Unveiling the Chemistry and Mechanical Properties of 070M55 Steel Grade

[ad_1] The chemical composition of the 070M55 steel grade is typically as follows:

– Carbon (C): 0.52-0.60%
– Silicon (Si): 0.10-0.40%
– Manganese (Mn): 0.60-0.90%
– Phosphorus (P): max 0.040%
– Sulfur (S): max 0.050%

The mechanical properties of 070M55 steel grade are as follows:

– Tensile strength: 700-850 MPa
– Yield strength: 420-520 MPa
– Elongation: 10-16%
– Hardness: 180-220 HB
– Impact resistance: 27 J average (longitudinal)

These properties make 070M55 steel grade suitable for various industrial applications, such as shafts, gears, and high-strength bolts, where high tensile strength and good toughness are required.
