The Stainless Steel Family: Know What You Are Cutting
Tip 1: Know the Type of Stainless Steel You Are Cutting
Stainless steel is generally divided into three main types: austenitic, ferritic, and martensitic. On top of these, duplex stainless steel, precipitation-hardening stainless steel, and high-alloy steels with less than 50% iron were developed for specific needs.
1. Austenitic Stainless Steel — The Most Common and Most Versatile
Its matrix is mainly austenite (γ phase) with a face-centered cubic structure. It is non-magnetic and is mainly strengthened by cold working (which may introduce slight magnetism). It contains more than 18% chromium and usually about 8% nickel. AISI designates it with the 200 and 300 series — the most common being 304. Other designations include 1Cr18Ni9 and 0Cr19Ni9.
In one sentence: big output, wide use — found everywhere from food equipment to chemical plants and construction.
2. Ferritic Stainless Steel — Magnetic, Tough, Can’t Be Hardened by Heat
Its matrix is mainly ferrite (α phase) with a body-centered cubic structure. It offers good plasticity and toughness, and it is magnetic. It generally cannot be hardened by heat treatment, though cold working can strengthen it slightly. AISI designates it with 430 and 446; other designations include Cr17, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, and Cr28, with chromium content from 15% to 30%.
In one sentence: the magnetic “easygoing one” — easy to machine, but do not expect heat treatment to upgrade it.
3. Martensitic Stainless Steel — Hard, Wear-Resistant, Relies on Quenching
Its matrix is martensite, it is magnetic, and it has high carbon content, giving it good strength, hardness, and wear resistance. Mechanical properties can be adjusted through heat treatment. AISI designates it with 410, 420, and 440; other designations include 1Cr13 and 3Cr13.
In one sentence: the type that can “harden by quenching” — hardness and wear resistance are its strengths.
4. Duplex (Austenitic-Ferritic) Stainless Steel — The Best of Both Phases
Its matrix contains both austenitic and ferritic phases, with the smaller phase generally making up more than 15%. It is magnetic and can be strengthened by cold working. Common designations include 3RE60 (Cr18 type), SAF2304 (Cr23 type), SAF2205 (Cr22 type), SAF2507 (Cr25 type), and UNS S32304 (23Cr-4Ni-0.1N).
In one sentence: high strength and great corrosion resistance — cutting it takes a little more care.
5. Precipitation-Hardening Stainless Steel — Hardened Later, On Demand
Its matrix is austenitic or martensitic, and it can be hardened through precipitation-hardening treatment. AISI designates it with the 600 series — for example, 630, the well-known 17-4PH.
In one sentence: how hard you want it can be “customized” through treatment.
Tip 2: Check Hardness Before You Choose
Hardness is the fastest shortcut when you are learning how to choose the right bandsaw blade for stainless steel. For ordinary martensitic, austenitic, or ferritic stainless steel below 30HRC, standard requirements are easy to meet.
The blade choice changes completely when you are deciding how to choose the right bandsaw blade for stainless steel. For high-hardness grades, duplex stainless steel, or precipitation-hardening stainless steel, the blade choice changes completely — see the next tip.
Tip 3: Match the Blade Material to the Grade
For ordinary stainless steel below 30HRC, a TOLIYON bi-metal bandsaw blade is a solid choice. For higher efficiency and longer blade life, go with the TOLIYON TL Series. For high-hardness, duplex, or precipitation-hardening stainless steel, choose the TOLIYON TR Series carbide-tipped blade. See the full TOLIYON blade selection guide below.
Tip 4: Watch Out for Work Hardening
Stainless steel tends to work harden during cutting, which dulls teeth quickly and causes sticking and chipping. Matching the blade material, tooth geometry, and cutting fluid ratio to the specific grade is the key to longer blade life.
Tip 5: Get the Cutting Fluid Ratio Right
Use a 12%–15% concentration with bi-metal bandsaw blades and 15%–20% with carbide-tipped bandsaw blades to protect blade life and surface finish. Full details are in the TOLIYON blade selection guide.
Tip 6: Do Not Ignore Your Machine Condition
Even the best blade cannot perform well on a poorly maintained machine. Check wheel alignment, blade tension, guide arm condition, and feed control before you blame the blade.
