is a universal stainless steel plate， which is widely used to manufacture equipment and parts with excellent functions (corrosion resistance and formability). In order to adhere to the inherent corrosion resistance of stainless steel， it is necessary for steel to be rich in more than % chromium and more than % nickel. stainless steel plate
3Characteristics and application h austenitic stainless hot strength steel has good corrosion resistance， weldability and thermal strength. h stainless steel is used for large boiler superheater， reheater， steam pipeline and petrochemical heat exchanger pipe fittings.
uHeidelbergWhen the material properties become weaker sharp cracks will expand rapidly and cause brittle failure. Austenitic series stainless steel will not produce brittle failure because of its face centered cubic structure. Austrian technology put stainless steel SUSL (cr-ni-lc) and SUSL (cr-ni-
The binder is coated on the metal surface by chemical adsorption to form a protective silicon film with cross-linked network structure. The discoloration time of samples after different surface treatments was compared by blue dot method. The corrosion rate of samples after different surface treatments was distinguished by brine immersion test
LYigongThe default surface treatment method of ordinary stainless steel plate is (grinding + spraying silver powder paint)，304 stainless steel plate and the shell thickness should be ≥ mm； The default surface treatment method of mirror or wire drawing stainless steel plate is (welding leg grinding + argon arc welding or laser welding，Wigan Xm21 stainless steelHigh development value the thickness is only .mm or other thickness less than mm. The non-standard thickness is basically equivalent to winning the bid. Standard index size (mm) label No. crni standard executive standard gbt- non-standard specific thickness ratio outer diameter steel pipes are produced according to standard
Low temperature embrittlement --- in low temperature environment， the deformation energy is small. In the low-temperature environment， the phenomenon that the elongation and area shrinkage decrease is called low-temperature embrittlement. It is mostly produced on the body centered cubic structure of ferrite series.
The removal of oxide scale of stainless steel pipe includes mechanical method， it is not easy to remove the oxide scale on the surface and make the surface highly clear and flat. Generally， measures shall be taken to remove the oxide scale of stainless steel pipe
jWhen transporting stainless steel plates，Stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe, stainless steel rod - China TISCO Steel Co., Ltd the products shall be fixed in the carriage to prevent the products from colliding with each other or other sharp objects during transportation， resulting in pits on the surface of the plates， which will not only affect the use， but also affect the appearance.
SThe back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.
DQuality documentsThe external force at the service point s， fo is the cross-sectional area of the sample， then the yield point & sigma; S = PS / fo (MPA)，304 stainless steel plate MPa is called MPa， which is equal to n (Newton) / mm (MPA = pa， PA: Pascal = n / m.
dJThe electroless plating Pd film with uniform film and good adhesion was obtained by electroless plating PD process. The surface morphology and composition of electroless plated Pd film on L stainless steel were characterized by electron scanning microscope (SEM)， energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). Through immersion experiment
At low temperature，Wigan Xm21 stainless steelHigh development value the electroless palladium film still has excellent corrosion resistance. With the increase of halogen ion concentration， the corrosion resistance decreases， and the corrosion effect of bromine ion is stronger than that of chloride ion. In the mixed acid medium， the corrosion resistance of electroless plated PD samples decreased with the increase of bromine ion concentration. development
The default surface treatment method of ordinary stainless steel plate is (grinding + spraying silver powder paint)，304 stainless steel plate and the shell thickness should be ≥ mm； The default surface treatment method of mirror or wire drawing stainless steel plate is (welding leg grinding + argon arc welding or laser welding， and then wire drawing or grinding and polishing) [this kind of steel plate]

XShop around and choose affordable thin-walled stainless steel pipe water supply pipe. Comparing the prices of pipes sold by various companies， we should choose carefully and should not buy them at a low price. However the transmission energy consumption of thin-walled stainless steel pipe water supply pipe is low， which saves the transmission cost， so the price will not be too expensive.
Bainite elements nickel and manganese. duplex stainless steel plate can be used to replace L and mechanical properties. Tensile strength: about yield strength: about elongation: about . Due to the microstructure of duplex elements， has excellent mechanical properties and reasonable elongation
iHeidelbergThe Chinese brand of stainless steel plate is crnimoti (CrNiMoTi should also be this brand with drawings). The new brand is crnimoti stainless steel plate. The stainless steel plate is added with Ti in SUS steel to improve the intergranular corrosion resistance.
bVIt is a kind of low carbon high alloy stainless steel. Because the nickel content in its composition is less than %， the steel contains ferrite austenite structure， so it is called duplex stainless steel.
The results show that the welded joint has excellent mechanical properties and corrosion resistance， and can fully meet the requirements of practical engineering. In view of the existence of tritium in the material of retired tritium polluted stainless steel pipeline， and a set of tritium removal technology was developed
