With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
This deviation, usually 0.2 %, is included in the definition of yield strength or proof stress in international specifications (see Section XII) and is often incorporated in the yield strength terminology, e.g. "0.2 % yield strength". Yield strengths for Ductile Iron typically range from 40,000 psi (275 MPa) for ferritic grades to over 90,000 psi (620 MPa) for martensitic grades.

Material Notes: This property data is a summary of similar materials in the MatWeb database for the category "Cast Iron". Each property range of values reported is minimum and maximum values of appropriate MatWeb entries.
Grey cast iron is a cast iron. It has the highest thermal conductivity among the cast irons in the database. The properties of grey cast iron include eleven common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below.
Iron metal is greyish in appearance, and is very ductile and malleable. It begins to rust in damp air and at elevated temperatures, but not in dry air. It dissolves readily in dilute acids, and is chemically active. The main mining areas for iron are China, Australia, Brazil, Russia, and Ukraine. Chemical Properties
Iron is soluble in dilute acids, where Fe (II) is produced in solution; more oxidising acids produce Fe (III) solutions and strongly oxidising agents (e.g. dichromate or concentrated nitric acid) produce a passive form of the metal, probably as a result of the formation of a coherent surface film of oxide.
Yield strength - y. Yield strength is defined in engineering as the amount of stress (Yield point) that a material can undergo before moving from elastic deformation into plastic deformation. Yielding - a material deforms permanently; The Yield Point is in mild- or medium-carbon steel the stress at which a marked increase in deformation occurs without increase in load. In other steels and in nonferrous metals this phenomenon is not observed.
Yield strength is routinely used as a basis of design for many products, including steel and ductile iron pipe. Tensile strength or ultimate tensile strength is the maximum stress reached during a tension test. In ductile materials the ultimate measured strength commonly will be reached before fracture, with a
Its minimum tensile strength is 172 Mpa. The gray cast iron is brittle, so there is no requirements to yield strength and elongation. Its hardness range is BH 170-229. Although gray iron has bad tensile strength, but their production costs are low, and easily manufactured, moreover, this material has good Vibration reduction, abrasive resistance, and low notch sensitivity. In addition, they could be machined easily.
In a sufficiently ductile material, when necking becomes substantial, it causes a reversal of the engineering stressstrain curve (curve A, figure 2); this is because the engineering stress is calculated assuming the original cross-sectional area before necking. The reversal point is the maximum stress on the engineering stressstrain curve, and the engineering stress coordinate of this point is the ultimate tensile strength, given by point 1.
The properties of ASTM A36 steel allow it to deform steadily as stress is increased beyond its yield strength. This ductility allows buildings to stand long after the limits of a structure have been met in an emergency, allowing the inhabitants to exit safely before collapse.
The compressive strength of mild steel is 4.75 25.2 tonnes / sq. cm. Its ultimate tensile strength is 5.51 11.02 tonnes / sq. cm. This clearly shows that mild steel is a better option than cast iron when it comes to ultimate tensile strength. However, cast iron has better compressive strength than mild steel.
Shear stress developed in a material subjected to a specified torque in torsion test for a circular shaft. It can be calculated using the expression. 15. Expected failure for Mild Steel and Cast Iron Specimens and reasoning: Fracture in torsion for ductile materials generally occur in the plane of maximum shear stress perpendicular to the axis yield stress of iron
I would avoid using "0" or zero as a yield strength, since you can get division by zero errors. In truth, the yield strength of cast iron would not be zero but would be at or very close to the tensile strength of the alloy, since the material behaves elasticly right up until failure.

Ductile iron has a minimum tensile strength of 60,000 psi and a minimum yield strength of 40,000 psi. 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.
Ductile iron itself can be broken down into different grades, each with their own property specifications and most suitable applications. It is easy to machine, has good fatigue and yield strength, while being wear resistant. Its most well-known feature, however, is ductility.
Yield stress of a solid is essentially the point at which, when increasing the applied stress, the solid first shows liquid-like behavior of continual deformation. If this is the case, then we can say that conversely, when decreasing the applied stress, solid-like behavior is first seenno continual deformation.
The yield strength of iron is around 80110 Mpa After galvanisation does it effect the yield strength or not that I am not aware of.
The popularity of grey cast iron components (gray iron castings) is because grey iron is one of the cheapest types of iron castings to produce. It has acceptable ductility, tensile strength, yield strength, and impact resistance for most applications.

Why is the yield strength calculated on the basis of 0.2% or 0.5% strain only? Which is preferred and why ? yield stress of iron For fragile materials, such as gray cast iron, the offset is 0.05% of the initial yield stress of iron
