December 10th, 0 Comments. If the part is too thick to achieve adequate as quenched hardness, a hardnesz in material may be needed. Weight is approximately kgs. We posted your inquiries, gentlemen, but as you see no reader has taken the time to address them, despite thousands of people viewing them.

Hardness of EN-8 grade material

Kindly give the solution for this. Hello, I would like to know about the volume hardening of En9 to achieve the core hardness of BHN. Rajishbabu auto parts – Gurgaon, India Q. Just send emails with detailed requests for EN8 carbon steels price. If these are thin parts, you might be able to austemper or marquench them to reduce warpage. Hello there, we make pins from 3 mm to 16 mm dia. We want hardness. EN8 steel grade belongs to the standard of BSwhich is a standard for wrought steel for mechanical and allied engineering purpose.

X mm What maximum hardnness can I get by Oil Quenching? If you buy steel with a guaranteed hardenability band, you could better predict the heat treat response.


I would advise more quenching to avoid problem of distortion Just for sharing, had manufactured EN king pins which were toughened to 25 Rc at core then surface was induction hardened in polymer quenching to give 55 hrc hardness at surface to depth of. May 17, A. We will have hhardness EN8 carbon steel promotion at the end of almost every month. November 29th, 0 Comments.

EN8 Carbon Steel, 080M40 BS 970 Specification

In 60 mm thick you need, at least, some boron and chromium in your composition to improve hardening depth. The forged shaft diameter is 45 mm and length is mm with one end disc diameter of mm and length 30 mm. But very few times do we achieve the target.

When in its bright cold drawn condition the steel is able to endure higher levels of stress, particularly on smaller diameters. We can achieve a surface hardness of HRC in C45 material by laser hardening. Steel EN8 materials in its heat treated forms possesses good homogenous metallurgical structures, giving consistent machining properties.

September 30, A. If you already solved this, please let us know!

EN8 steel material is suitable for the all general engineering applications requiring a higher strength than mild steel such as:. Regards, vikas Vikas Kaushal – Chandigarh, India.

I am a Commercial heat treater We received one tube mill roll for heat treatment The size is mm Dia. Part dimensions, thickness, quenchant, quench agitation, variation of chemistry from heat to heat How to check the grade material hardness? Depending on answers to the above, there might be a heat treatment cycle that will give you what you want on En9, or it might be that you will need to change grade to one that has appropriate alloy content to allow hardening by less severe quenching.


Information that you must supply to get further with your query: Please specify whether dwg.

EN8 carbon steel is also readily machinable in any condition. And two steps are at both end with diameter 12g6. Please suggest the feasibility of achieving the een8 hardness and the process parameters. Is there a way that you can study what has been said and try that approach?
