Unlike white cast iron, gray iron has a graphitic microstructure. It has excellent vibration damping capacity and great machinability. White and gray cast irons create very similar looking castings. Their coloring is only evident when they fracture. Ductile iron is a good choice for an item that might deal with the impact force of a vehicle.See all results for this questionWhat are the tensile strengths of grey cast iron?Gray cast irons have low tensile strengths and almost nonexistent ductilities (and impact strengths) due primarily to the nearly continuous nature (breaks at cell boundaries and at prior austenite dendrites) of the graphite flakes (see Fig. 3). Tensile stresses propagate cracks along the graphite plates internally.See all results for this questionWhat are the grades for gray iron casting?This is a comparison table for some gray iron casting grades in these standards: Specifications Grade Tensile Strength (PSI) Hardness (BHN) ASTM A48 Class 25 25,000 170-229 SAE J431 G2500 25,000 170-229 GM274M G150 21,750 143-207 ASTM A48 Class 30 30,000 187-241 8 more rows comparison table for some gray iron casting grades PaintingSee all results for this question

Cast Iron Standards. ASTM's ferroalloy and casting standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of iron alloys and their castings. The iron castings can be of the ferritic, austenitic, gray, cupola, pearlitic, ductile, or malleable types.See all results for this questionThe Differences Between Ductile Iron and Gray Iron CastingsJun 18, 2015 · Jun 18, 2015 · There are many grades of gray iron as per the ASTM A48 standard. While gray iron does not have a measurable yield strength, the range for tensile strength is 20,000 psi 60,000 psi. Impact Ductile iron has a greater resistance to impacts, and is able to resist a minimum of 7 foot pounds of impact (versus 2 pounds of impact for gray iron).Paint Standards and Related Coating StandardsPaint Standards and Related Coating Standards. ASTM's paint and related coating standards are instrumental in specifying and evaluating the physical and chemical properties of various paints and coatings that are applied to certain bulk materials to improve their surface properties.

Grey cast iron, or grey iron, has graphitic flakes which deflect a passing crack and initiate countless new cracks as the material breaks. Carbon (C) and silicon (Si) are the main alloying elements, with the amount ranging from 2.5 to 4 wt% and 1 to 3 wt%, respectively.Gray Iron Iron Casting Research Institute, Inc.Sep 07, 1990 · Sep 07, 1990 · The range of compositions which one may find in gray iron castings is as follows: total carbon, 2.75 to 4.00 percent; silicon, 0.75 to 3.00 percent; manganese, 0.25 to 1.50 percent; sulfur, 0.02 to 0.20 percent; phosphorus, 0.02 to 0.75 percent.Flexible Iron? Ductile Iron vs. Cast Iron | Castings BlogBeing ductile allows the iron to bend. In comparison, gray cast iron is harder. This hardness means that it manages surface wear well. Gray iron is also better at vibration damping. The differences are due to the microstructures of graphite within these iron alloys. Gray cast iron is 2.54% carbon and 13% silicon by weight.

When it comes to corrosion, iron has better corrosion resistance than steel. That doesn't mean that either is impervious to corrosion though. When left unprotected, both metals will oxidize in the presence of moisture. Eventually, they will completely decompose. To prevent this, the coating is recommended for both steel and iron castings.See more on wermac.orgDie Casting Aluminum Selection Guideavailable aluminum die casting alloys, but the entire group is superior to iron, steel and titanium. The rapid solidication rate associated with the die casting process makes die casting alloys somewhat superior to wrought and gravity cast alloys of similar chemical composition. Alloy A380 has better than average machining characteristics.Damping Properties of Selected Steels and Cast Ironsprohibitive. Some aluminum alloys and brass have SDC's on the order of 0.01 to 1 pct at stress levels below 3,500 psi.

13 rows · Comparison Table for Some Gray Iron Casting Grades. ASTM A48, SAE J431, GM 274M and ASTM A126 are standards for gray cast iron. They have some grades which have some equal or similar mechanical properties, such as tensile strength and hardness. Gray iron castings have good casting properties, vibration damping, wear resistance, machinability and low notch sensitivity.ASTM A48Class 2525,000170-229SAE J431G250025,000170-229GM274MG15021,750143-207ASTM A48Class 3030,000187-241See all 13 rows on www.iron-foundry comparison table for some gray iron casting grades PaintingChilled Cast Iron - an overview | ScienceDirect Topics5.3.1 Chilled cast iron.

Grey iron is the cheapest and the easiest to cast to get sound castings. Compacted graphite irons have superior mechanical properties, even at elevated temperatures than grey iron, but are expensive and are not typically heat-treated.

There are two major types of iron produced: wrought iron and cast iron. Within those, cast iron includes its own family of metals.See more on reliance-foundry comparison table for some gray iron casting grades PaintingEstimated Reading Time: 10 minsCast Iron Standards - ASTM InternationalA126 - 04 (2019) Standard Specification for Gray Iron Castings for Valves, Flanges, and Pipe Fittings.
