Under what circumstances must 316 materials be used?

As we all know, 304 stainless steel is one of the most widely used stainless steel materials on the market. Some people may ask: Under what circumstances must we choose to use 316 stainless steel instead of 304 stainless steel? Stainless steel pipe manufacturers summarize the following four situations: Under what circumstances must 316 materials […]

Austenitic stainless steel should also pay attention to: cold work hardening, high temperature aging embrittlement

Everyone is familiar with the intergranular corrosion and stress corrosion cracking problems of austenitic stainless steel. The intergranular corrosion tendency test of stainless steel is common content in design documents, and the relevant content in standards such as HG/T 20581 is also relatively clear. The hydrostatic test or the chloride ion content in the operating […]

Do you know the importance of preheating before welding and post-weld heat treatment?

The importance of preheating before welding and post-weld heat treatment Preheat before welding Preheating before welding and heat treatment after welding are very important to ensure welding quality. The welding of important components, the welding of alloy steel and the welding of thick parts all require preheating before welding. The main functions of preheating before […]

For heat treatment of austenitic stainless steel, these key issues should be clarified!

Austenitic stainless steel, as its name implies, has an austenite structure. The heat treatment of austenitic stainless steel is very important because the important task of austenitic stainless steel is corrosion resistance. If the heat treatment is improper, its corrosion resistance will be greatly reduced. This article mainly tells you about it. Heat treatment of […]

Things to note when bending stainless steel plates

Things to note when bending stainless steel plates 1. The thicker the stainless steel plate, the greater the required bending strength. As the plate thickness increases, the bending strength must be adjusted accordingly when adjusting the bending machine. 2. In unit size, the greater the tensile strength of the stainless steel plate, the smaller the […]
