Stainless steel, literally, is steel that won’t rust. Its full name is stainless steel acid-resistant steel. Steel grades that are resistant to weak corrosive media such as air, steam, and water or have rust properties are called stainless steels; and steel grades that are resistant to chemical corrosive media (acid, alkali, salt and other chemical corrosion) are called acid-resistant steels.
Due to their different chemical compositions, their corrosion resistance properties are also different. Ordinary stainless steel is generally not resistant to chemical corrosion, while acid-resistant steel is generally stainless steel. The term “stainless steel” does not refer to just one type of stainless steel, but to more than one hundred industrial stainless steels, each of which excels in its specific field of application. The key to success is to first understand the application and then determine the correct steel grade. Typically only six steel grades are relevant for building construction applications. They all contain 17-22% chromium, and the better grades also contain nickel. The addition of molybdenum can further improve atmospheric corrosion, especially corrosion resistance to chlorine-containing atmospheres.
Generally speaking, the hardness of stainless steel is higher than that of aluminum alloy, and the cost of stainless steel is also higher than that of aluminum alloy.
从字面上讲,不锈钢是一种不会生锈的钢。它的全称是不锈钢耐酸钢。耐空气、蒸汽、水等弱腐蚀性介质或具有防锈性能的钢材称为不锈钢;耐化学腐蚀介质(酸、碱、盐和其他化学腐蚀)的钢种称为耐酸钢。
由于其化学成分不同,其耐腐蚀性能也不同。普通不锈钢一般不耐化学腐蚀,而耐酸钢一般是不锈钢。“不锈钢”一词不仅仅是指一种不锈钢,而是指一百多种工业不锈钢,每一种都有其独特的应用领域。成功的关键是先了解应用,再确定正确的钢牌号。通常只有六种钢材等级与建筑应用有关。它们都含有17-22%的铬,较好的品级还含有镍。钼的加入可以进一步改善大气腐蚀,特别是对含氯大气的腐蚀性能。
一般来说,不锈钢的硬度比铝合金高,而且不锈钢的成本也比铝合金高。

Advantages of stainless steel gua sha plate
More durable. Compared with natural stone gua shastones, stainless steel gua sha tools are more durable. Because the natural stone guasha board is easy to break due to its material. It will break even if dropped from shoulder height. But stainless steel gua sha scraper does not have this problem.
A more uniform shape. This is due to the plasticity between materials. Natural stone, the texture and density of each piece are not the same, so it is difficult to achieve uniform quality and shape during processing. But the stainless steel hanging gua sha board solves this problem.
More stable supply. Natural stones are affected by the amount of mining, reserves and even policies, and the amount of rough stones that can be supplied in the market will fluctuate greatly. But stainless steel is relatively more stable.
Benefits Of Stainless Steel Gua Sha
Gua Sha is a traditional Chinese natural therapy that uses instruments such as ox horn, jade, and fire pots to scrape on relevant parts of the skin to unblock meridians and invigorate blood circulation and remove blood stasis. Gua Sha has different effects, including detoxification and treating colds.
The process of gua sha (scraping the skin to make gua sha) can make the local tissues highly congested, the vascular nerves are stimulated to make the blood vessels dilate, the blood flow and lymphatic fluid increase, the phagocytosis is enhanced, so that the waste and toxins in the body are accelerated and the tissue cells are nourished, thus purifying the blood and increasing the resistance, which helps to alleviate the disease and promote recovery.
The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things.
不锈钢瓜沙板的优点
更耐用。与天然石材瓜砂相比,不锈钢瓜砂工具更耐用。因为天然石材的瓜沙板由于材质的原因很容易断裂。如果从肩膀那么高的地方掉下来,它就会收支平衡。但不锈钢瓜沙刮板不存在这个问题。
更均匀的形状。这是由于材料之间的可塑性。天然石材,每一块的纹理和密度都不一样,所以在加工过程中很难达到均匀的质量和形状。而不锈钢挂瓜沙板解决了这个问题。
更稳定的供应。天然石材受开采量、储量甚至政策的影响,市场上可供应的原石量会出现较大波动。但是不锈钢相对来说比较稳定。
不锈钢瓜沙的好处
瓜沙是一种中国传统的自然疗法,用牛角、玉器、火盆等工具刮擦皮肤的相关部位,以疏通经络、活血化瘀。瓜沙有不同的功效,包括解毒和治疗感冒。
刮痧(刮皮作瓜痧)的过程可使局部组织高度充血,刺激血管神经使血管扩张,使血流和淋巴液增加,吞噬作用增强,使体内的废物和毒素加速,使组织细胞得到营养,从而净化血液,增加抵抗力,有助于缓解疾病,促进康复。
事实上,你会发现很多人在很多东西上都买不到好价钱。
