 Gr 70 has higher strength and mandatory impact testing, making it suitable for low-temperature applications.

Although both materials are P1, they are different sub groups. The 516-70 material is G2 and the SA-285-C is G1. The lower the group number, the lower the yield stress. It will depend on what the stress value of your weld rod/wire/consumable is. If you used 65 KSI rod to qualify your 285-C weld procedures and want to use the same procedure for 516-70, you would want to derate your seams to the lower stress value. It is not common practice to use a lower yield consumable than the base metal. Check your weld procedures, your consumable should be 70 KSI or greater to use it on 516-70 or else you are looking at the material stress derate. Or else do your calculations based on the lower stress values of 285-C and use the 516-70 as a higher substitute.
