Iron Casting Hardness and Tensile Strength

Iron Casting Hardness and Tensile Strength

The first indicator of quality in iron castings is the mechanical properties, and there are two main methods to test the mechanical properties, one is the tensile strength test, and the other is the hardness test. Tensile test is to test the tensile strength, yield strength and elongation of metal castings, and hardness test reflects the material elasticity, plasticity, strength, toughness and sp.info Gray Iron Castings Hardness Requirements6 rows · Gray iron casting, grade ASTM A48, 30B is produced according to standard ASTM A48, and the sp.info

    • See all 9 rows on iron-foundry Cast Iron Mechanical Properties – Tensile Strength Tensile strength is important in the use of brittle materials (cast iron) more than ductile materials (ductile cast iron). In ductile materials the ultimate measured strength commonly will be reached before fracture, with a lower stress level recorded at the point of fracture.
