Stainless Steel Weld Elbow During welding, carbides are precipitated by repeated heating, which reduces the corrosion resistance and mechanical properties. Stainless steel stamping elbows are available in titanium calcium type and low hydrogen type. Titanium calcium type can be used for AC and DC, but the melting depth is shallow during AC welding and it is easy to get red, so stainless steel stamping elbows should use DC power as much as possible. In order to prevent stainless steel stamping elbows from inter-crystal erosion due to heating, the welding current should not be too large, about 20% less than carbon steel electrodes, the arc should not be too long, the interlayer should be cooled quickly, and a narrow weld is preferred.

Stainless steel pipe fittings are a widely used product. The reason why they are so popular is inseparable from their cost issues. The transportation of stainless steel stamping elbows is also part of the user's cost.

1. The quality of stainless steel stamping elbows. The quality of stainless steel stamping elbows can be said to be obvious to all. Due to its production process and mold, the productivity of stainless steel stamping elbows can be said to be high.

2. Market issues of stainless steel stamping elbows. Stainless steel stamping elbows are a product with widespread market applications. Its widespread application also determines the good market prospects of stainless steel stamping elbows.

3. The production cost of stainless steel stamping elbows. This problem has always been the main idea of ​​the market. The status of stainless steel stamping elbows is inseparable from its production cost savings. The production of stainless steel stamping elbows does not require a large amount of raw material waste, and does not require too high personnel training costs. Therefore, stainless steel stamping elbows have advantages in production costs.

4. The standards of stainless steel stamping elbows are targeted. Due to the widespread application of stainless steel stamping elbows, stainless steel stamping elbows have stainless steel stamping elbow implementation standards set for the industry in various industries.

The protection method of stainless steel stamping elbow casting process is as follows:

1. Water enters the crystallizer liquid surface with protective slag (argon on top) protection.

2. Before the tundish is injected with water, the tundish is filled with argon (nitrogen) for about 6 minutes to make the oxygen content in the tundish <2%.

3. Through such protection, the oxygen content in the stainless steel stamping elbow will remain unchanged or decrease.

4. The stainless steel stamping elbow enters the tundish below the molten steel surface through the long water inlet protection, the tundish is sealed with a cover, and the long water inlet and the tundish cover must also be sealed.

5. The water in the tundish of the stainless steel stamping elbow is protected by the tundish alkaline slag, and argon (nitrogen) gas is blown into the tundish during the entire casting process.

6. The water in the tundish enters the crystallizer through the immersion water inlet, and the water inlet and the tundish are sealed.

The plastic processing of stainless steel stamping elbows is often prone to the following quality defects, especially in the bending processing of pipes
