For the usual run of cast iron, The yield stength almost coincides with its fracture strength - cast iron is very brittle and fractures at usually more than 20000 pounds per square inch. DUCTILE cast iron is one of the several irons that DO yield before cracking.
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
Cast Iron because of its strength and mass
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
The yield strength of pure iron (Fe) is typically around 250 MPa. This value can vary depending on factors such as purity, temperature, and processing.
The breaking strength is always greater than the yield strength.
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
what is characteristic yield strength
Cast Iron because of its strength and mass
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
Tensile yield point or yield strength
The yield strength in this case is equal to the ultimate tensile strength, which is about 0.9-3 MPa without any reinforcement.
Percent yield is calculated by dividing the actual yield by the theoretical yield and multiplying by 100. The theoretical yield can be calculated by stoichiometry. In this case, the theoretical yield of iron would be 43.3g. Therefore, the percent yield would be (15.0g / 43.3g) x 100 = 34.6%.
The yield of production of sponge iron is calculated by dividing the weight of sponge iron produced by the total weight of iron ore initially taken for the process, and then multiplying by 100 to get the percentage yield. It is important to consider losses during the process to get an accurate yield calculation.
