En9 is a plain unalloyed medium-carbon steel.

Bardness carbon steel is a common medium carbon and medium tensile steel, with improved strength over mild steel, through-hardening medium carbon steel. 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 een8 hrc hardness at surface to depth of.

It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages. We do hardening process with docking and cooling in salted water. All information presented is for general reference and does not represent a professional opinion nor the policy of an author’s employer. Buy EN8 mild steel online at Metals4u. You need to case harden C45 up to HRC, I should say you can achieve that hardness without difficulties.

I want to know how to achieve hardening in material EN8D. Sorry there’s no quick answer. An EN8 material Sq. Modern EN8 bright Mild Steel contains a lot less carbon then it use to, this mean that it is possible to weld pieces up to 18mm thick without preheating using MIG wire SG2 or a electrode.

Thanks for the good detail on your component. We did arc quenching and oil hardnese. If material is case hardened which scale is used, e.

What our customers say What is the normal hardness of en8d material? EN8 steel is usually supplied untreated but also be able to be supplied to order in the normalized or finally heat treated, which is adequate for a wide range of applications.

Hardening EN8 & EN9 parts

But it didn’t help hadness. EN8 is suitable for all round engineering purposes that may require a Steel of greater strength. We posted your inquiries, gentlemen, but as you see no reader harness taken the time to address them, despite thousands of people viewing them. If you already solved this, please let us know! Information that you must supply to get further with your query: It therefore requires very severe cooling in the heat treatment cycle in order to get the sort of hardness that you want, and the thickness of the section in turn greatly affects the cooling rate that can be achieved.

May 24th, 0 Comments. And since this is a 0. With C45 material can I get hardness hrc by case hardening? In last lot used with same heat material hardness achieved 46 to 48 HRC, this month lot achieving hardness hagdness to 38 HRC only.

Hardness of EN-8 grade material

The main advantage of cold drawn Steel is that Steel can be brought closer to the finished machine size, reducing machining costs. May 17, A. Compared to normal Mild Steel, bright Mild Steel provides tighter sectional tolerances, increased straightness, and a much cleaner surface.

To what depth below the surface do you want HRc? What section thickness is your component? Required case depth is 0.

Is it because of continuous hardening more than its capacity? But very few times do we achieve the target.

Hardening EN8 / EN9 parts. Q&A’s, Problems & Solutions

We want hardness. Good heat treatment results on sections larger than 65mm may still be achievable, but it should be noted that a fall-off in mechanical properties would be apparent approaching the centre of the bar. Length hardnss 91 mm.


Normally this will not have major distortion issue. Mild Steel is used in mechanical engineering applications for parts that will not be subject to high stress.

All information presented is for general reference and does not represent a professional opinion nor the policy of an author’s employer. If the part is too thick em8 achieve adequate as quenched hardness, a change in material may be needed.

Regards, vikas Vikas Kaushal – Chandigarh, India. If anyone knows, kindly help. Chemical composition are C – 0. EN8 Mild Steel Buy EN8 mild steel online at Metals4u 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. November 4, Laser Hardening. January hardjess, 0 Comments. It is therefore recommended that larger sizes of EN8 steel materials are supplied in harness untreated condition, and that any heat treatment is carried out after initial stock removal.

I am a Commercial heat treater We received one tube mill roll for heat treatment The size is mm Dia. EN8 steel material is suitable for the all general engineering applications requiring a higher strength than mild steel such as:. Regards, Ted Mooney, P. Part dimensions, thickness, quenchant, quench agitation, variation of gardness from heat to heat Weight is approximately kgs. Another benefit of bright Steel bars is a marked increase in physical strength over hot rolled bars of the same section.
