BS 970-1 Grade 230M07 as rolled or normalized

A nickel chromium molybdenum steel with high strength and toughness. Supplied in Black round or squarebright round square, flat and hexagon. In addition to the above coding a condition coding may be applied. Supplied as black round bar and sections. Please refer to the relevant standards for important work. This is used in conjunction with a limiting section designation. Available as rolled or normalised in round, flat or hexagon form.

Supplied in as-rolled, annealed and hardened bw tempered condition in black square and round bar. Sections available black round, black square, bright round and black flat. Its chemical composition,provide the best all-round performance S. This Steel is especially good for free cutting, where a large volume of products are required. This grade is almost as popular as the grade the increased Mo content makes the steel more suitable for resisting pitting and crevice then Grade.


Suitable for higher strength applications when resistance to shock is required. A hard wearing medium carbon steel which can be hardened.

However this is difficult to do with EN1A and is not recommended. Available as rolled or normalised. Can be easily machined and welded. Available in heat treated condition e.

Supplied as black round or square bar and bright round or square, and hexagons. For continuous high temperature service in the range – oC. Used for gears axles and high strength studs.

It has excellent low temperature properties. Austenitic Non-Magnetic Cannot be heat treated but work hardens. Compared to normal Mild Steelbright Mild Steel provides tighter sectional tolerances, increased straightness, and a much cleaner surface.

The best source of material Information in the Web. Use this information at 2300m07 own risk. The number represents the manganese content x Suitable for stressed pins, shafts studs, keys etc. Used for high duty gears and shafts.

A mild steel used 230m0 general purposes. In the tables below the relevant sections are often thin and so the strength values are maximum values.

EN1A Mild Steel

Titanium stabilized, which offers improved welding properties. Supplied as rolled, annealed and hardened and tempered. A comprehensive reference text on european metals including Ref to latest Standards Matweb Used to make, shafts, racks, pinions, studs, bolts, nuts, rollers, etc.


Pocesses good resistance to scaling 9700 high temperatures. Can be induction hardened. Used food processing and catering equipment and automotive trim,car exhaust systems etc.

Mild Steel is used in mechanical engineering applications for parts that will not be subject to high stress.

Buy EN1A online at Metals4u. Typical applications include cutlery, surgical instruments, fasteners, valves, spindles and shafts. A case hardening mild steel suitable for general engineering applications. The values below are not comprehensive and must be used with extreme care. The term Mild Steel applies to all low carbon steel that does not contain any alloying elements in its makeup and has a carbon content that does not exceed 0. Used for gears, and high strength shafts etc.

Another benefit of bright Steel bars is a marked increase in physical strength over hot 97 bars of the same section. Martensitic Magneticcan be hardened and tempered to give improved tensile strength.

A medium strength steel. Yield Strength MPa Min. Due to the low carbon content of EN1A it is not recommended that this Mild Steel is used for welding.
