What is stainless steel?

何謂不鏽鋼？

Stainless steel, also known as corrosion-resistant steel, is an alloy composed of iron, carbon, chromium, and other alloying elements. Chromium is the key element, typically present in concentrations ranging from 12% to 30%. The chromium reacts with oxygen to form a thin "chromium oxide" film, effectively blocking against corrosive factors like air, moisture and chemicals. This allows the stainless steel to perform well in harsh environments, significantly extending its service life.

不鏽鋼也稱為不鏽耐酸鋼，是由鐵、碳、鉻和其他合金元素混合而成的合金。 其中鉻是最關鍵的元素，通常含量在12%~30%之間，它與氧氣反應形成一層"氧化鉻"的薄膜，有效阻隔了空氣、水分、化學品等多種腐蝕因素的侵蝕，使得不鏽鋼在惡劣環境下仍能維持良好的使用狀態，大大延長了使用壽命。

The name "stainless steel" comes from its resistance to rust compared to ordinary steel. In addition to excellent corrosion resistance, stainless steel also possesses higher strength, hardness, and toughness, capable of withstanding certain levels of external force and impact, thereby avoiding deformation or damage during use.

而不鏽鋼如其名比起普通鋼更不容易腐蝕生鏽。除了優異的耐腐蝕性外，不鏽鋼還兼具了較高的強度、硬度和韌性，能夠承受一定程度的外力和衝擊，避免在使用過程中發生變形或破損。

The advantages of stainless steel are primarily manifested in the following aspects:

不鏽鋼的優點主要體現在以下幾個方面：

Long life cycle

生命週期長

Due to its high corrosion resistance and durability, stainless steel typically has a longer life cycle than ordinary metal materials. Even when exposed to humid, high-temperature, or chemically corrosive environments for extended periods, stainless steel can maintain its appearance and functionality, reducing the frequency of replacement and maintenance, thereby saving costs.

由於不鏽鋼本身具有很高的抗腐蝕性和耐用性，因此其生命週期通常比普通金屬材料更長。即使長期暴露在潮濕、高溫或化學腐蝕的環境中，不鏽鋼也能保持其外觀和功能，減少更換和維護的頻率，也能節省成本。

Superior rust and corrosion resistance

抗鏽抗蝕性強

Stainless steel contains a high proportion of chromium, making it a metal material with resistance to acids, alkalis, and high temperatures, making it suitable for various harsh environments. Whether in humid coastal areas, hot tropical climates, or industrial environments with high acidity and alkalinity, stainless steel can maintain its appearance and performance for extended periods, resisting rust and corrosion. This corrosion resistance makes stainless steel padlocks an ideal choice for both outdoor and indoor use.

不鏽鋼含有高比例的鉻，是一種耐酸、耐鹼和耐高溫特性的金屬材料，因此適用於各種惡劣環境。無論是潮濕的海濱地區、高溫的熱帶氣候還是具有高酸鹼度的工業環境，它都能長期保持外觀和性能，不易生鏽、腐蝕，而這種抗腐蝕特性讓不鏽鋼掛鎖成為了室外和室內使用的理想選擇。

Bright appearance and easy cleaning

外表光亮易清洗

The smooth surface of stainless steel padlocks is easy to clean, resistant to dust, dirt, or bacteria adhesion, and can easily maintain cleanliness and hygiene, reducing maintenance costs and workload.

不鏽鋼掛鎖其光滑的表面易於清潔，不易吸附灰塵、污垢或細菌，能夠輕鬆保持清潔衛生，降低了維護成本和工作負擔。

Adaptation to different environments

適應不同場域

Due to its excellent characteristics and performance, stainless steel padlocks are widely used in various locations and industries, such as industrial, commercial, outdoor, and residential areas. They are used to protect machinery and equipment, door locks, outdoor facilities, etc., providing excellent security and convenience.

由於其優異的特性和性能，不鏽鋼掛鎖被廣泛應用於各種場所和行業中。像是工業、商業、戶外及家居等，用於保護機器設備、門鎖、戶外設施等，提供了出色的安全性和便利性。

Where can stainless steel be used?

不鏽鋼可以用在哪?

The application range of stainless steel is extremely wide, and it can demonstrate its unique advantages in various environments. Whether it's in environments with direct sunlight, humid and rainy areas, or even deep in the ocean, stainless steel can maintain its performance and appearance, showcasing its excellent corrosion resistance and strength, providing reliable safety protection and operational efficiency for these occasions.

