The welding parts of 304 stainless steel strips used in mechanical equipment manufacturing are rusted? Here is Hua Steel Co.,the solution!
Through after-sales feedback from customers, some customers who specialize in mechanical equipment use 304 stainless steel strips to weld certain equipment, and the welding points are prone to rust. Why do the welding points of 304 stainless steel strips used in mechanical equipment rust? What should we do? In fact, there are many reasons why the welding points of 304 stainless steel strips rust after welding. HUA STEEL will briefly analyze the reasons and give the correct preventive measures. If you use argon welding when welding machinery and equipment, you need to focus on whether the carbon content of the 304 stainless steel strip can meet the welding requirements and whether auxiliary materials are used. If the carbon content in the 304 stainless steel strip is relatively high, it will easily cause intergranular corrosion during welding. Therefore, customers who need welding should prefer steel types with low carbon content and higher nickel content, such as 304L stainless steel. Hua steel introduces 304L stainless steel, which is a derivative of 304 stainless steel. Except for the carbon content being less than 0.03%, the other components, properties and application range are almost the same. It also has the ability to resist intergranular...

Do you know well that Medical stainless steel It is made of 304L material Or 316L material?
304L is food-grade stainless steel, used in cookware and utensils, corrosion-resistant, high-temperature resistant, healthy and hygienic. 316L is medical-grade stainless steel, the best material among stainless steels, and is used in medical instruments and scalpels. One : Stainless Steel as Biomedical Material is an iron-based corrosion-resistant alloy and one of the earliest biomedical alloys developed. It is characterized by easy processing, low price, corrosion resistance, and the yield strength can be improved through cold working to avoid fatigue fracture. Among them, the most widely used is austenitic ultra-low carbon stainless steel 316L. TWO: The biocompatibility and related issues of 316L medical stainless steel mainly involve tissue reactions (such as edema, infection, tissue necrosis, etc.) caused by corrosion or wear after the stainless steel is implanted in the human body, leading to pain and allergic reactions. wait. Especially the serious lesions caused by the precipitation of nickel ions in stainless steel (the commonly used 316L austenitic ultra-low carbon medical stainless steel contains about 10% nickel). In recent years, low-nickel and nickel-free medical stainless steel are gradually being developed and applied. THREE: 316L medical stainless steel is widely used clinically. (1) Artificial joints and fracture internal fixation devices are used in fracture...

What impact will the surface drawing and oxidation of 304L stainless steel plate have?
Brushed oxidation is a kind of surface processing of stainless steel plates. The surface effect of the plates is relatively good. The unique beauty of stainless steel is displayed in indoor and outdoor spaces in the form of elevators, screens, sculptures, ceilings, etc. However, the effects of wire drawing oxidation on certain stainless steel plates are both positive and negative. For example, 304L stainless steel plate has excellent corrosion resistance and oxidation resistance. However, after drawing and oxidation, the 304L stainless steel plate was degreased and extruded, and some reactions occurred on the surface. At this time, the oxide film of the 304L stainless steel plate may not be as stable as before, and its corrosion resistance will indeed be reduced. On the contrary, wire drawing and oxidation will bring bright and matte surfaces to 304L stainless steel plates. The surfaces of these two are actually more upscale, and many people prefer them. Therefore, we must regularly clean and maintain the brushed and oxidized stainless steel plates to avoid direct contact with corrosive substances. For more information about 304L stainless steel, please consult our staff at Huaxin Steel Stainless Steel.

A simple method to quickly identify 304 and 201 used in stainless steel water tank sheet metal factories
304 stainless steel is often used in the inner layer (that is, in direct contact with water) because of its excellent corrosion resistance. 201 stainless steel cannot be used in the inner layer because of its poor corrosion resistance and can only be used in the outer layer of the insulated water tank. However, 201 stainless steel is cheaper than 304 stainless steel. It is often used by some unscrupulous merchants as 304 stainless steel. Stainless steel water tanks made of 201 stainless steel have a very short service life. They can be corroded by water in about 1-2 years, leaving safety hazards during use. Hidden danger. Let’s teach you how to identify these two materials in a simple way: 1. The surface of 304 stainless steel and 201 stainless steel used in stainless steel water tanks is usually matte. So we can identify it by looking with the naked eye and touching it with our hands. To the naked eye, 304 stainless steel has a very good luster and is very smooth to the touch; 201 stainless steel is dark in color, has no luster, and feels rough and not smooth to the touch. In addition, wet your hands...
