Castings are classified on the basis of the tensile strength of the iron in separately cast test bars. The surface of the casting shall be free of adhering sand, scale, cracks, and hot tears, as determined by visual examination. ASTM A48 / A48M-03(2016), Standard Specification for Gray Iron Castings, ASTM International, West Conshohocken
Grade 30 is the ASTM designation for this material. 200 is the ISO numeric designation. And F12101 is the UNS number. The graph bars on the material properties cards below compare grade 30 cast iron to:cast irons (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. Cast Iron - Class 40 Cast Iron Farmers CopperFarmers Copper Ltd. maintains an extensive inventory of cast iron, class 40, in solid and rectangle bar. Cast iron possesses the highest strength, hardness, resistance to wear and heat treat response for an unalloyed gray iron. It is widely used for bearing and bushing applications in the hydraulics industry.

Classes of Gray Iron - Gray Iron Castings Disa Molding A class 30 gray iron indicates that it has a nominal tensile strength of 30,000 psi. In the International Standard or Sl System a similar iron would be grade 220 with a tensile strength of 220 MPa (megapascals) or 220 newtons per square millimeter. A class designation may be used to indicate a grade of iron even when tensile strength is not an
For example, the number in a Class 30 gray iron refers to the minimum tensile strength in ksi. In ASTM A48,a standard size test bar is added to the class. Class 30A indicates that the iron must have a minimum 30 ksi (207 MPa) tensile strength in an A bar (0.875-in. as-cast diameter). In SAE Standard J431, tensile strength is not required Gray Iron Specifications Tri-CastClass or Grade Min. Tensile psi Other Requirements; ASTM:A48-94:Castings intended for general engineering use where strength is a major consideration. Written exception to this specification takes precedence:20 25 :20,000 25,000:I Test bar size shall be related in cooling rate to the critical section of the casting and so specified.
Sep 20, 2020 · Gray iron Last updated September 20, 2020 Micrograph of grey cast iron.. Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite.  It is the most common cast iron and the most widely used cast material based on weight.
