Let PS be the external force at the yield point s and fo be the cross-sectional area of the sample, then the yield point & sigma; S = PS / fo (MPA) MPa is called MPa, equal to n (Newton) / mm (MPA = pa, PA: Pascal = n / M

6Under the corrosion condition of plasma arc cutting, the condensate between the attachments and stainless steel connects them into a micro battery, causing electrochemical reaction and damage to the protective film,Stainless steel strip which is called electrochemical corrosion.

nWhen water-soluble paper is used to block the ventilation,316Ti stainless steel pipeThe downstream purchase is weakened and the shipment is not ideal due to the ventilation from the weld center, the ventilation pipe shall be pulled out quickly at the later sealing link, and the residual argon inside shall be used for protection, so as to quickly finish the bottom and seal the mouth.

Seamless steel pipe belongs to the category with relatively high added value among steel pipe products, and the products involved in this case belong to the medium and high-end products of stainless steel pipe. According to incomplete statistics, in , China exported about tons of stainless steel pipes to the EU, accounting for about % of the total exports of stainless steel pipes that year.

PPisa  — Good heat resistance, weak corrosion resistance,Stainless steel strip % Cr, % Ni.

GgClamping operation the jaw of the caliper must be placed perpendicular to the axis of the pipe and pipe fitting, and the convex ring of the pipe fitting needs to be put into the groove of the jaw for clamping. In order to prevent operation, the operator can only stand on the axis of the pipe, not on the left and right sides of the tong head.

For example, if the actual thickness of stainless steel round pipe is ., the weight of a single -meter-long stainless steel pipe is (-... = kg, and the theoretical weight of a -meter-long round pipe is .. For example, the length can be changed into one meter.


(III) steel exports grew rapidly. The supply and demand of domestic steel market is unbalanced, and the export of enterprises. From January to June,Stainless steel strip China exported . million tons of steel, a year-on-year increase of %; . million tons of steel were imported,316Ti stainless steel pipeThe downstream purchase is weakened and the shipment is not ideal down %, and tons of billets and ingots were imported, up %. Converting billets into crude steel the cumulative net export was . million tons, a year-on-year increase of %, accounting for % of Chinas crude steel output. In terms of export price, the average export price of bars and wires from January to June was US dollars per ton, a year-on-year decrease of %; US $ tons of plate, a year-on-year decrease of %.

eThe continuous casting of stainless steel pipe fittings is generally matched with the refining furnace,tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd which has strict requirements on the chemical composition and temperature of molten steel; In order to prevent secondary oxidation of molten steel, non oxidation protection pouring is required during continuous casting production; Strict requirements for refractory materials such as ladle, sliding nozzle and submerged nozzle.

MThe selection of stainless steel plate shall consider the operating conditions, such as manual operation or automatic operation, the performance and type of hot press, and the quality requirements for materials, such as hardness, gloss, etc. Economic accounting should also be considered. Each time the steel plate is newly polished, it is required to produce a number of decorative plates with slow quality.

ZreformThe package itself needs to be manufactured into

mVProcess performance inspection: flattening test, tensile test, impact test, flaring test hardness test, metallographic test, bending test and nondestructive testing (including eddy current testing, X-ray testing and ultrasonic testing).

Quantity calculation formula steel theoretical weight length (mm) & times; Width (mm) & times; Thickness (mm) & times; Density value = weight (kg) stainless steel plate, stainless steel, duplex stainless steel, stainless steel material, Swedish stainless steel brand. The difference between duplex stainless steel plate and austenitic stainless steel plate is that the yield strength is more than twice that of ordinary austenitic stainless steel, which is conducive to reducing the cost.


Usage: widely used in automobile, tractor and other industries.

Pursuit of excellenceeThe rolling of cold drawn (rolled) seamless steel pipe is more complex than that of hot rolled (extruded seamless steel pipe). The first three steps of their production process are basically the same. The difference starts from the fourth step. After the round tube blank is emptied, it needs to be started and annealed. After annealing, pickling shall be carried out with special acid. After pickling, apply oil. Then it is followed by multi pass cold drawing (cold rolling) and special heat treatment. After heat treatment, it will be straightened.

SFerritic and martensitic stainless steels are represented by series numbers. Ferritic stainless steel is marked with and , martensitic stainless steel is marked with and C, dual phase (austenite ferrite).

cold rolled oriented silicon steel strip (sheet) represents: times of DQ + iron loss value (at the frequency of Hz, the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of T) + times of thickness value. Sometimes G is added after the iron loss value to indicate high magnetic induction. For example dq represents cold-rolled oriented silicon steel strip (sheet) with iron loss value of and thickness of .mm. Now the new model is q.

yStainless steel has the ability of atmospheric oxidation, that is, it does not rust. At the same time, it also has the ability of corrosion resistance in the medium containing acid, alkali and salt, that is, corrosion resistance. However its corrosion resistance changes with its own chemical composition, service conditions and environmental medium type. For example, has absolutely excellent corrosion resistance in dry and clean atmosphere, but it is moved to In coastal areas, in the sea fog with a lot of salt, it will soon rust, while stainless steel performs well. Therefore, not any kind of stainless steel can resist corrosion and rust at any time

fUCold drawn (rolled) seamless steel pipe: round billet → Heating → Perforation & rarr; Lead & rarr; Annealing & rarr; Pickling → Oiling (copper plating) → Multi pass cold drawing (cold rolling) → Blank tube & rarr; Heat treatment & rarr; Straightening & rarr; Hydrostatic test (flaw detection) → Mark & rarr; Warehousing.

, because the family kitchen and are in a humid environment for a long time, the ordinary steel pipe will rust after being used for a period of time, the service life is not long, and it will affect the safety of family drinking water! Therefore, the use of stainless steel pipe here can ensure long-term non rusting, and the corrosion resistance and tensile resistance of stainless steel pipe itself. Professional sales of stainless steel plate, stainless steel belt, stainless steel pipe, safety, environmental protection, economy! The products are exported to foreign countries and are deeply trusted, which makes the stainless steel pipe more and more popular in the field of home decoration!
