1.6511 Steel Buying Guide

Are you looking for a guide on how you can purchase the best quality 1.6511 steel in the market? Can’t you find a 1.6511 manufacturer and supplier you can fully trust?

Don’t worry, in this guide, we’ll walk you through all the information you need in purchasing 1.6511 steel. We’ll teach you about what it is, how you can use it, and what benefits you can get in using it, and many more!

Understanding What 1.6511 Steel Is

In the simplest and most basic ways possible, 1.6511 steel is a type of alloy steel that has undergone high quality quenching and tempering.

With its composition, you can easily figure out that it’s part of the medium-carbon alloy steel family, that’s been made via oil quenching.

The properties of the 1.6511 steel are nearing identical to that of the AISI 4340 – or 36CrNiMo4 alloy structural steel. To help you grasp it further, here’s the chemical composition of 1.6511 steel…

Chemical Composition of 1.6511 Steel

1.6511 steel is composed of the following alloying elements and compounds:

Carbon (C) – 0.32 to 0.4%	Phosphorus (P) – ≤0.035%	Molybdenum (Mo) – 0.15 to 0.30%	Manganese (Mn) – 0.50 to 0.80%
Chromium (Cr) – 0.90 to 1.20%	Silicon (Si) – ≤0.40%	Sulfur (S) ≤ 0.35%	Nickel (Ni) – 0.90 to 1.20%

These are the alloying elements present in 1.6511 steel. The “range” is present because certain requests of clients want the maximum percentage of Silicon, while there are businesses that need just the minimum.

NOTE: This guide is only a rough range of the alloying elements present in the material. There are times that it’s exact and there are times that it’s not.

36CrNiMo4 Equivalent Material

Some of the materials you can associate 1.6511 steels to include EN 24, GB 40CrNiMo, DIN SNCM 439, AISI 4340 steel, and many more!

NOTE: They’re similar because of the alloying elements composition – but they’re not identical.

Do You Need 1.6511 Steel?

If you’re trying to look for a kind of steel that you can purchase and utilize for business needs, you might be considering 1.6511 steel.

But do you really need it? In order for you to figure out whether or not it’s the kind of alloy steel you need, here are some information to know about it:

Is 1.6511 Steel Heat Treated?

Yes, akin to the other grades of medium-carbon steels, 1.6511 steel is heat treated.

Heat treatment processes done to 1.6511 steels

In fact, they’re treated and processed in the following methodologies:

• Hardening – at 850 to 860 degrees Celsius and is oil-cooled
• Soft annealing at 650 to 710 degrees Celsius and is furnace-cooled
• Forging at 850 to 1050 degrees Celsius and is furnace-cooled

NOTE: The max hardness 1.6511 steels reach during soft annealing is 250 HB.

What is the Hardness Level of the 1.6511 Steel?

If we were to look at the Brinell hardness level of the 1.6511 steel, it sits at the 414 range. It has a Rockwell hardness level of 22.

What is the Tensile Strength of 1.6511 Steel?

The tensile strength of 1.6511 steel sits at 655 MPa, with a melting point that shoots up to 1,416 degrees Celsius.

1.6511 steel possesses high levels of tensile strength

It’s not that hard, but it can withstand force and impact at a good quality.

What is 41L40 Steel?

The 41L40 steel alloy is a type of steel that’s comprised of Chromium-Molybdenum.

It also possesses added lead, which is the reason why it’s simpler and easier to machine.

But, because of this, their impact strength is a lot lower in level compared to other steel alloys – compared to 1.6511 steels.

Is 1.6511 Steel Similar to AISI 4340?

A lot of people think that the AISI 4340 steel is 100% identical to the DIN 1.6511. While they’re closely related, they actually have differences when it comes to chemical composition.

For instance, AISI 4340 has Molybdenum levels that range between 0.20 and 0.30%, but in DIN 1.6511, it’s just 0.15 to 0.30%.

These differences might seem minimal to the naked eye, but when you put more though into it, you’ll actually find that it does really make a difference.

Supply Forms of 1.6511 Steel

You can get and be supplied with 1.6511 steel in many different forms, shapes, and sizes.

The different forms and shapes of 1.6511 steel you can purchase

The most common forms of supply are in the shapes of: square form, plate form, round bar form, or in sheet form.

Note though that you can get 1.6511 steel in other shapes and forms, too! Should your 1.6511 steel manufacturer offer customization, you can even have it custom-made to tailor-fit your needs!

Where Can You Apply 1.6511 Steel?

You can choose to utilize 1.6511 steel for a wide variety of applications. You can use its toughness, stress, and impact resistant for mechanical engineering and for automotive applications.

Thanks to its properties, you can also use it for:

• Rotor Shafts and Blades
• Crankshafts
• Fears
• Turbine Shafts
• Turbojet Engines
• Heavy Machinery and Industrial Units
• And Many More!
