To help you even further, we will teach you some of the best things for you to land on the best EN41B nitriding steel manufacturer!

What is EN41B Nitriding Steel?

EN41B nitriding steel is a type of steel comprised of main alloying elements, Chromium – Molybdenum – and Aluminum.

It’s distinguished to be a part of the BS 970 standard and is the material you want to use if you’re after good toughness, high wear resistance, and ductility.

Thanks to the nitriding process, all of these properties and traits are improved and developed. EN41B steel is actually one of the most popular and the most used types of free cutting steel that contains low carbon and manganese.

Can You Use EN41B Nitriding Steel Continuously?

Sample of EN41B tools and parts

Yes, as a matter of fact, EN41B steel is most suited and utilized repeatedly, that’s why you will find it most useful to be made and turned into different parts and components like studs, hydraulic fittings, bolts, nuts, dies, pins, and many more!

Understanding What NItriding Steel is

You can easily and simply understand nitriding because it’s one of the heating processes used in steel working.

It’s a procedure that spreads nitrogen onto the metal’s surface so that you get a surface that’s case hardened.

Where Do You Use Nitriding?

More often than not, the process of nitriding is performed on low-alloy, high-carbon types of steels.

Equivalent Grades of EN41B Nitriding Steel

If you ever come across the following steel grades, don’t immediately think that they’re 100% identical with EN41B nitriding steel.

They may be tagged as “equivalent” steel grades because of the present elements. However, they’re not 100% identical because the percentage of each element is not the same.

The equivalent grades of EN41B nitriding steel include, but are not limited to:

• BS 970: 1995: EN24T
• BS 970:1991: 817M40T
• SAE or AISI 1040
• 080M40
• 41CrAlMo7

What is the Density of EN41B?

Density of a particular material is calculated and computed via the mass in KG per volume cubic meter.

Steel’s density will vary depending on the alloying elements that are part of it. However, the typical range of steel density lies between 7,750 and 8,050 kg/m3.

Considering all of the alloying elements as well as the content structure of EN41B, its density is 8.08 g/cm3; or about 0.292 lb/in3.

What is the Melting Point of EN41B?

For the benefit of everyone, melting point is the temperature in which a particular material turns from solid to liquid.

In the simplest sense, it’s the temperature needed for an ice cube to become water again.

EN41B, being a steel grade that contains significant amounts of Chromium and Molybdenum, can have a melting point that’s substantially higher than its counterparts.

The melting point of EN41B is at 2,600 degrees Fahrenheit, or about 1,425 degrees Celsius. This is hot enough that it’ll turn the steel into a molten state.

What is EN19 Steel?

EN19 is a type of steel with decent amounts of tensile strength. It’s known to have high quality alloy steel, which paves the way for good levels of shock resistance and overall ductility.

You will find EN19 steel useful in environments where loading and pressure is present such as the gas and oil industry, the aircraft and automotive industry, the engineering and the machinery manufacturing industry, and many more!

EN40B’s Chemical Composition vs. EN41B’s Chemical Composition

Needless to say, EN40B and EN41B are two (2) steels that are from the same family.

While inexperienced people say that both of these metals have natural links to each other, they’re actually not the same.

In fact, they’re far from what many people expect them to be. To help you with it further, we’ll be giving you tables of each of these steel’s chemical composition.

EN40B’s Chemical Composition

Carbon	Chromium	Manganese	Molybdenum	Nickel	Phosphorous	Silicon	Sulphur
0.20 to 0.30%	2.90 to 3.50%	0.40 to 0.65%	0.40 to 0.70%	0.40% (max)	0.05% (max)	0.10 to 0.35%	0.05% (max)

As you can see, EN40B is dominated by Chromium and Molybdenum, which makes it eligible for better and higher hardenability, all the while improving corrosion and oxidation resistance.

EN41B’s Chemical Composition

Here’s the composition of all the chemicals and the alloying elements of EN41B.

Aluminum	Carbon	Chromium	Manganese	Molybdenum	Nickel	Phosphorus	Silicon	Sulfur
0.90 to 1.30%	0.35 to 0.45%	1.40 to 1.80%	0.65% (max)	0.10 to 0.25%	0.40% (max)	0.50% (max)	0.10 to 0.45%	0.50% (max)

If we put them side-by-side, we’ll see that the primary difference would be the aluminum content on the EN41B. What this does is it allows the steel to undergo galvanic corrosion, and it’s not the corrosion we know.

You can actually use galvanic corrosion to protect metallic parts and components by forming galvanic cells. This will require sacrificing the metal, and will be under a process called cathodic protection.

EN41B Material Price

How much is EN41B? How much money do you need for it? What is the budget that you need in order to make sure that it is the one you need?

EN41B manufacturing procedure or method

Knowing the rate or the price of EN41B isn’t that easy, in fact, if you search online, you might have an inaccurate calculation of it.

Here’s what you can do to figure out the prices and rates of EN41B:

Search Wholesale Websites

There are tons of wholesale websites you can run to if you’re not sure how much budget you need. There’s Alibaba, WholeSaleCentral, WorldWideBrads, and many more!

You’ll see good rates there, but of course, it’s still going to be better if you choose to work with a direct supplier/manufacturer of EN41B.

Moreover, you can build your relationship to the EN41B nitriding steel manufacturer if you choose to!

Ask Your Manufacturer/Supplier

Should the first option not work for you, and you have a couple of manufacturers on the list, don’t be afraid to ask them. Most EN41B steel manufacturers and suppliers will be capable of giving you a free quotation or a free estimate of whatever your orders are.

In fact, even if it’s your first time talking to that supplier, most of them have quote forms that are for free!

Don’t waste time searching the net to find out how much EN41B nitriding steels are. Even if you get it, you can’t be 100% sure that it’s accurate.

How much you can get it for can be completely inaccurate because the price of retail products and wholesale products are different, the prices of suppliers from different countries will definitely be different, and the like.

Is 41CrAlMo7 and EN41B NItriding Steel the Same?

One of the equivalent metals and materials that EN41B has is 41CrAlMo7. However, they’re not 100% the same, akin to other equivalents of EN41B nitriding steel.

However, they’re the same when it comes to the alloying elements that are contained and used to create the steel.

So, the next time you encounter 41CrAlMo7, don’t confuse it with EN41B. They are the same, but since they’re part of different standards, they can’t be 100% the same altogether.

Which Industries Utilize EN41B Nitriding Steel the Most?

While there’s a multitude of sectors and industries, there are some industries and business sectors that find it useful in some of their parts and their components as well.

EN41B steel is utilized in a wide array of sectors and industries

These include, but are not limited to:

• Marine and Maritime Applications
• Railroad and Transport Applications
• Aviation, Space, and Defense (ASD) Applications
• And Many More!

What is the Heat Treatment Process of EN41B?  

For the benefit of everyone, heat treatment is the process of altering or modifying the structure of a material by subjecting it to extremely high and fluctuating temperatures.

Unlike most steels, EN41B is heat treated at about 870 to 930 degrees Celsius. The procedure should be done slowly and constructively in order for it to successfully be treated and hardened.

What is the Hardness of EN41B Nitriding Steel?

Similar to different types and kinds of steels, EN41B nitriding steel would have different hardness levels depending on the heat treatment done to it.

For instance, if it’s annealed at temperatures ranging between 840 and 870 degrees Celsius, the hardness level that it can reach could be up to a maximum of 229 HB. After nitriding, it can reach a harness level of 1,000 to 1,100 HV.

Therefore, you really wouldn’t have any values on how the hardness of EN41B is. You can actually choose what type of procedure you can have it undergo.
