  304 stainless steel plate   is one of the most important materials in home decoration. It is popular by its characteristics:anti-corrosion, hard and bright. So, what is 304 stainless steel plate? What is the difference between 304 stainless steel plate and 201 stainless steel plate? How to distinguish 304 and 201 stainless steel plates 1. 304 stainless steel plate and 201 stainless steel plate have the same luster and matte color if observed from a certain distance. If watch beside it we can find that the color of 304 is saturated and bright, and the hand feels very smooth, while 201 is slightly darker, with low color saturation, and it will feel a bit rough to touch. In the water test, the watermark on the surface of 304 is very easy to remove, while the treatment of 201 is a troublesome. 2. Distinguish by grinding machine: when grinding 304 stainless steel plate, sparks are short and few; while 201 is the opposite, sparks are splashing and many. When you use this method to...

  Points to note when choosing 310S   stainless steel plate : 1. Before selecting stainless steel plates, have to know the purpose and use environment of the stainless steel plates. Generally, 200 series materials are sufficient for indoor use, 304 and other materials are required for outdoor use, and materials above 316 are generally used in acid and alkaline places or coastal areas. 2. Make sure that the material meets the standards when selecting stainless steel plate. Take 304 material as an example: a. From the price analysis, if the price of 304 stainless steel plate is lower than the price of the 301 material in the market, you must check it carefully, it is likely to be a fake; b. Identify whether the pipe surface is stamped Material "304"; c. It can be tested with acidic reagent. Material 304 will not change color after 30 seconds, and 201 will turn black. 3. Observe whether the color of the outer surface and the inner wall of the 310S stainless steel plate is bright...

 310S is a kind of heat-resistant stainless steel with good corrosion resistance and is used in alkaline pipelines for ion-exchange membrane electrolysis. Due to the high technological requirements of this material, it is easy to cause serious pipeline cracks, which will bring serious hidden dangers. Then, welding repair of cracks has become an important repair method. 310S  stainless steel pipe  cracks repair 1. Make preparations before welding and drill φ6mm crack arrest holes 10mm from the two ends of the crack. Then use an angle grinder to grind a groove with a groove angle α=60°, a gap b=3.2mm, and a blunt edge p=1.5mm. The length of the groove is the distance between the crack holes, and the transition surface between the weld and the base metal is ground through the crack stop hole, and the oil, rust and other sundries on both sides of the groove are cleaned. 2. Use welding machine, DC reverse connection, φ3.2mm for bottoming, filling and covering, welding current ...

 Stainless steel material 304: The universal model is 18/8 stainless steel. Products such as: corrosion-resistant containers, tableware, furniture, railings, medical equipment. The standard composition is 18% chromium plus 8% nickel. It is a non-magnetic stainless steel whose metallographic structure cannot be changed by heat treatment. High temperature resistance of 800 ℃, with good processing performance, high toughness characteristics, widely used in industry and furniture decoration industry, food and medical industry. Stainless steel material 430: Also known as 18/0 stainless steel, 430 stainless steel is a general-purpose steel with good corrosion resistance. It has better thermal conductivity than austenite, thermal expansion coefficient smaller than austenite, heat fatigue resistance, added stabilizing element titanium, and welded joints. Good mechanical properties. 430 stainless steel is used for building decoration, fuel burner parts, household appliances, and home applia...