Tip 7: Give Your Supplier the Full Picture
Whether you are learning how to choose the right bandsaw blade for stainless steel for the first time or fine-tuning an existing setupWhen asking for a recommendation, tell your supplier the material grade, workpiece size and shape, machine model, current blade specification, and cutting problems. The more you share, the more accurate the recommendation.
TOLIYON Blade Selection for Stainless Steel
The practical side of how to choose the right bandsaw blade for stainless steel. Once you know the stainless type and hardness, the blade choice becomes clear. Here is how TOLIYON matches the right bandsaw blade to your stainless steel:
Scenario 1: Stainless Steel Below 30HRC — TOLIYON Bi-Metal Bandsaw Blade
For ordinary martensitic, austenitic, or ferritic stainless steel below 30HRC, and when production efficiency requirements are not demanding, a TOLIYON bi-metal bandsaw blade is a solid, cost-effective choice that handles most standard jobs well.
Scenario 2: Higher Efficiency & Longer Blade Life — TOLIYON TL Series
When production efficiency and blade life matter more, choose the TOLIYON TL Series. Its optimized tooth geometry delivers great versatility and excellent performance in applications where tooth wear resistance is critical — so you cut faster and change blades less often.
Scenario 3: High-Hardness, Duplex & Precipitation-Hardening Grades — TOLIYON TR Series
For high-hardness stainless steel, duplex stainless steel, or precipitation-hardening stainless steel, choose the TOLIYON TR High-Efficiency General-Purpose Bandsaw Blade. Its high-hardness carbide tips resist chipping, and the large gullet design improves chip removal and tooth lubrication — built for the toughest stainless jobs.
Get the Cutting Fluid Ratio Right
Cutting fluid concentration directly affects blade life and surface quality. TOLIYON recommends:
- TOLIYON bi-metal bandsaw blades: 12%–15% concentration
- TOLIYON carbide-tipped bandsaw blades: 15%–20% concentration
Three Special Grades You Will Also Meet
904L — Super Austenitic Stainless Steel
Invented by Finland’s Outokumpu, 904L is a super austenitic stainless steel with 24%–26% nickel and less than 0.02% carbon, giving it excellent corrosion resistance. The old ASME SB-625 standard classified it as a nickel-based alloy; the new standard classifies it as stainless steel. China has only an approximate grade, 015Cr19Ni26Mo5Cu2.
440C — The Hardness Ceiling of Martensitic Stainless Steel
Among hard enable stainless steels, 440C has the highest hardness, reaching HRC57. You will often see it in cutting tools and bearings.
17-4PH — The Representative of Precipitation-Hardening Stainless Steel
With a hardness of about HRC44, it combines high strength, hardness, and corrosion resistance — but it cannot be used above 300°C.
The Bottom Line: Know Your Material First, Then Pick the Blade
Remember this order when you are figuring out how to choose the right bandsaw blade for stainless steel: identify the stainless type → check the hardness → choose bi-metal or carbide-tipped, then set the cutting fluid ratio correctly.

Frequently Asked Questions
If you are asking how to choose the right bandsaw blade for stainless steel, start with the material.
What is the best bandsaw blade for stainless steel?
For ordinary stainless steel below 30HRC, a high-quality bi-metal blade (like the TOLIYON TL Series) works well. For high-hardness, duplex, or precipitation-hardening stainless steel, a carbide-tipped blade (like the TOLIYON TR Series) is recommended.
Why does stainless steel wear out bandsaw blades so fast?
Stainless steel tends to work harden during cutting, which dulls teeth quickly. Matching the blade material, tooth geometry, and cutting fluid ratio to the specific grade is the key to longer blade life.
Can I use one bandsaw blade for all types of stainless steel?
Not ideally. Austenitic, ferritic, and martensitic stainless steels cut differently, and duplex or precipitation-hardening grades are even harder. Choosing by material type and hardness gives you better cutting quality and lower cost per cut.
What cutting fluid concentration should I use for stainless steel?
Use a 12%–15% concentration with bi-metal bandsaw blades, and 15%–20% with carbide-tipped bandsaw blades, to protect blade life and surface finish.
