Stainless steel flanged processing products for rust reasons

Release date:2017-11-23 Author: Click:

Stainless steel flange processing products may have the following reasons:

Standard reference: ASME B16.11, HG/T 21634-1996, MSS sp-83, MSS sp-79, MSS sp-97, MSS sp-95, GB/T 14383-2008, SH/t3410-96, GD2000, GD87, 40t025-2005, etc., can also be manufactured according to the drawings.

Stainless steel flange processing

The socket pipe is made of common materials

The common raw materials of the socket pipe are carbon steel, stainless steel and alloy steel.

The commonly used brand of carbon steel is Q235, 20 #, A105, etc.

There are 304, 304L, 316, 316L, 321, 00Cr17Ni14Mo2, etc.

There are 15 crmo, 1Cr5Mo, 16Mn, 12Cr1MoV, F11, F22, 10CrMo910, etc

Other materials: copper alloy, nickel alloy and other use environment.

Chlorine ions are widespread, such as salt, sweat, sea water, wind and soil

Stainless steel flange appear rusty phenomenon, should be at room temperature impact test, v-shaped gap, there is a certain percentage elongation, strength, good toughness and casting forging flange processing, stamping and welding, widely used in general machinery parts manufacturing.

It is mainly used in construction and bridge engineering to require high quality welding structure.

Stainless steel flange processing may have the following reasons:

Chlorine ions are present in the environment.

Nickel alloy pipe fittings accounted for 86% of our company's output in 2015.

The pipe fitting includes elbow, elbow, flange, tee, tube, cap, head, nipple, etc.

The connection mode has butt welding, socket welding, thread etc.

Chlorine ions are widespread, such as salt, sweat, sea water, wind, soil and so on.

Stainless steel, in the presence of chlorine ions, corrodes very quickly, even more than ordinary low carbon steel.

Therefore, there is a requirement for the use of stainless steel, and it needs to be cleaned frequently to remove dust and keep clean and dry.

316 and 317 stainless steel (after the performance of 317 stainless steel) are of molybdenum stainless steel.

The molybdenum content of 317 stainless steel was a little bit clever than 316 stainless steel. Because of molybdenum in steel, stainless steel, the steel grade overall performance is better than 310 and 304, under the condition of high temperature when the concentration of sulfuric acid is less than 15% and higher than 85%, the 316 stainless steel has a wide range of USES.

316 stainless steel also has good performance of chloride erosion, so it is usually used in Marine environment.
