Product Introduction

A high quality ASTM A387 Grade 5 Class2 steel or chrome molybdenum alloy steel plate intended specifically for use in weldable carbon steel pressure vessels at elevated temperatures. Added molybdenum gives the material greater temperature tensile strength and the chromium provides improved corrosion resistance.

Chromium & Molybdenum content (according to the ASTM specification):

Designation	Nominal Chromium Content (%)	Nominal Molybdenum Content (%)
A387 Grade 5	5.00%	0.50%

Chemical Composition of ASTM A387 Grade 5 Class 2 Steel:

Grade	C	Si	Mn	P	S	Cr	Mo
A387 GR.5 CL.2	0.15 max	0.55 max	0.25-0.66 max	0.035 max	0.035 max	3.90-6.10 max	0.40-0.70 max

Mechanical properties of ASTM A387 Grade 5 Class 2 Steel:

Requirement:	Grade 5
Tensile strength, ksi [MPA]	75 to 100 [515 to 690]
Yield strength, min, ksi [MPa]/(0.2% offset)	45 [310]
Elongation in 8 in. [200mm], min %	...
Elongation in 2 in. [50mm], min, %	18