不鏽鋼的應用範圍非常廣泛，可以在各種環境中發揮其獨特的優勢。無論是在陽光直射的環境、潮濕多雨的地區，甚至是海洋深處，不鏽鋼都能夠保持其性能和外觀，並充分展示其優異的耐腐蝕能力和強度，為這些場合提供可靠的安全防護和使用效能。

Introduction to several application fields:

以下針對幾個場域來介紹：

→ Mountaineering Activities

→ 登山活動

Mountainous or high-altitude environments are variable, where factors such as moisture, oxygen, and solar radiation can corrode metal materials. Stainless steel possesses outstanding corrosion resistive, enabling it to maintain a bright appearance and resist rust, even in harsh mountain conditions. Therefore, it is commonly used in manufacturing mountaineering equipment, carabiners, etc.

山區或高海拔地帶的環境多變，大氣中的水分、氧氣、陽光輻射等因素都會對金屬材料造成侵蝕。不鏽鋼具有卓越的抗腐蝕性，即使在惡劣的登山環境長期使用也能保持光亮外觀、不易生鏽，因此常被用於製造登山裝備、鈎環等。

→ Coastal Areas/Fishing Boats

→ 海邊/漁船

Moist and high-salinity environments accelerate metal corrosion, but stainless steel exhibits good corrosion resistance in such conditions, maintaining a bright surface over the long term. Consequently, it is used in manufacturing coastal buildings, fishing gear, and ship accessories.

潮濕和高鹽度的環境很容易加速金屬的腐蝕，但不鏽鋼在這種情況下也能有良好的抗腐蝕性，可長期保持光亮的表面。因此常被用於製造海邊建築物、漁具以及船舶配件。

→ Motorcycles/Bicycles

→ 機車/腳踏車

Motorcycles and bicycles are often exposed to harsh weather conditions like heavy rain or sunlight, causing metal parts to rust. However, stainless steel's corrosion resistance and strength make it an ideal material for manufacturing motorcycle and bicycle parts such as screws, chains, frames, etc.

機車和腳踏車長期在戶外環境下使用，很常遇到暴雨或日曬等惡劣的天氣因素，所以機車上的金屬裝備容易生鏽，但不鏽鋼的耐腐蝕性和強度讓它成為製造機車和腳踏車零件的理想材料，例如螺絲、鏈條、車架等。

→ Camping

→ 露營

Camping activities often encounter humid, thunderstorm-prone, or extremely hot conditions, requiring materials with good corrosion resistance. Stainless steel is widely used in camping equipment such as nails, stoves, cookware, etc., maintaining good condition even in unfavorable weather.

露營通常在大自然中進行，也常會遇到潮濕、雷陣雨、酷熱等環境，所以就會需要使用到具有良好防腐蝕能力的材料。而不鏽鋼在露營用具中也被廣泛應用，例如釘子、火爐、鍋碗等，能夠在露營中即使氣候狀況不佳仍能保持良好的使用狀態。

→ Mailboxes

→ 信箱

Mailboxes exposed to outdoor elements like wind, sun, and rain need materials that resist corrosion. Stainless steel mailboxes not only resist corrosion better but also maintain an attractive appearance, providing reliable protection for your mail.

信箱長期暴露於風吹日曬雨淋的戶外中，需要使用能夠抵禦惡劣氣候的材料。而不鏽鋼製成的信箱不僅能較佳的抵擋風雨的侵蝕，還能保持外觀美觀、不易生鏽，為您的信件安全存放提供了可靠的保護。

→ Fence

→ 柵欄

Fences are used for decoration and security in areas like walls and yards, requiring long-term outdoor exposure. Stainless steel fences offer high corrosion resistance, aesthetics, and durability, making them an ideal fencing material.

柵欄是用於圍墻、庭院等場所的裝飾和安全設施，需要長期暴露在室外環境中。不鏽鋼柵欄不僅具有高抗腐蝕性能，也兼具美觀和耐久性，是一種理想的柵欄材料。

Whether in industrial, manufacturing or daily life, stainless steel's unique advantages are fully demonstrated, providing excellent protection and practical value for various environments.

無論是在工業製造還是日常生活，不鏽鋼的獨特優勢都能充分的展現，為各種場域提供出色的防護功能和實用價值。
