Austenitic stainless steel is softened by solid solution, the steel wire is generally heated to 950 around, heat preservation for a period of time, so that carbide and various alloying elements fully homogeneous dissolved in the Huaux, and then rapid quenching water cooling, carbon and other alloying elements of the precipitate, to obtain pure austenite,

Stainless steel materials are basically corrosion-resistant. At the same time, compared with other metal products, the corrosion resistance is better. Compared with stainless steel square tube, the corrosion resistance is needless to say. However, after long-term use, corrosion and rust can not be avoided, and there are many factors that damage the corrosion resistance, not

Pipe fittings Use of value and range pipe fittings the welding of dissimilar metals can save precious metal and make the product function better. For example, the work of the tool parts (high-speed steel) and tail (medium carbon) of the butt welding, internal combustion engine exhaust valve head (heat-resisting steel) and the tail (structural steels)

The corrosion resistance of stainless steel flanges in all kinds of tubes is the best, because stainless steel flanges can be deactivated with oxidants, forming a layer of tough dense chromium-rich oxide protective film $literal on the surface, thus effectively preventing the further occurrence of the oxidation reaction. Stainless steel flange corrosion is usually manifested

Carbon steel flange storage is very important, the general project will choose carbon steel quality, carbon steel flange surface is very easy to appear floating rust, placing time long appearance is not beautiful, the storage of flanges shall not be placed directly on the ground, put the ground into some moisture-proof cushion, and then put

International Children’s Day is scheduled for June 1 every year. In commemoration of the leditzer massacre on June 10, 1942 and all the children who died in the war all over the world, we oppose the maltreatment and poisoning of children, and safeguard the rights of children. In November 1949, the International Federation of democratic

The process analysis of the socket and the determination of the process plan are based on the geometrical shape and the process characteristic of the socket. Die structure design, especially the design of the die working parts, depends on the shape of the socket. The inner wall of the socket pipe fitting often produces certain corruption, and

Stainless steel flange is a disk-like part, in the pipeline engineering flange is mainly used for the connection of pipelines, in the need to connect the pipeline, each installation of a flange, low pressure pipe can use wire flange, more than 4 kilograms of pressure on the use of welding flange, two pieces of flange

The carbon steel flange according to the seal surface different has many kinds of classification, the flange seal surface form and the use environment has the direct relations, below the small plait to take everybody to understand each kind of different seal surface. 1. The whole plane of the sealing surface type (FF): More for the flat
