Difference in Properties of Cast Iron and Mild Steel

CompositionMelting PointCastabilityHardnessStrengthMachinabilityVibrationCast iron is an iron alloy with an amount of carbon superior to 2.11% is considered cast iron (whereas steels have an amount of carbon inferior to 2.11%).The carbon content in cast iron generally ranges from 2% to 4%.The most notable thing about its structure is that cast iron has graphite inclusions at the micro level.Mild steel is an Iron-carbon alloy containing less than 0.25 percent carbon which makes it more ductile and less hard thus rendering it unsuitable for structural work.See more on jashmetrologyAusforming Process and Applications Steel MetallurgyIf cost is not the primary factor,then these steels are very useful for applications which require high strength to weight ratio such as parts for under carriages of air craft,special springs and bolts.A steel-0.4% C,6% Mn,3% Cr,1.5% Si attains a strength of 3400 MPa with better ductility than obtained by conventional heat treatment.EN Steel series EN8,EN9,EN24,EN31stockist suppliersA general purpose steel for applications requiring added strength and superior tensile properties to mild steel specifications.EN9 :- 0.5% carbon steel giving higher tensile than EN8.Can be induction or flame hardened.EN19 :- 1% chromium molybdenum high tensile steel.File Size 100KBPage Count 5High Yield Steel High Tensile Strength Supplier CompanyHigh Yield Steel.From heavy transporters ,to steel structures and mobile cranes,our high yield steels are designed to work under incredible load stresses.Steels of this type are also supplied as special offshore grades to the offshore industry.Our structural grade material provides maximum strength (a minimum tensile strength of up to 1300 MPa),with good welding and bending properties.

Material selection and product specification

The achievement of a suitable strength whilst maintaining other properties has been the driving force behind the development of modern steel making and rolling processes.In the CEN product standards,the primary designation relates to the yield strength,e.g.S355 steel is a structural steel with a minimum yield strength (R eH) of 355 N/mm 2 Mechanical Properties of Steels for Cold-Formed Steel Mechanical properties of cold-rolled thin-walled steels at ambient temperature.Retention factors for the elastic modulus,yield strength,and ultimate strength were computed as the ratios of material properties at high temperatures to their values at ambient conditions,which is 20°C in this paper.Mechanical properties and microstructural features of AISI Mar 15,1999·Known for forming the highest level of strength in a steel,the martensite structure is rarely used in an untempered condition because a large number of internal stresses associated with the transformation cause the material to be lacking in ductility 6,7,8,however,low-temperature tempering is sufficient to reduce these stresses considerably without essentially changing the basic features of the

In these steels,yield strength is always defined as the 0.2% proof strength.The tensile strength/yield strength ratio (R m/R e) is a measure of a steels ability to work harden prior to fracture,and hence is also used as a measure of the ductility of the steel.Uniform elongation (A gt) is also a measure of a steels ability to deform prior RESEARCH REPORT 105High strength steels (yield strength >500MPa to typically 700MPa) are increasingly being used in offshore structural applications including production jack-ups with demanding requirements.Section F - EMJtime provide weldability and formability.Thus,they offer the advantages of higher strength-to-weight ratios,increased resistance to wear and abrasion,and in some cases improved resistance to atmospheric corrosion.These steels are produced under dozens of different trade names and are covered by a number to ASTM,SAE,and military
