Stainless steel industrial welded pipe food hygiene pipe
About the stainless steel pipes, from the type ,we can idenfity is welded and seamless. As today we talk is for the food hygiene pipes.The welds of food hygiene pipes produced by our company can be seamlessly processed, and there is no shadow on the welds. The whole process is high-precision mechanical polishing with a thousand-impeller wheel, and the internal polishing Ra value can reach below 0.2μm, which is smooth and traceless, meeting various inner wall requirements; full nitrogen protection welding, pure hydrogen annealing protection, and high strength of welded pipes and welds. After testing, the tensile strength is above 690Mpa; the expansion rate is above 30%; the welds do not burst in the expansion, shrinkage, curling, bending, and flattening tests, and the processing performance is good. The surface is free of corrosion in the 1000-hour salt spray test. The hot material grade :304 ,304L, 316,316L The size according to your need. Usually the standard we according to ASTM A270 ,ASTAM A269 ,JIS G3447 . Package: each plastic bags of each pipes ,or 10 pcs with one plastic bags . Anyway,if you need BA pipes , talk with Zyta for getting more stainless steel welded pipes .Just most of customer...

Do you know what the maximum width of 304/304L austenitic stainless steel thick plates that HUA STEEL can provide is?
We all know that the thickness of stainless steel plate ranges from about 3.0 to 200 mm. So how wide can the widest stainless steel plate be? The current national standard GB/T 4237-2015 “Hot-rolled stainless steel plates and strips” stipulates that the width range of stainless steel thick plates is 600~4800mm. So that HUA steel company can provode the width is 4800mm ,which belongs to customized. What can wide and thick 304/304L stainless steel plates be used for? Zyta will briefly introduce the characteristics and uses of the two stainless steel types 304/304L. 304 stainless steel is the most common and most commonly used steel type, with a carbon content of 0.08%. It has good corrosion resistance, heat resistance, low temperature stress and mechanical properties. It can be used for hot processing such as stamping and bending, and will not show heat treatment hardening. 304L stainless steel is a derivative steel type of 304 stainless steel, with a carbon content of 0.03%. Under normal circumstances, its performance is similar to that of 304 stainless steel. However, due to its extremely low carbon content, it can maintain excellent resistance to intergranular corrosion after welding or stress relief, which 304 stainless steel...

Are the higher the grade of stainless steel such as 201, 304, 316L, the better?
Stainless steel with a grade of 201, 304, 316L, etc. is not better as the grade increases. It just represents the corrosion resistance of stainless steel. Moreover, there are many types of stainless steel. In theory, there is no difference between “good” and “bad”, because different stainless steels have different uses. Here, Zyta needs to share some knowledge with you. The main alloying elements of stainless steel are carbon, chromium, and nickel. Chromium is the most basic element that determines the corrosion resistance of stainless steel. When the chromium content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally contains at least 10.5% chromium. In addition, stainless steel also contains alloying elements such as titanium, manganese, nitrogen, niobium, molybdenum, silicon, sulfur, and copper, which constitute stainless steel with different grades (201, 304, 316, 430…). According to the organizational structure, stainless steel can be divided into austenitic stainless steel, martensitic stainless steel, ferritic stainless steel, duplex stainless steel and precipitation hardening stainless steel. According to the alloy composition, stainless steel can be divided into 200 series chromium-nickel-manganese austenitic stainless steel, 300 series chromium-nickel austenitic stainless steel, 400 series ferrite and martensitic stainless steel, 500 series heat-resistant chromium...

Stainless steel tips: Why do stainless steel coils and sheets use paper involved?
Why do stainless steel rolls use pad paper? The purpose is very simple to protect the stainless steel plate in rolling, pickling, flat, mirror, wire drawing, titanium plating and other processing processes, as well as storage and transportation these usually require the use of pad paper in the stainless steel plate between the finished products, protect the stainless steel plate bright and smooth surface, to prevent friction between the stainless steel plate caused by scratches, bumps, creases, impressions and so on. Because many customers have high requirements for stainless steel surfaces, these defects are not allowed to appear on the stainless steel surface, at this time the protective effect of the paper on the stainless steel plate is obviously important. If you have other stainless steel information for coils, plates, bars talk with Zyta. No matter the material grade is 201,304,304L,309S,310,316,316L,409,410,420,430 etc, duplex 2205, duplex 2507 .
