Raw material characteristics and cleaning of stainless steel elbow

The nozzle of the stainless steel elbow is equipped with a lining. Part of the lining is located in the nozzle and fixedly connected to the inner wall of the wide mouth. The other part of the lining is located outside the nozzle. The lining outside the nozzle of the product is provided with Cut the incision. When the stainless steel elbow is connected with the stainless steel pipe, it is easy to connect the device, can eliminate the tension caused by the pipe connection, has a strong anti-deformation ability, and after welding, the joint will not be deformed after long-term use. The stainless steel raw material in the stainless steel elbow is a void solid solution formed by chromium, nickel and other elements in γ-Fe, which should be regarded as the mainstream stainless steel type. The main characteristics of this steel grade are: it has a non-magnetic austenite arrangement at room temperature, its yield ratio is low, its plasticity is good, its welding function is good, and it is easy to be trained and cast-forged and hot-formed. Usually, when the stainless steel elbow is rusty, a special cleaning agent is usually used to clean the rust spots. And it should be cleaned more frequently during daily use. If the stainless steel elbow is dusty or easy to remove stains, it should be washed with warm water or weak detergent, or even soapy water. If the surface of the stainless steel elbow has a sticky film such as a trademark, it can also be washed with a weak detergent, but it needs to be washed with water and wiped dry after washing. The corrosion resistance of stainless steel is affected by the alloying elements contained in the steel body. Among them, chromium is the basic element that provides the corrosion resistance of stainless steel. When the chromium content in the stainless steel reaches about 1.2%, the chromium will deal with the oxygen effect in the external medium to form a thin and dense oxide film on the surface of the stainless steel. The film can prevent the stainless steel from being corroded more deeply.
