ISO9477 steel grade 410-620 is one high strength popular steel material in casting purpose. Generally it’s Low Alloy Carbon Steel.
ISO 9477 – 2015 High strength cast steels for general engineering and structural purposes
Grade 410-620 Casting Chemical Requirements and Mechanical Property:
All steel grade in ISO 9477 has below chemical requirements:
Silicon: 0.60 max
Sulfur: 0.025 max
Phosphorus: 0.030 max
Other chemical composition shall be selected by an agreement between the manufacture and the purchaser. But the Carbon Equivalent (CE) is defined as bellows:
CE=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15

Grade 410-620 Casting Mechanical Properties at Ambient Temperature:
TENSILE STRENGTH: 620-770 MPa
YIELD STRENGTH:410 MPa min
ELONGATION: 16% min
REDUCTION OF AREA: 40% min
IMPACT ENERGY: 20J
1MPa = 1 N/MM2
Ambient temperature is taken as 23±5 ºC

Metal Castings
Investment casting( precision casting, also named lost wax casting ) is an advanced metalforming process used to produce metal parts of the highest quality, functionality and cost-effectiveness. Investment casting( precision casting) is a one-to-one process in which one disposable pattern produces one metal part. When combined with modern production knowledge and technologies, Investment casting( precision casting) can be […]
In a low-alloy steel casting, the alloying elements are present in percentages greater than the following: Mn, 1.00; Si, 0.70; Cu, 0.50; Cr, 0.25; Mo, 0.10; V, 0.05; W, 0.05; and Ti, 0.05. Limitations on phosphorus and sulfur contents apply to low-alloy steels as well as carbon steels unless they are specified to be different […]
