Stainless steel strips are the best material for making scraper and putty knives due to their outstanding properties, corrosion resistance, flexibility, surface finish, and durability.
Scrapers and putty knives are handy tools for homes and industries when doing DIY work.
Scrappers have stiff blades for good compound application on any surface, and putty knives have thinner and more flexible blades for scraping the surface.
They are mostly used to apply drywall, window glaze putty, and other fillers to close holes.
However, putty knives can remove excess putty and paint when doing repairs. The type of knife you choose will depend on how you want to use it.
Scraper and putty knives are mostly made from carbon steel strips and stainless steel strips.
Although carbon steel is more durable, it could rust if not properly maintained. The blade of a putty knife is constructed of stainless steel in the most long-lasting models.
A well-built knife with a stainless steel blade and a strong wood or nylon grip can last a lifetime.
Let’s keep reading.
What is stainless steel strip?
We make stainless steel strips with ultra-thin stainless plates using the slitting process in industries.
Stainless steel strips are often produced in long, narrow widths to satisfy the needs of various mechanical and industrial areas.
There are two standard methods for manufacturing stainless steel strips cold-rolling and hot-rolling.
Stainless steel strips can be separated from one another based on the processing method.
Stainless steel strips are widely utilized in various industries, including aircraft, petrochemicals, autos, textiles, electronics, household appliances, computers, and precision part processing.
They also have great strength and a precision surface polish.
Which grade of stainless steel is used for scraper and putty knife?
Putty knives and scrapers can be made well out of stainless steel.
Adding chromium and other alloying elements that boost corrosion resistance is a benefit of employing stainless steel.
Ferritic or martensitic stainless steels are typically used to create stainless steel putty knives and scrapers.
For producing putty knives, grades 3Cr13, 420J2 and 440 are commonly used.
Additionally, stainless steels that precipitation-harden have high corrosion resistance and hardenability qualities.
These are frequently employed in applications where corrosion is a significant concern.
Blades made of 17-7 PH precipitation-hardening stainless steel strips are commonly utilized.
The grades of 301 stainless steel strips and 201 stainless steel strips are also suitable for making stainless steel scrapers and putty knives.
What are scraper and putty knife?
The installation of drywall and windows can be made much simpler by using putty knives and scrapers, which can perform various scraping and smoothing tasks.
Applying compound around window pane edges cleanly with putty knives can assist the glass in staying in place.
Wider blades of scrapers make it easier to spread and scrape drywall compound.
Extra-wide blades on joint knives are designed to drywall seams and holes.
Putty knives made of stainless steel are incredibly durable and can spread evenly to give a polished appearance on a variety of surfaces.
Stainless steel scrapers are flexible tools that can be used for a number of scraping tasks, including window installations and drywall finishing.
What is the hardness of the stainless steel strip for putty knife?
The blade of a putty knife is constructed of stainless steel in outstanding models. A well-built knife with a stainless steel blade and a sturdy wood or nylon grip can last a lifetime.
Spreading high-quality steel blades will also have a “hollow ground” characteristic. This indicates that the blade is ground to be thinner at the handle, leading edge, and narrower in the middle.
For making putty knives and scrappers with stainless steel, the suitable hardness of stainless steel is from 92 HRB to 95 HRB. When choosing a material for scrapers and putty knives, you should keep these points in mind.
The material should be corrosion-resistant and have the ability to bend without breaking. It has sharpness and strength. While using the scrappers and putty knives, you have to use force on them so their material can resist deformation.
Benefits of stainless steel strips in scraper and putty knife
Stainless steel strip, formed through hot or cold rolling and used to make putty knives and scrapers, has various benefits over ordinary steel, including improved corrosion resistance, tensile strength, ductility, and extreme toughness.
Additionally, the entire recyclability of stainless steel strips in putty knives and scrappers is driving up demand among consumers concerned about the environment.
How to make one roll of stainless steel strip for a scraper and putty knife?
To make one roll of stainless steel strips for scrapper and putty knives, we must follow the process of manufacturing stainless steel strips.
Start this process by receiving and checking the raw material through quality control.
Then rolling and the annealing process are applied to this raw material by roller mills; after this process degreasing the surface of the steel strips by cleaning process.
For maintaining the straightness of stainless steel strips for the scraper and putty knife, these strips bends and gently stretches as it travels through a row of slightly oblique rollers.
For the required thickness and width, the slitting process applied on these strips with slitting machines can easily achieve the required specification for scrapers and putty knives.
