FAQ

What kind of material for stainless steel burglarproof window?
Some common stainless steel anti-theft window can be used (including 302 stainless steel tweezers of less than 8, but more than 4, which is the general material of stainless steel, if in the harsh weather conditions may rust), compared to the price of 304 stainless steel will be much cheaper.
Can stainless steel containers hold no salt?
Chlorine ions are widespread, such as salt / sweat traces / sea water / sea breeze / soil, etc.. Stainless steel in the presence of chloride ions, corrosion quickly, and even more than ordinary low carbon steel. Therefore, the use of stainless steel environment requirements, and often need to wipe, remove dust, keep clean and dry.
What is called oil film wiredrawing stainless steel?
Ink drawing is a surface treatment process of stainless steel. After drawing, the surface is brighter. There are filaments, short silk, ink, wire drawing, and other categories.Ink drawing stainless steel refers to the stainless steel sheet which has been treated by this process.
Can the stainless steel be tested with a magnet?
In general, austenitic stainless steel and austenitic stainless steel (non-magnetic magnet can not suck), there are other ferrite stainless steel, with the ferromagnetic (magnets attract). But stainless steel should not be judged by magnetism alone. For stainless steel, whether or not the magnet is sucked on or not, as long as the quality standards are met, it is stainless steel. There are a lot of stainless steel materials in order to achieve better use effect, thus adding other elements, 321 stainless steel material is like this.
Does the alloy steel include stainless steel?
Stainless steel material is usually divided into 1 parts according to the matrix: ferritic stainless steel. Chromium 12% ~ 30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and the resistance to chloride stress corrosion is better than other kinds of stainless steel. 2 austenitic stainless steel. Chromium more than 18%, but also contains about 8% of nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance, corrosion resistant variety of media. 3 austenite ferrite duplex stainless steel. It has the advantage of austenite and ferritic stainless steel and has superplasticity. 4 martensitic stainless steel. High strength, but poor plasticity and weldability. So alloy steel includes stainless steel
Is the 304 stainless steel in general medical or is it?
304 stainless steel is not necessarily medical.304 the main difference between medical grade stainless steel and non medical grade stainless steel is the content of harmful elements contained therein!Medical grade containing harmful elements must be lower than the national standard range, rather than medical grade, generally used mainly for industrial or civilian.
What's the difference between steel and stainless steel?
Stainless steel is a kind of alloy steel, adding more Ci, Ni and other metal alloy elements, more kinds. The common stainless steel is divided into two parts: ferritic stainless steel and austenitic stainless steel.
Why can oxygen Valves be made of stainless steel?
But also in practical terms, stainless steel is easy to obtain, the cost is not high. Oxygen is made in the industry, it is not demanding, do not take precision materials
