Grade 3Cr13 stainless steel strip and 440 stainless steel strip are both martensitic stainless steel alloys that are used in knife manufacturing applications.
There are different grades and types of stainless steel strips in the market. In this article, we will be looking at the differences between the grade 3Cr13 stainless steel strip and the grade 440 stainless steel strip.
Let’s keep reading.
What Is Grade 3Cr13 Stainless Steel Strip?
Grade 3Cr13 stainless steel strip refers to a durable metal which is very common in different industries.
This 3Cr13 stainless steel strip contains high levels of carbon content and is capable of withstanding high temperatures without undergoing any discoloring and deforming.
Since stainless steel is resistant to corrosion, it can always be left out doors for longer periods without encountering any rust or getting damaged by the Ultra violet rays.
3Cr13 stainless steel strip is among the most popular grade of stainless steel strips.
It can be used in a wide variety of applications and industries since it is very sturdy and durable.
This stainless steel strip has low high carbon steel which makes it resist corrosion with ease.
It is also capable of resisting wearing out much better when compared to other metals such as the aluminum and the iron.
3Cr13 stainless steel strip is an excellent choice of metal for anyone who is in need of something that will last a long time.
What Is Grade 440 Stainless Steel Strip?
Grade 440 stainless steel strips is well known for its moderate resistance to corrosion, high strength and hardness levels and high resistance to tear and wear.
This 440 stainless steel strips contains high amounts of carbon and it is a martensitic type of stainless steel.
440 stainless steel strips can easily attain the highest wear resistance, hardness and strength after undergoing heat treatment when compared to all the stainless steel strips.
The high amount of carbon in it is behind these features which makes it a perfect suit for use in the manufacture of valve parts and ball bearings.
3Cr13 Stainless Steel Strip Vs. 440 Stainless Steel Strip Comparison
Despite 3Cr13 stainless steel strip and 440 stainless steel strip being made from almost same material which is the stainless steel, these two have a slight difference in their element composition.
The alloy elements in 3Cr13 stainless steel strip and 440 stainless steel strip are the same although they vary in amount. 440 stainless steel strips contains more chromium and carbon when compared to 3Cr13 stainless steel strip.
However, the 440 stainless steel contains less silicon and manganese than 3Cr13 stainless steel strip. They both contain the same amount of nickel.
440 stainless steel strips are known to be much harder due to the high amount of chromium and carbon content.
The slight difference in the hardness ensures 440 stainless steel strips are capable of achieving better edge retention and wear resistance than the 3Cr13 stainless steel strip.
In case you are in the market of selling products with superior cutting features, then it is advisable that you go for the 440 stainless steel.
Resistance to wear and edge retention is the only features 440 stainless steel strip has more than the 3Cr13 stainless steel strips.
What Is The 3Cr13 Stainless Steel Strip Hardness?
3Cr13 stainless steel strip does contain lower levels of carbon and high chromium steel.
By considering the composition of 3Cr13 stainless steel strip, you can easily lower your expectation on its level of hardness.
Despite large amounts of chromium being of great help with hardness, it will need more amount of carbon than the 3Cr13 stainless steel strip to enable it achieve higher results.
3Cr13 Stainless Steel Strip has a hardness of between 50HRC to 55 HRC. All its elements do contribute to its level of hardness.
Its level of hardness makes it a soft to medium stainless steel strip.
Is 3cr13 Stainless Steel Strip Good For Knives?
The 3Cr13 stainless steel strip is capable of making great knife blade materials. It is a very common material in the manufacture of vegetables and utility knives in the market.
However, 3Cr13 stainless steel strip is not the number one choice when it comes to the manufacture of kitchen knives for multipurpose since it cannot hold its sharp cutting edges for longer periods.
The 3Cr13 stainless steel strip knives are also not excellent for outdoor use despite being capable of withstanding the impact from cutting dense and heavy objects.
These 3Cr13 stainless steel strip knives are known to get dull quickly rendering them useless. 3Cr13 stainless steel strip suits some of the common cutting needs in a kitchen.
Which One Between Cr13 Stainless Steel Strip And 440 Stainless Steel Strip Is Better?
3Cr13 stainless steel strip does have optimal toughness that makes it suitable for several applications especially in the kitchen.
Knives made from 3Cr13 stainless steel strip will not break or chip with ease whether outdoors or in the kitchen as it is impact resistant making it capable of making robust cuts without any flinch.
3Cr13 stainless steel strip is well known for its ability to resist rust. The high levels of chromium content and low levels of carbon in 3Cr13 stainless steel strip ensure it has a great resistance to corrosion levels.
3Cr13 stainless steel strip will help in keeping the knife blade free from oxidation even when exposed to harsh weather conditions.
440 stainless steel strips is known to be much harder than the 3Cr13 stainless steel strip due to the higher levels of carbon and chromium contents.
In case you are in the market for a stainless steel strip with superior cutting capabilities, then this 440 stainless steel strip is the better option to consider.
At HZW, we have knowledgeable and experience personnel who will take their time and explain to potential customers the differences between grade 3Cr13 stainless steel strip and the grade 440 stainless steel strip to help them make an informed decision on which stainless steel strip grade suit their project best.
