Classification and introduction of stainless steel stamping and welding elbows

Stamping processing plants, processing machinery parts stamping parts, stainless steel stamping parts, various hardware parts, can be customized according to drawings; with the development of society, stamping products have been popularized to every household, and stamping products will be used in various fields, including stainless steel stamping Elbow, then what is this stainless steel stamping welded elbow? What's the use? Let's take a look at it with us below; Stamping welding elbow, it uses the same material as the pipe to stamp into a half ring elbow with a stamping die, and then the two half ring elbows are assembled and welded to form. Due to the different welding standards of various types of pipelines, the semi-finished products are usually fixed by spot welding in groups to leave the factory, and the on-site construction is welded according to the pipeline weld level. Therefore, it is also called two-half welded elbow. The material of stamping elbow includes carbon steel, stainless steel, alloy steel and other materials. Carbon steel stamping elbows are cheap and used in large quantities. The alloy steel elbow is used in a special position. The main difference between stainless steel stamping elbows and carbon steel elbows is the difference in material. The chemical composition contained in the elbow will keep the surface of the elbow from rusting for a long time and not easy to be corroded. There are many types of stainless steel stamping elbows; 1. Chrome stainless steel stamping elbows have certain corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and wear resistance. Usually used for power station, chemical, petroleum and other equipment materials. Chrome stainless steel stamping elbows have poor weldability, so attention should be paid to the welding process and the selection of suitable electrodes before heat treatment. 2 Chromium-nickel stainless steel stamping elbows have good corrosion resistance and oxidation resistance, and are widely used in chemical, fertilizer, petroleum, and medical machinery manufacturing. When the chromium-nickel stainless steel stamping elbow is welded, it is repeatedly heated to precipitate carbides, which reduces the corrosion resistance and mechanical performance. Chromium-nickel stainless steel stamping elbow coatings are available in titanium calcium type and low hydrogen type. Titanium-calcium type can be used for AC and DC, but the penetration depth is relatively shallow during AC welding, and it is easy to be red, so the stainless steel stamping elbow uses DC power as much as possible. 3. The chrome 13 stainless steel stamping elbow has greater hardenability after welding and is prone to cracks. If the same type of chromium stainless steel stamping elbow electrode is used for welding, preheating above 300℃ and slow cooling treatment at about 700℃ after welding must be carried out. If the weldment cannot be heat treated after welding, the chrome-nickel stainless steel stamping elbow should be used. Recommended article: How to choose stamping oil in metal stamping processing?
