1.3243 Steel Forging Technology

The alloy element content of M35 steel is more than 22%.

It is higher than M2 steel about 30%.

It’s forging is difficult.

You need to pay attention to it as the same as M42 steel forging.

First of all, preheat it fully, the heat temperature is 1120℃ – 1150℃.

And the temperature of the beginning is 1000℃ – 1050℃, the ending of it is must higher than 899℃.

After forging, it should cold slowly and annealing on time to prevent cracking.

M35 Steel Annealing Process

If you case it up for the annealing after the forging, you will get a better result.

If you can not do that, just make it cold to the indoor temperature then make it in.

About the annealing process, just put it in the stove with the temperature which is lower than 500℃.

Then heat to 840-860℃, keep the temperature for four to five hours.

Furnace cooling to 500℃ below than out of it.

Cooling slowly in the annealing furnace.

After the annealing, its hardness is lower than 255HB.

In order to prevent oxidative decarburization happen, the annealing should be careful.

And there is an easy way can do that.

Just put some wood dust to the annealing furnace.

Notice for Quenching and Tempering

Preheat two times: 600℃, 860℃.

And the time of preheating is twice the time of heating.

The request of quenching is 10-12s/mm.

Needs the step hardening: 600℃→260-280℃→air cooling.

The temperature of secondary hardening is 535-540℃ around.

The hardness is bigger than 68HRC for after tempering.

But the factories do not want the hardness of cutting tool is more than 68HRC due to the request for production.

So it always is been tempering.

As we can see from the table, the best temperature for quenching is in the range of 1215-1225℃.

In this condition, it is suitable for annual cutting tools.

Its hardness is about 67-67.5HRC.

It satisfies the needs of high speed steel high speed steel for high strength, high hardness and high wear resistance.

M35 steel that been quenching at the temperature below 1190℃ is good material for cold work die and low-speed cutting tools.

And if it been quenching at the temperature higher than 1230℃ which will have a great red hardness.

It will be a good choice for turning tools and etc.

Quenching it in that way will cause overheating.

But it is not a trouble, the key is to control it in the right way.

Some cutting tools are overheating to be more useful.
