Thép không gỉ vs. Titanium Cắt

1. Giới thiệu

Cutting boards play a pivotal role in kitchen hygiene and food preparation.

They protect countertops, preserve knife edges, and help prevent cross-contamination.

Chưa, selecting the right cutting-board material involves more than aesthetics; it directly impacts durability, sự an toàn, and maintenance efforts.

Trong bài viết này, we compare stainless steel and titanium cutting board across material properties, cutting performance, Vệ sinh, tuổi thọ, trị giá, thiết kế, và các ứng dụng trong thế giới thực.

Cuối cùng, you’ll have a clear framework for choosing the ideal board for your culinary needs.

2. Tính chất vật chất

thép không gỉ

Thép không gỉ cutting boards typically use điểm 304 Và 316.

Cấp 304 comprises approximately 18% crom (Cr) Và 8% Niken (TRONG), while grade 316 raises molybdenum (MO) content to about 2%, boosting resistance to chlorides.

Both grades achieve a Rockwell hardness of B80–B95 (≈170–220 HV) and possess a density of 7.8 g/cm³.

Chromium drives corrosion resistance by forming a passive Cr₂o₃ lớp. When scratched, that film self-heals within minutes in oxygenated environments.

Thanks to this passivation, stainless boards resist rust and staining even after years of kitchen use.

Titan

Titan cutting board come in commercially pure (Cp) điểm or the alloy Ti-6al-4V.

CP titanium offers a tensile strength of 300Mạnh500 MPa, a hardness of ≈150 HV, and a density of 4.5 g/cm³.

Ngược lại, Ti-6Al-4V—employed where extra durability matters—reaches 900 MPA tensile strength and ≈350 HV độ cứng.

Titanium’s native titan dioxide layer forms spontaneously, providing unmatched corrosion resistance in all pH conditions, including saline and acidic environments.

That oxide film remains stable even under extreme thermal or chemical exposure.

3. Cutting Performance & Knife Friendliness

Surface Hardness and Wear Resistance

Stainless steel boards achieve 200–220 HV, sufficient to resist scoring but hard enough to dull knives over time.

Titanium alloy boards, Tại ≈350 HV, endure heavy use with minimal wear. Tuy nhiên, pure titanium’s lower hardness (~150 HV) makes it more susceptible to scratches.

Effects on Knife Edge Retention

Frequent chopping on stainless steel accelerates blade dulling: knives lose approximately 20–30% of edge sharpness after 500 chops.

Titanium alloy boards reduce that loss to 10–15%, thanks to titanium’s lower abrasion coefficient.

Yet both materials remain less forgiving than wood or plastic; steel-or-titanium boards trade knife longevity for hygienic benefits.

Traction and Safety

Stainless and titanium surfaces can become slippery when wet. Manufacturers often integrate machined grooves hoặc textured patterns to enhance grip.

Ví dụ, Một 1 mm bead-blasted finish increases coefficient of friction by 25%, reducing slip-related accidents.

4. Vệ sinh & An toàn thực phẩm

Ensuring a cutting board resists bacterial growth and cross-contamination ranks among the most critical considerations in any kitchen.

Both stainless steel and titanium offer inherent advantages over porous materials like wood or certain plastics, yet they differ in key hygiene metrics.

Non-Porosity and Bacterial Harboring

Both metals present không xốp surfaces that deny bacteria the microscopic crevices they need to colonize.

In independent lab tests, stainless steel retained fewer than 10 colony-forming units (CFU) per cm² của Escherichia coli after a standard wash cycle,

while titanium registered effectively 0 CFU/cm² under identical conditions.

Do đó, neither surface harbors moisture or food particles, and both surpass polymer boards (which can trap up to 1,000 CFU/cm²) in microbial cleanliness.

Cleanability and Sterilization

Hơn thế nữa, stainless steel withstands repeated chemical and thermal sanitation.

Commercial kitchens routinely sterilize stainless boards in autoclaves at 121 ° C. or with chlorinated sanitizers—practices that leave no lasting surface damage.

Tương tự, titanium’s robust Tio₂ oxide film resists pitting or etching from aggressive detergents and bleach, enabling both dishwasher and UV-light sanitizing without degradation.

Resistance to Staining, Odors, and Cross-Contamination

Hơn nữa, both materials resist absorption of pigments and odors.

Trong a 500-hour accelerated staining test, cấp 316 stainless steel showed zero color transfer from tomato juice and turmeric,

and titanium exhibited no surface discoloration or retained odors even after direct contact with garlic and onion extracts.

This non-reactive behavior ensures that a single board can safely prepare disparate food types—meat, fish, trái cây, and vegetables—without risk of flavor carryover or chemical leaching.

By combining non-porous metallurgy with exceptional cleanability and stain resistance, stainless steel and titanium cutting boards deliver the food-safety performance that professional and home kitchens demand.

5. Độ bền & BẢO TRÌ

Scratch Resistance and Deformation

Stainless steel deforms under loads above 500 N, showing shallow dents. Titanium alloy survives loads up to 800 N without permanent deformation.

Pure titanium dents at 300 N, so users often prefer Ti-6Al-4V in high-stress environments.

Dimensional Stability and Warping

Both metals resist warping under thermal cycling between –20 °C to 80 ° C..

In prolonged dishwasher cycles, cấp 304 boards exhibit 0.1% dimensional change, whereas titanium remains unchanged.

Các giao thức làm sạch

Stainless steel boards clean effectively in commercial dishwashers and resist acidic cleaners.

Titanium also stands up to dishwashers but requires no post-wash passivation, since its oxide layer never degrades.
