Aathaworld is your preferred stainless steel pipe, tank, customized steel products supplier in Malaysia, cover KL Selangor, Klang Valley, Johor and other states of Malaysia. From French language, stainless steel is also called as inoxydable (inox steel). Steel alloy has a chromium content by mass at about 11% minimum as well as its carbon mass content is approximately 1.2% at the maximum. The world of metallurgy, many research and technical knowledge have been accumulated in which we could master through proper study. It is actually known as the domain of materials engineering and science comprise of metallic element’s behaviour such as its chemical and physical, mixture, compound within their intermetallic and alloy. Few of the metal engineering are very common, such as magnesium, iron, copper, zinc, titanium, nickel, aluminium, chromium and applied as alloys. A lot of efforts have been allocated to make the system of iron-carbon alloy more understandable, including cast irons and steels. According to stainless steel pipe supplier in Malaysia, simple alloy element such as carbon, also known as carbon steel is applied in many aspects as corrosion and weight cause no issue and its high strength at low cost makes it economical to have mass production. In addition, iron-carbon system also comprises of ductile iron (cast iron).
Magnesium alloys, magnesium alloys will be used when lightweight strong materials are needed for that specific application while galvanized or stainless steel when anti-corrosion is essential. By having a zinc coating on top of the steel surface for corrosion prevention, it is known as galvanized steel. Stainless steel is on the other hand, mixing 10% or more of chromium during moten state. Hot-dip galvanizing (HDG) is a very common method for galvanized steel to be used. Stainless steel pipe supplier Malaysia says that the parts will be submerged in the molten zinc bath but galvanized using hot dip is very expensive yet painting cost will increase more than galvanizing as a comparison. There is another method in this finishing, known as the powder coating. It can resist peeling, cracking, rust, abrasion, chipping, and other damages when steel exposed to chemical. It is also UV-resistant, can retain gloss surface, colour and basically is a very durable finishing. Any kind of metal objects can even use this method as finishing, making its demand increased every year. Market works pretty simple and well when come to demand in correlation with supply and price; when demand more, supplier will enter into the market and price will eventually goes down. Therefore, stainless steel pipe supplier in Malaysia claims that powder coating is a relatively cost effective metal finishing way when customers want to save more cost while enjoying its features. Electroplated steel, galvanized, aluminium, stainless steel or mild steel as well as other steel alloys can hold the electrostatic charge required during the powder spraying process, they can tolerate the high heat level during the curing process of this powder coating method.
Stainless steel is famous with its superior feature, corrosion resistance and it will be enhanced through chromium content. There is another element name molybdenum can be added into, in order to further increase its corrosion resistance strength through acid reduction against chloride solutions’ pitting attack. The variation in both molybdenum and chromium contents will define its stainless steel grade, according to stainless steel pipe supplier Malaysia. Stainless steel minimum requirement of chromium content is approximately 10.5 percent and of course the most widely used stainless steel grades are 316 and 304 (SS316 or SS304). The alloy element, molybdenum is the additional part that distinguish its difference, further improves the resistance level against corrosion. Two kinds of elements that will make the environment more prone to corrosion are those conditions that makes steel exposed to chloride and saline. The chromium is typically ranging in between ten to twenty percent, this alloying element makes stainless steel able to achieve two hundred times more corrosion-resistant compared to other steels, such as mild steel. Let us take example of food grade industry, SS316 is a stainless steel alloy that is austenitic, containing high nickel and chromium. Furthermore, SS430 is also another commonly used in food industry in accordance to stainless steel pipe supplier in Malaysia.
Stainless Steel Pipe and Tube
Steel pipes are used widely because of its robust advantage, it can be applied for gas, water transportation as well as other fluids, steams and protection of wires. In addition to pipe, it can also comes in tube where different sizes and shapes are available. For the piping industry and specifically for steel pipe, grade 304 is the most common to be applied because of its chemical resistance, can be installed for industrial purpose for extensive volume of water flows. Of course, up to certain degrees like 420 plus celcius, SS304 will not be a suitable one due to its carbide precipitation susceptibility. In this case SS304L will be substituted, as 304L has a lower carbon, indicated by its “L” while both 304 and 304l have a maximum 0.08% carbon content. At the same time as per stainless steel tube supplier Malaysia suggests for usage, would be the pressure pipe, i.e. seamless pipe, large diameter welded pipe, electric fusion welded pipe and welded pipe. High pressure, corrosive and temperature environments are both conditions where these appropriate produced pipes are suitable to be used. In the aerospace industry
