What is ASTM A395?
ASTM A395 is a Specification for Ferritic Ductile Iron Pressure-Retaining Castings for Use at Elevated Temperatures.Category
Wrought Iron, Cast Iron, and Malleable IronScope
This specification covers ductile iron castings for pressure-retaining parts for use at elevated temperatures. Castings of all grades are suitable for use up to 450°F. For temperatures above 450°F and up to 650°F, only Grade 60−40−18 castings are suitable.Ok let's start with ASTM A395 chemical composition.

Now it's the mechanical properties turn:
Yield Strength
Grade 60-40-18
40 ksi (275 MPa) min.Learn more about what is yield strength.
Tensile Strength
Grade 60-40-18
60 ksi (415 MPa) min.Learn more about what is tensile strength.
Elongation (min.) 50 mm
0.18.Learn more about what is elongation.
Reduction of Area (min. %)
Not Required.Learn more about reduction of area.
Hardness Requirements
Grade 60-40-18
143 - 187 HBLearn more about what is hardness.
Allowable Stress
Depends on the project (And its factor of safety).Learn more about the what is allowable stress.
My Material's Rank
While engineers will often look for the cheapest material they can use, I took a different approach to material's selection to help newbie students.I ranked materials according to their yield strengths and ASTM A395 currently ranks 73 in my yield strength index. This means there are other 72 materials that are more resistant.
Note: I've analysed 134 materials in order to create an yield strength index. Check my astm material's comparison post for more details.

Citation
When you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.That gives credibility to your paper and it is sometimes required in higher education.
To make your life (and citation) easier just copy & paste the information below into your assignment or essay:
Luz, Gelson. ASTM A395 Properties (Chem., Mech. & Rankings). Materials Blog. Gelsonluz.com. dd mmmm. yyyy. <URL>
Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
