What is Cruwear steel

What is Cruwear steel – Is Cruwear steel Good For Knife?

There are many steel alloys found in today’s world; Cruwear is one of them. Some of you may already know about Cruwear steel. If you are unaware of Cruwear steel, this guide is for you. In this guide, I will explain the chemical composition of Cruwear steel, the properties of Cruwear steel, and almost everything about Cruwear steel.

Let’s start with an in-depth review of the Cruwear steel.



What is Cruwear Steel?

Cruwear is one of the super steels that is made by Crucible Industries. It is popular for its balance between wear resistance, corrosion resistance, toughness, and hardness. It is an Air-hardening tool that is used for making knives, blades, and a wide variety of demanding tooling applications.

What is Cruwear Steel

Moreover, it is a good alloy for assembly line equipment. Common assembly tools are thread rolling dies, laminating dies, coining, and blanking dies.



Cruwear steel chemical composition

The elements in the Cruwear steel help the steel to reach a high level of hardness, wear resistance, corrosion resistance, and toughness. Each element is used for different purposes and has different features.

The elements which are included in the Cruwear steel grade are as follows:

Elements

Percentage 

Features

Chromium

7.5

Chromium increases the steel’s edge retention and strength. It also enhances the wear resistance and corrosion resistance of the steel.

Vanadium

2.40

It improves the steel’s hardenability and wears resistance.

Molybdenum

1.6

Molybdenum increases the steel’s machinability and strength.

Silicon

1.20

It increases the strength of the steel.

Tungsten

1.15

Tungsten improves the hardness and wears resistance of the steel.

Carbon

1.10

It increases the wear resistance and hardness of the steel. However, a high amount can decrease the steel’s strength. 

Manganese

0.35

Manganese increases the brittleness and hardness of the steel.

As you can see, the Cruwear steel has a high mixture of Chromium, Carbon, Tungsten, and Molybdenum, in its composition which offers the steel great hardness, toughness, and wear resistance.

Moreover, it is not stainless steel because it has not that much percentage of chromium (only7.5%) in its composition. For stainless steel, the minimum requirement of chromium is 12%; this steel is short of that requirement. Therefore, it is considered semi-stainless steel.

What is the Rockwell hardness of Cruwear steel?

Cruwear steel has great composition and a combination of elements, and because of this, it possesses great hardness. Moreover, it offers great toughness, corrosion resistance, and wear resistance. The Rockwell hardness of the Cruwear steel is around 64 HRC.



Cruwear steel properties

As you know, Cruwear steel has a great chemical composition and has a great hardness; it offers some amazing properties, which are as follows:

Edge Retention: As you know, Cruwear steel offers a high hardness which is around 64 HRC; this means Cruwear steel offers great edge retention.

Wear Resistance: Cruwear steel contains a mixture of carbon, tungsten, manganese, and chromium, which offer the Cruwear steel a great wear resistance.

Corrosion Resistance: Cruwear is not stainless steel. It is semi-stainless steel; therefore, it offers decent corrosion resistance.

Sharpness: Cruwear steel is easy to sharpen compared to other steel with close or same hardness.

Toughness: The composition of the Cruwear steel gives it an amazing toughness on the cost of corrosion resistance.

Is Cru-Wear steel good for Knives?

Yes, Cruwear steel is good for knives.

Cruwear steel offers amazing wear resistance, edge retention, hardness, and toughness. Moreover, it has decent corrosion resistance that can handle rust. These features make it a good option for EDC knives.

Cruwear steel is also budget-friendly, which makes it a perfect option for EDC knives. Another great benefit of Cruwear steel is that it is effortless to sharpen. So, if you are looking for toughness and hardness, Cruwear steel is for you.

Pros & cons of Cruwear steel
