Нержавіюча сталь проти. Титанова обробна дошка

1. Вступ

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

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

Ще, selecting the right cutting-board material involves more than aesthetics; it directly impacts durability, безпека, and maintenance efforts.

У цій статті, we compare stainless steel and titanium cutting board across material properties, cutting performance, гігієна, довговічність, вартість, дизайн, та реальні програми.

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

2. Матеріальні властивості

Нержавіюча сталь

Нержавіюча сталь cutting boards typically use оцінка 304 і 316.

Сорт 304 comprises approximately 18% хром (Cr) і 8% нікель (У), 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 шар. 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.

Титан

Титан cutting board come in commercially pure (Cp) оцінка or the alloy TI-6AL-4V.

CP titanium offers a tensile strength of 300–500 МПа, a hardness of ≈150 HV, and a density of 4.5 g/cm³.

Навпаки, Ti-6Al-4V—employed where extra durability matters—reaches 900 MPA tensile strength and ≈350 HV твердість.

Titanium’s native титановий діоксид 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, в ≈350 HV, endure heavy use with minimal wear. Однак, 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 або textured patterns to enhance grip.

Наприклад, a 1 mm bead-blasted finish increases coefficient of friction by 25%, reducing slip-related accidents.

4. Гігієна & Безпека харчових продуктів

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 непорочний 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 на Escherichia coli after a standard wash cycle,

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

Отже, 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

Більше, 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.

Аналогічно, 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

Крім того, both materials resist absorption of pigments and odors.

В 500-hour accelerated staining test, сорт 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, фрукти, 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. Міцність & Технічне обслуговування

Scratch Resistance and Deformation

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

Pure titanium dents at 300 П., 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, сорт 304 boards exhibit 0.1% dimensional change, whereas titanium remains unchanged.

Протоколи очищення

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.
