We can achieve a surface hardness of HRC in C45 material by laser hardening.

Hardness of EN-8 grade material

Regards, vikas Vikas Kaushal – Chandigarh, India. We have taken C45 grade 4. If these are thin parts, you might be able to austemper or marquench them to reduce warpage.

Is there any process or suggestion to remove this dn8 while preventing from any crack? August 12th, 0 Comments. What is the optimum hardness we can expect?

I am a Commercial heat treater We received one tube mill roll for heat treatment The size is mm Dia. EN8 carbon steel is also readily machinable in any condition. What section thickness is your component?

EN8 Carbon Steel, 080M40 BS 970 Specification

Hello there, we make pins from 3 mm to 16 mm dia. And surface treatment is hard chrome plating.

I want to know how to achieve hardening in material EN8D. The main advantage of cold drawn Steel is that Steel can be brought closer to the finished machine size, reducing machining costs.


hhardness So can anyone help me with the exact formula to get proper hardness? Please re-read our note that abstract questions usually go unanswered ; if you re-frame them to include your own situation, they are far more likely to elicit responses. Please suggest how to rectify the problem. Please specify whether dwg. But EN8 steels can be further surface-hardened by induction processes, producing components with enhanced wear resistance.

Hardening EN8 & EN9 parts

We are doing similar components; also specify whether dwg. March 9, A. May 17, A. December 10th, 0 Comments. It hardnness 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.

EN8 mild steel – technical information

With C45 material can I get hardness hrc by case hardening? Mild Steel is used in mechanical engineering applications for parts that will not be subject to high stress. Is it in c scale or b scale? Good heat treatment results on sections larger than 65mm may still be achievable, but it should be noted that a fall-off in hzrdness properties would be apparent approaching the centre of the bar. November 8, A.

November 4, Laser Hardening. Rajishbabu auto parts – Gurgaon, India Q. Sorry, I have no knowledge of heat treatment. The surface of the material is reaching HRC but at the core of the material is getting only. November 29th, 0 Comments.

And the most equivalent is grade M40 steel in BS Hi, Devarajan, Gopi, Bharat. 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 Hardbess or a electrode. With limited information provided, it’s going to be hard to tell whether HRC is possible.


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.

Just send emails with detailed requests for EN8 carbon steels price. That hardness is the case hardness or the core hardness? All I can do is coach you on what I’ve learned from 20 years of running this forum: How to check the grade material hardness? We did arc quenching and oil quenching.

If it is the case hardness, is there any specification for core hardness?
