EN 8
Carbon Steel EN 8 is a widely used engineering material known for its moderate tensile strength, good machinability, and affordability. It falls under the European standard BS 970, which specifies steel for mechanical and general engineering purposes. Let's delve into the specifics of EN 8 steel:
Steel Properties
Tensile Strength: Typically ranges from 560 to 710 MPa (81 to 103 ksi) depending on the heat treatment condition.
Yield Strength: Varies widely based on the heat treatment and can range from 380 to 580 MPa (55 to 84 ksi).
Elongation: Around 10-16% in the normalized or annealed condition.
Hardness: Typically, the hardness after heat treatment ranges from 170 to 220 HB (Brinell Hardness).
Application
Machine Components: Gears, shafts, crankshafts, and spindles requiring moderate strength and good machinability.
Automotive Parts: Camshafts, brackets, and connecting rods.
General Engineering: Bolts, studs, hydraulic fittings, and structural components.
