ASTM A387 grade 5 class 2 steel sheet technical data

Posted:2020-11-25 10:57:12

ASTM A387 grade 5 class 2 steel sheet is chromium-molybdenum alloy steel. It is intended primarily for welded boilers and pressure vessels which are designed for use in raised temperature service. With excellent heat resistance and anti corrosive properties, A387 grade 5 class 2 steel sheet is ideal for use in the chemical, oil and gas industry.

ASTM A387 grade 5 class 2 steel sheet chemical composition:

Grade	UNS	C	Mn	P	S	Si	Cr	Mo	Others
A387 grade 5 class 2	S50200	≤0.15	0.25-0.66	0.025	0.025	≤0.55	3.90-6.10	0.40-0.70	-

ASTM A387 grade 5 class 2 steel sheet mechanical properties:

Grade	Tensile Strength	Yield Strength	Elongation in 2 inches
	(Mpa) min.	(MPa) min.	(%) max.
A387 grade 5 class 2	515-690	310	18

ASTM A387 grade 5 class 2 steel sheet has high tensile strength levels and resistance from crevice corrosion, plate cracking corrosion at high temperatures. A387 grade 5 class 2 steel sheet can also withstand the corrosion of rust and seawater.
