Product Desciption
Hot Forged Round Bar SAE 1040 EN8/080M40 Rolling Mild Steel
1040 also know as 080M40,EN8. Unalloyed medium carbon steel. EN8 is a medium strength steel, good tensile strength. Suitable for shafts, stressed pins, studs, keys etc. AISI 1040.
Available as normalized or rolled. EN8 is supplied as round drawned, round hot rolled, hexagon, square, flats and plate.1040 is usually supplied untreated but can be supplied to order in the normalized or finally heat treated (quenched and tempered to "Q" or "R"properties for limiting ruling sections up to 63mm), which is adequate for a wide range of applications. Please refer to our selection guide for comparisons.
