濟南不銹鋼電梯門套廠家:不銹鋼電梯門套材質(zhì)有哪幾種?
以前,很多地產(chǎn)項目,僅一層安裝電梯大門套,其他層電梯廳門入口,并無前飾。但隨著地產(chǎn)的高端化,越來越多的電梯廳門入口不再是大白墻,而是全部層采用廳門包套。而大門套的選擇最常見的就是不銹鋼材質(zhì)。但電梯不銹鋼大門套到底該如何選擇,首先我們先從材質(zhì)說起。
In the past, many real estate projects only installed elevator door covers on one floor, and there were no front decorations at the entrance of the elevator hall doors on other floors. But with the high-end development of real estate, more and more elevator hall entrances are no longer large white walls, but all floors are covered with hall door covers. The most common choice for the large door frame is stainless steel material. But how to choose stainless steel door covers for elevators? First, let's start with the material.
一、 不銹鋼是什么鋼?
1、 What is stainless steel?
不銹鋼是鋼的一個種類,鋼是指含有碳(C)量在2%以下的稱之為鋼,大于2%是鐵。鋼在冶煉過程中加入鉻(Cr)、鎳(Ni)、錳(Mn)、硅(Si)、鈦(Ti)、鉬(Mo)等合金元素改善了鋼的性能使鋼具有了耐腐性(即不上銹)就是我們常說的不銹鋼。
Stainless steel is a type of steel, which refers to steel containing less than 2% carbon (C) and more than 2% iron. Adding alloying elements such as chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo), etc. during the smelting process improves the properties of steel and gives it corrosion resistance (i.e. no rust), which is commonly known as stainless steel.
二、為什么不銹鋼有不同的鋼號?
2、 Why are there different grades of stainless steel?
不銹鋼通常被分為201、202、301、304、309s、310s、410、420、431等多種型號。其中,201、202、301、304、309s、310s屬于奧氏體不銹鋼,不含有磁性,可耐多種介質(zhì)腐蝕。410、420、431則屬于馬氏體不銹鋼,具有磁性、強度高,但塑性和可焊性較差。其中硫磷含量是一很重要指標(biāo),碳素結(jié)構(gòu)鋼和優(yōu)質(zhì)碳素結(jié)構(gòu)鋼就是根據(jù)它劃分的:硫,磷含量皆不超過0.04%的鋼,稱為優(yōu)質(zhì)鋼;硫含量不超過0.03%,磷含量不超過0.035%的鋼稱為高級優(yōu)質(zhì)鋼;硫磷含量各不超過0.025%的鋼稱為特級質(zhì)量鋼。
Stainless steel is usually divided into various types such as 201, 202, 301, 304, 309s, 310s, 410, 420, 431, etc. Among them, 201, 202, 301, 304, 309s, and 310s belong to austenitic stainless steel, which does not contain magnetism and can withstand corrosion from various media. 410, 420, and 431 belong to martensitic stainless steel, which has magnetism and high strength, but poor plasticity and weldability. The sulfur and phosphorus content is an important indicator, and carbon structural steel and high-quality carbon structural steel are classified based on it: steel with sulfur and phosphorus content not exceeding 0.04% is called high-quality steel; Steel with sulfur content not exceeding 0.03% and phosphorus content not exceeding 0.035% is called high-grade high-quality steel; Steel with sulfur and phosphorus content not exceeding 0.025% is called premium quality steel.
傳統(tǒng)不銹鋼電梯門套以木工板框架打好基礎(chǔ),不銹鋼折板包,施工速度較慢,人力成本較高,兩人一組,平均每日安裝僅10套左右。
Traditional stainless steel elevator door frames are based on a wooden board frame and wrapped in stainless steel folded plates, which results in slower construction speed and higher labor costs. Two people work in groups, and the average daily installation is only about 10 sets.
