Hardnwss is therefore recommended that larger sizes of EN8 steel materials are supplied in the untreated condition, and that any heat treatment is carried out after initial stock removal.

So can you help for getting hardness hrc? Is it because of continuous hardening more than its capacity?

EN8 mild steel – technical information

Do you have a flame-hardening facility? Required case depth is 0.

What is the optimum hardness we can expect? What is the Hrc of EN-8 material kale pritam v – pune maharashtra india Ed. Yes, apart from my experience 0.

EN8 Mild Steel

Steel EN8 materials in its heat treated forms possesses good homogenous metallurgical structures, giving consistent machining properties. It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages. Hello there, we make pins from 3 mm to 16 mm dia.


August 12th, 0 Comments. All information presented is for general reference em8 does not represent a professional opinion nor the policy of an author’s employer. Hi sir, We are facing same problem re. But very few times do we achieve the target.

Hardenability is below 50 HRC e8n more than 6 mm from the surface, maybe you hardnesss get this number higher with brine quenching, but not 30 mm distance from surface to the center. We want hardness. I would advise dn8 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.

Our experience has been that when readers offer their help, they are hoping that posters will engage them in dialog, appreciating the opportunity to learn; but if the posters instead try to steer them into a “flash card quiz” of slightly changed materials, hardness, and dimensions, they invariably decline to play: From beautiful Pine Beach New Jersey: Rajishbabu auto parts – Gurgaon, India Q.

Mild Steel is used in haddness engineering applications for parts that will not be subject to high stress. May 24th, 0 Comments. All I can do is coach you on what I’ve learned from 20 years of running this forum: The surface of the material is reaching HRC but at the core of the material is getting only.

May 17, A. Part dimensions, thickness, quenchant, quench agitation, variation of chemistry from heat to heat What is the normal hardness of en8d material?


Pin diameter is 25 mm. Obviously it is possible to get hardness hrc in en 9, but please specify section thickness? Weight is approximately kgs. We did fn8 quenching and oil quenching. 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.

Is it in c scale or b scale? EN8 carbon steel is a common medium carbon and medium tensile steel, with improved strength over mild steel, through-hardening medium carbon steel. Information that you must supply to get further with your query: X mm What wn8 hardness can I get by Oil Quenching? We can achieve a surface hardness of HRC in C45 hardnesz by laser hardening.

Kindly give the solution for this. Please suggest how to rectify the hrdness. 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.
